The Trinity Buoy Wharf Drawing Prize winners announced.

M. Lohrum: You are It.

It is always fascinating to see the final selection and winners that are picked out in the annual Trinity Buoy Wharf Drawing Prize. It works as a sort of litmus test as to the current state of drawing led practices and especially this year in a time of lockdown. My own added personal interest was that I had submitted a collaborative piece this year, that made it through the first round but no further; so I was of course fascinated to see what did win.

M. Lohrum’s 'You are It' was the overall prize winner and for the first time a performative drawing has won. It reminded me of Sol Lewitt drawings that were also made from written rules, his impermanent wall drawings consisting of sets of the artist's instructions, so that their actual execution could be carried out by someone else. There is though a difference. In M. Lohrum’s case the audience is engaged directly in the drawing's execution, in Lewitt's case it was usually student volunteers or gallery staff who made the drawings and when you did get to see the work it was usually already completed. 

Sol Lewitt: Wall Drawing instructions

M. Lohrum is less 'authorial' in the control of the work, and there is more an emphasis on collaboration and participation, which I think reflects a shift in attitudes that has taken place since Lewitt began producing his work in the late 60s. Lewitt came from a time when the status of the artist was more or less unquestioned, artists were the avant-garde, the romantic initiators of new ideas and as such their name was very important, as it was used to in effect 'brand' their practice. We are living in different times, the status of the artist has been questioned and in particular the role of the artist as maker of 'honorific objects' that are to be collected by rich individuals and displayed as cultural capital in museums and art galleries is perhaps coming to an end. Of course the art market still exists, but it seems to have less and less relevance to many an artist's everyday life. My own recent experience is that as an artist I have become more embroiled in interdisciplinary activities, especially those related to health and wellbeing. The artist still has a role in society, but perhaps it is one shifting away from a capitalist idea of the producer of a particularly rare cultural commodity and is moving gradually towards an idea of the artist as catalyst or instigator of alternative ways of approaching life. Artists have always been associated with raising awareness, seeing something more in the everyday than the everyday, and it would seem that in times of a lockdown we need this quality more than ever. As the selector Frances Morris stated “The invitation to members of the public to participate as anonymous makers and the work’s dependency on collaboration between strangers, felt timely and necessary, speaking to the power of art to bring people together”. It is not of course just that a work like this brings people together, it also reminds us of the central position of our bodies in the making of meaning. Every drawing that has ever been made is in one way or another a seismographic record of the person that made it. Each one of us has a different ratio of arm length to height and to hand size; we are all unique in relation to the type of heart beat we build our life's rhythm to and in the way that our nervous systems are wired up. Each person participating in this drawing, as they are instructed to draw from their shoulder will immediately be aware of the weight of their own arm and of how well it operates as it moves around in its shoulder socket. Body awareness is of course vital if we are to maintain a sense of our own well being, an awareness not just of our selves but of other people's bodies is essential to the building of empathy with others and the development of our collective sense of community care. 


Nancy Haslam-Chance: 'Caring Drawings'

It was very interesting therefore to see that the second prize had been awarded to Nancy Haslam-Chance for her 'Caring Drawings'. These pencil drawings are a long way from the fine artist's 'signature' drawings that forefront a special touch or individuality of approach and instead these drawings document her role as a carer and support worker. These drawings are more like those we might find in a visual diary, and they focus on the physical and emotional relationships she has formed with her clients.  The daily details and practicalities of her job are drawn from memory between shifts, an important reminder that artists need to ground their practice in reality if it is to communicate to others. This type of reality has of course in a time of COVID become much more visible, but carers have always been there working to support other human beings who have fallen on hard times, we just needed a reminder and Haslam-Chance has given it to us. 

Nancy Haslam-Chance: 'Caring Drawing'

Both these artists have produced work that has emerged out of a crisis, one that will hopefully have been overcome by the time the next Trinity Buoy Wharf Drawing competition is run. I would hope though that what their work intimates is that there is a move towards a rethinking of the role of the artist in society. A role that is less to do with individualism and one much more to do with self awareness, community cohesion and spiritual well being.

Texture: Between drawing and sculpture

Tom Friedman: Soap and hair 1990

This very controlled line drawing by Tom Friedman is made of his own pubic hair and a block of soap. What is interesting about it is how it makes us think again about what is an everyday experience of hairs in the bathroom. We are disgusted when other people's hair gets stuck in the soap, and as a textural experience we usually associate it with the abject. However the process of geometrically controlling the shape of the hair as it is formed over the soap, allows Friedman to lay this hair down as if it follows the groves of a record, the precise circular geometry it now follows, moves us away from the abject and we begin to enter the territory of the sublime. The soap now becoming linked metaphorically to the geometry of the cosmos, the rings of Saturn or oscillating sound waves. 
The soap and hair piece was an object that came from a series, all of which had their origin in 'bathroom materials'. 

"Initially I was drawn towards materials that had to do with personal hygiene. Cleaning materials. There are all sorts of incidents that sort of redirect me or clue me in to things: things that just happen and become significant to me rather than having a very logical reason for them. I came to using cleaning materials when I was in graduate school."  Tom Friedman 

Friedman refers to the fact that the process behind the work began while he was still at college. He wasn't clear about what was happening and part of the initial idea was derived from a conversation with another student. This 'messy' start is typical of many ideas, they gradually resolve themselves as they are worked through. I. e. there were quite a few 'failures' made before he hit upon the idea of the hair and soap bar. This is an artwork that relies on changing expectations as to the surface texture that we would expect to find on a bar of soap. However some textural ideas are less context specific and rely for their effect on the building up of surfaces from small units. 

Pia Männikkö’

Pia Männikkö 2018 'Some people knit'

Pia Männikkö

Pia Männikkö’s forms are made from small circles of masking tape. I've mentioned tape as a drawing material before, but usually as a linear element, in this case the circles of tape create a rich texture reminiscent of undersea life. As in nearly all forms of drawing a texture is built up by repetition. These types of forms are essentially creations based on repetition, for instance chain mail or the many forms of wire fencing. Its one of those areas that sits between drawing and sculpture, as it is about developing surfaces and as the surfaces are developed they in effect become textures. Constructed from basic elements in a very similar way to drawings, they are also types of textiles, lines of material 'woven' or 'knitted' to produce continuous surfaces. Textiles and texture and text can all be traced back to the same latin root, texo, to weave.  Words are “woven” together to weave a tale“ and spin a yarn, and as the text builds up across this digital surface, another textural pattern is developed. 



The artist El Anatsui uses thousands of metal bottle tops, as well as that thin metal you sometimes get that covers the tops of champagne bottles. He joins each piece by using small loops of wire to construct large sheets of complex texture, that once made can be draped, bundled up or made into other forms, by being 'stitched' together using the same copper wire that joins all the individual elements. 




El Anatsui

I think of this as drawing rather than sculpture because it is to do with surface and not mass. These pieces operate like huge sheets of paper or textiles, their own weight causing the material to fold and bend. This is texture as materials play, a product of the careful linking together of basic units. Just think about what can be done with a box of paper clips and some post-it notes, anything that can be sourced in great numbers can be turned with a little invention into a textured surface. 


Jan Fabre

Jan Fabre, the Belgian multidisciplinary artist, playwright, stage director, choreographer and designer, often uses repeated units to develop intense surfaces for his 3D objects. In the case of the torsos above he has sourced thousands of dead beetles and in the figure with the hat on, he has developed a surface composed of drawing pins. His surfaces sometimes feel as if they have been encrusted with undersea forms, something that other artists have taken literally. Jason deCaires Taylor's 'The Silent Evolution' project', encourages coral, sea urchins and other marine life to take over his sculptures, so that they develop a totally new and alive surface texture.

Jason deCaires Taylor: 'The Silent Evolution'

Simon Starling has used the same idea to comment on Henry Moore's ubiquitous presence in the major cities of the world, leaving a full sized replica of one of Moore's warrior figures for two years underwater. Starling takes two unrelated stories of what he terms 'alien introduction' and finds a connection between them. He found lots of Moore's sculptures in Toronto as well as an infestation of Russian zebra mussels in the Great Lakes. Starling suggests that both Moore and the zebra mussels came to 'infest' Toronto with European maladies. 

Simon Starling: Infestation

Aganetha Dyck develops the surface of her objects by leaving them in specially designed apiaries. Her objects are slowly transformed by the slowly growing bees’ wax honeycombs, and as they are transformed, like Jason deCaires Taylor's work, we are reminded that there are other creatures in this world besides humans and that in the case of the bees, our ever expanding use of chemical products has decimated many of the world's bee populations. 


Aganetha Dyck 

It's interesting to compare Pia Männikkö's masking tape surfaces with Aganetha Dyck's honeycombs, they are structurally very similar. Dyck is though also referring to the fact that bees are having a hard time at the moment. Over use of chemical sprays has decimated many of our bee populations and paradoxically they are now safer in cities than in the countryside. 
The fact that bees build structures that are not that different from human artists, hopefully helps us to develop a little more empathy with them and their plight. Perhaps we might contemplate caddis fly larvae and their building habits or puffer fish and their circular constructions with more thoughtful and empathetic insight in future, however I'm not sure we are really capable of getting over our obsession with capitalism. For instance, French artist Hubert Duprat uses the Caddis fly larvae instinct to collect natural, substrate materials like sand, gravel, leaves and twigs to build protective shells around their bodies. He puts them in special isolation tanks, and gets them to use their excreted silk to hold together the gold, pearls and precious stones like sapphires and rubies, that he puts into these tanks. He then sells the results of this 'collaborative' venture as very expensive exotic fashionable jewellery. I suppose this is no different to the many other human/animal/vegetable/mineral collaborations that humans have forged over the course of many lifetimes. A Roman general's purple robes, were dyed with an extract of the murex shellfish,10,000 of which were needed to produce just one gram of dye. One pound of murex extracted purple dye cost 150,000 denarii or around 3 pounds in weight of gold. The transfer of animal or vegetable lives into capital, is a strange thing indeed. During the time of the Dutch 'tulip mania' the bulb of a tulip, known as "the Viceroy" was offered for sale for between 3,000 and 4,200 guilders, about ten times the yearly wage of a skilled craftsman. If we then throw into this mix the price of an artwork by one of todays blue chip artists, lets say a Jasper Johns 'Flag' painting which recently sold for $36,000,000 dollars and we can see a recurrent theme that has been part of human life for a long time. There is no such thing as intrinsic value, the worth of something is dependent on what a residing economic power decides is valuable. When it comes to the most expensive things, there will usually be some sort of scarcity factor and some aspect of cultural kudos, whether this is the 'rich beauty' of a hard to achieve purple, the attraction of owning a rare and exotic tulip or the salesroom achievement of being able to outbid everyone else in the gaining ownership of the works of one 'special' individual, who's productions are deemed to be in some way unique. All of which seems far away from simply valuing the experience of texture, but there is a continuous thread that links aesthetic value to monetary value. If you have time to spend contemplating how interesting a texture can be made by rolling small tubes of masking tape and sticking them together, you are probably not having to work all hours of the day labouring in the fields; having time to appreciate things is a luxury, especially an appreciation of the textures of rich surfaces. It is in that small gap between having to work all day to survive and having time to value things that possessive attitudes can develop, instead of the things you appreciate being gifts that can be a bounty for all or having a practical use for everyone, they can become something that Marx called fetishes. The value of objects is simple and straightforward as long as it is linked to their practical or social use-value. However when it becomes a commodity, something changes, it is as if value is inhered in the object itself and not the process that it is part of. This severing of the object from its place in a process, is what lies at the core of our lack of empathy with the rest of the world. The entangled processes that underpin relationships between people, plants, animals and materials are replaced by capital, something that sits in a thing or object of value, rather than in a process; something seen as a possible possession by an individual, rather than an aspect of social life, thus separating the object out of the system and giving it honorific status far beyond its actual use value to the world. It is now only of value to the individual investors that have raised money in order to access the cultural capital that these objects possess. 
This text has now been woven, and a texture has been created, a surface rather like a textile, that can now be used, possibly to wrap around you as an idea, or to help you think about a different way to use textual surfaces in your work or to use simply as a distraction, a text to read whilst looking for something else.

Drawing textures (Part two)

When thinking about texture and drawing the majority of people will I'm sure think of those drawing exercises many of us encountered when we first began going to art classes. You were often set off to look at how to make 'actual' textures. Usually by making rubbings or frottage, then to create textural surfaces using the various materials at hand, scratching into paint surfaces, dabbing watercolour or ink with natural sponges, making your own applicators from old paint brushes or spiky teasels, laying paper over a still wet paint surface and rubbing your hand over the back of it, then peeling it off to reveal your surprise texture, crumpling your paper etc etc. We were asked both to make freeform surfaces of these textures and to tape out very clearly measured out rectangles, that we had to place our textures into. These were arranged in rows and targets were set such as a minimum of 50 different textures, and then once our tutors had decided enough was enough, they stopped all the frantic textural invention, and then asked us to think about what these surfaces might communicate. Did they look like other things? Did they have any emotional associations? Besides making a few notes in a sketchbook, I don't  remember doing anything else with all those sheets of textural information. We would then very quickly move on and the next exercise would usually be about observed texture or how to create the illusion of a textured surface by making changes in tone. The one I particularly remember was to create the illusion of texture wrapping itself around a curved surface. We made marks that got smaller as the surface moved away from us and then had to think about the way the marks got closer and closer to each other as they created the illusion of a moving surface. Then we had to adjust the marks tonally to create an added illusion of atmospheric perspective, sharp edged darker marks in the foreground and softer lighter marks in the background. Finally as texture followed the shape of the surface beneath, we had to look at how tonality changed in relation to light direction and how we could account for this at the same time as atmospheric perspective.  It's an exercise still worth doing if you want to think about how to build up your ability to draw objects in space, in particular I remember the penny dropping that what I was actually drawing was light and how it operated in the world. Once you realised this, suddenly Impressionism began to make sense. 

Typical sheet of drawing textures 

In these exercises, you were looking at the relationship between invented and simulated textures, and in both cases it was 'illusion' that was the key issue. Did your invented texture look like something else, or did your simulated texture actually look like the surface you had been looking at or touching. (We were encouraged to feel the surfaces we were drawing to get a better understanding or 'feel' for them). However my personal relationship with this textural exploration was always that of the daydreamer, these surfaces became my hallucinogenic tab, and I would find myself visiting landscapes of mountains or forests, as I rediscovered what many artists had before me, that imagined images can easily be provoked into being by gazing at the splots and blotches of surface textures. This ability to see images in surface texture was even given a variety of names by the Surrealists, such as decalcomania, grattage and frottage.*

Typical texture exercise showing how textures change as they respond to light and form

Thinking back at that time, we were never asked to then really explore the implications of texture, the experience of looking was seen as something that was more about seeking out where edges were, or thinking about tone, light and atmospheric perspective. It was as if conceptual thinking was much easier when you had stripped your looking down to basic elements; for instance 'giron and fesspoint' drawing never included any reference to surface texture and the still-life setups tended to consist of various objects painted white, so that you could assess tonal values. 

Textural conjecture was often left alone, or was something you came to last, and in the classical drawing texts at the time, such as Kandinsky's 'Point and line to plane' texture came after all the other elements in a progression through point, line, plane, form, tone and colour. However, I'm not sure this was right. After having to think about the role of texture mapping in CGI, and how it 'authenticates' certain types of experiences and makes you much more aware of touch, I'm wondering how to bring textural thinking back. Point to line to plane, suggests the primacy of not just vision, but a certain atomistic attitude, that is about breaking things down into their primary parts, rather like looking for the atom inside an everyday material. But what if what I really want to do is immerse myself in the heady sensations of textural surfaces? 

I did like this quote from  the virtual drawing instructor, "Think of texture as icing on a cake and think of the cake as form. Icing makes a cake look great but even without the icing it is still a cake. Without the cake, however, the icing is just a pile of goop". 

Hurst sums up what most of my drawing teachers had to say. I can see the problem, my references to Plato and CGI texture mapping in the last post, reinforce the idea of texture being about some sort of deceit or attempt to fool the eye and when I come to think about it texture was at the root of my early art education experience, the greats I was told were the Italians, such as Michelangelo and it was only later that the Northern Europeans such as Van Eyck were discussed, and in many ways as an afterthought, or as the “Flemish Primitives”. I was taught that the Italians like Michelangelo had stripped form down to essentials, and if you compare the simple solidity of Michelangelo's figures with Van Eyck's almost hyper-real surfaces, you can see the argument as was set out at the time; an argument whereby Michelangelo had achieved greatness by stripping away the inessential and giving us a monumental, weighty image that had real gravitas, whilst Van Eyck was demonstrating his undoubted ability to render surfaces with conviction, but it was argued he failed to see the deeper 'classical' ideal of forms that were Platonic in nature and which didn't depend on 'cheap' surface gleam to get over an idea. 

Van Eyck

Michelangelo

In each case texture seemed to be associated with illusion and illusion with deceit. I gradually though as I got older began to seek out Northern European paintings and as I went around various national collections or visited the churches of major European cities would always look for Van Eyck in particular. I was stunned by his ability to render surface detail, the illusion sucked me in and rather than keep my distance or remain cool, I allowed myself the luxury of immercing myself in the enticement in the illusion. It was if I had discovered a guilty pleasure. So what's going on here?

Intellectually I have been educated to think of the painting or drawing of things, in such as way that their physical presence is heightened, as being to do with the rise of Capitalism. As Julia Fiore put it when referring to the textual realism of Dutch still-life painting, "it’s no coincidence that the still life arose as an independent genre of Europe parallel to the birth of early market capitalism and the world’s first consumer society". From Artsy.net Fiore goes on the remind us that if we focus on things that we want to own, we also need to ask questions such as, "Who consumes what, and at whose expense?" Any theoretical focus of course cuts one understanding off from other readings, a Marxist focus on commodity fetishism can underplay the importance of colonial history, a focus on formalism can ignore the fact that all art objects are always part of a process of some sort and that they never can in reality be read in isolation. 

However when I look at Van Eyck, it is as if the surfaces in his paintings are transcendent, the humans that inhabit his paintings seem almost insubstantial in relation to the various surrounding textured objects and their surfaces, a reminder that in a material world no one thing is more important than another, all are in fact interconnected and their existence is part of a commingled set of processes and events. I wasn't around in the early 15th century and understand that all works of art are open to the interpretative needs of their own times. The early 21st century it would seem to me needs a dose of spirituality to help us get over a sense of ennui, so perhaps a rereading of textural surface is due, one that celebrates the equality of everything under the light of the sun, one that makes us value things as well as people, one that makes us realise that everything has value, not just the life of human beings; one that reminds us that everything is interconnected. In order to do this perhaps we need to return to that hallucinogenic aspects of texture. Its dual nature, as both a way of giving realism to objects and of being a doorway into the imagination, suggests an idea of texture behaving as a hinge, something that can dissolve or shape-shift and move between the worlds of matter and energy, between reality and the imagination. There is an everyday experience of looking at a surface from a distance and thinking it is a quality belonging to an object such as a carpet or a table, and then as you get up really close to it, you lose focus on the object and the texture becomes another something, a world totally disassociated from the object, a landscape of dreams. This mutability reminds us that nothing is fixed, and that the universe is a dance of ever changing relationships. 

Surrealist definitions

Frottage is the activity of taking a rubbing from a textured surface, by laying a thin sheet of paper over it and rubbing chalks, wax crayons or graphite over the back of the paper, so that a textural image is created.  Max Ernst introduced the word into the surrealist lexicon, he had been inspired by the exposed grain of a well worn wooden floor that suggested images to him. It's not enough just to make the rubbings, in order for it to be true 'frottage' the surfaces that have been brought out of their located position in the world, also need to be represented as the visions that they have inspired. 

Max Ernst: Frottage

Grattage or the use of scraping techniques to reveal textures, is a way of layering stiff paint over a canvas that can then be laid over a heavily textured object. Then you scrape the paint off, which will collect more in the indentations and be removed from high points. Ernst liked to use organic surfaces like fish skeletons or plant forms to stimulate his imagination. 

Max Ernst: Grattage

Decalcomania was the technique of placing a clean sheet of paper over another one that had just been painted over and then peeling that surface off to reveal the resultant texture. Sometimes thick paint would be used and sometimes watered down pigments, as long as the paint was capable of being transferred from one surface to another the technique would work. Sometimes the paper surfaces would be moved so that the paint was pulled in one direction or another, to further increase the possibility of unexpected imagery. 


Oscar Dominguez: Decalcomania

The Surrealists were re-discovering a very old tradition that goes back as far as you can go back in the history of art. For instance Cozens's 'blot' technique was an 18th century version. His 'A New Method of Assisting the Invention in Drawing Original Compositions of Landscape' was focused on the blot, which as he stated was a 'production of chance' , which generated 'forms without lines from which ideas are presented to the mind'. You can find images of animals painted in caves 40,000 years ago that were made using the same process. 

Alexander Cozens: A Blot: Landscape Composition

"You should look at certain walls stained with damp, or at stones of uneven color. If you have to invent some backgrounds you will be able to see in these the likeness of divine landscapes, adorned with mountains, ruins, rocks, woods, great plains, hills and valleys in great variety; and expressions of faces and clothes and an infinity of things which you will be able to reduce to their complete and proper forms. In such walls the same thing happens as in the sound of bells, in whose stroke you may find every named word which you can imagine." Leonardo da Vinci

Drawing textures


Physiography from Principles of Cartography by Erwin Raisz 1962


Texture is used to define surface difference. If you look at the textural patterns for various types of geographic landscapes as they might be rendered on a map above, you quickly get an idea of how we use texture to identify differences in physical nature or surface appearance. These differences are what we have become used to as indicators of the thingness or physical quality of objects. We are aware of metals being very different to textiles and that these are different to skin or bone. When we look at the recreation of 3D form in CGI there are three basic levels of 'realism'. The first is the wire frame construction, which I have looked at recently and which has emerged from 'cross contour' drawing practices, linked to technical drawing and perspective conventions. The second level of realism is usually the use of tone to describe form or shading. Phong shading tends to be the default in contemporary 3D computer graphics and it is a type of shading I objected to when I first became interested in 3D computer rendering, because I felt it tended to make everything look like plastic. The next level in terms of visual realism is texture mapping, usually applied alongside Phong or other types of shading software, a process that allows you to take a simple polygon and give it the appearance of something far more complex. The texture map's parametric textural information is tied to the individual polygons that form an object's surface, which means that if the surface moves or deforms the texture goes with it. This is a very convincing construct and is now the standard 'realistic' effect in CGI. You could argue it is today's equivalent of 'trompe-l'œil' painting; the English translation of which would be; “deceive the eye”, indeed its definition is 'the representation of an object with such verisimilitude as to deceive the viewer concerning the material reality of the object'. Therefore 'deception' is central to the textual mapping CGI effect. Plato warned people to be very wary of this state of affairs, he stated over 2,000 years ago that as art imitates physical things, creating in effect a copy of a copy, it leads us further and further away from truth and into a world of illusion.

CGI surface illusion

Another problematic issue in relation to these illusions is 'point of view'. In perspective everything works fine, so long as you are at the exact spot that the perspective is designed to be seen from. This issue was unpicked in detail by Panofsky, who highlighted the fact that perspective was not just a technical means to render space in a convincing way, but that it was a symbolic form. It reinforces a particular way of looking at the world, and I would argue makes the world 'commodifiable' by making objects and buildings appear graspable as things, a state totally at odds to an understanding of a world consisting of actions experienced as processes. 

A powerful illusion can be created of almost any form with a surface texture, in the case of the rooster above feathers and leather are convincingly rendered, making this fantasy cockerel appear to be very 'real'. 

We all know that fur feels soft, tree bark feels rough, and silk feels smooth, but also fur looks soft, tree bark looks rough, and silk looks smooth. This conjoined tactile/visual aspect of surface textural variation as Stephens & Hoffman (2016, p.257) pointed out, has long being used by artists and designers 'to evoke emotions and set moods'. Texture is therefore not just something that can create illusions of reality, it is essential to the development of forms that can stimulate emotion. 

Textures used by Stephens & Hoffman to test out aesthetic preference

It would seem in this case that touch and sight are again brought together in close proximity, our experience of textures being reinforced by a combination of perceptual stimuli. Synesthesia, the perceptual phenomenon in which the stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway, it has been argued, (Cytomic, 2002) leads to a much more heightened awareness of the perceived experience. 
Perception and feeling it would appear, are inextricably linked together. The qualia related to both experiences, I would argue reinforcing each other, because the qualia associated with emotional feeling developed as part of the interoception and associated body schema systems, would be generated at virtually the same time as the visual qualia entering the body from outside. These raw qualities of sensations, emotions and thoughts, although experienced privately, subjectively, and directly, are also what will eventually make up the building blocks from which all communication, both logical and emotive, will be effected. (Wolfe and Bell, 2007) A movement of chemical and electrical energy, is central to both perception and resultant action, the holistic nature of the process becoming more and more apparent as research into the processes associated with cognition advances. 

Computer generated textural surfaces developed from hand applied textures

In the image above certain aspects of body schemas have been used to both suggest the idea of the body as its own landscape, as well as being a place within which decisions are being made as to how the body 'thinks' and feels. Indeed it has been argued by Margaret Wilson, (2006, p. 211) that body schemas act as prediction devices, interacting with perception, cognition and behaviour in a variety of ways. These schemas can be thought of as copying devices and as such perhaps lie behind our interest in likeness or similarity as ways to develop meaning. In this way we return to metaphor as being integral to the development of our ideas. 

This close relationship between perception, illusion and emotional stimulus, was also something Plato commented on in relation to his worries about the power of art to effect people's emotional states, not only was illusion to be distrusted because it was not truthful, art's power to effect emotions, meant that for Plato illusion and emotional manipulation are often found together and this is something that we have seen to be more and more the case in this age of post truth politics, CGI and powerful media illusions. However as a process, the interrelationship between perception, illusion and emotional stimulus, would seem to be central to how we as humans devise ideas, so perhaps it is a problem deeply rooted in the very way we need to digest information. Copying, fiction and a tendency to find meaning in likeness all influencing our perceptual receptivity and responses to the world, so rather than like Plato trying to outlaw any art form that uses these tendencies, we should perhaps be seeking to observe how they operate and how we are prone to give effect and agency to perceptions that are as much inner constructions as they are responses to changing outer conditions.

Drawing and perception: the curved surface

To prove that it is not possible to draw and paint as the eye sees.

One of the first issues to confront anyone trying to draw what they are looking at is the conundrum of being a creature with two eyes, both of which operate as if they are at the centre of a sphere. As you can see from the drawing above, any vertical looked at by an observer is closer to the eyes at eye level and is further away from the eyes as it rises above or falls below eye level. This is exactly the same issue if you look to the right or left and is behind the classic drawing problem as was set for students on the foundation course at Leeds when I first began teaching. 


Students were asked to set themselves up in a situation similar to that in the drawing above. They would be looking at a floorboard or the line where a wall meets the floor, represented by the line AB. Using a ruler and plumb-line they would be asked to check that the line was at rightangles to them all along its full length. They would also be given string and chalk and be asked to measure the distance of the centre of the straight line from their fixed centre of vision, and then from that same point to positions A and B. They were then set the task of drawing this perceived situation as accurately as possible. Read Drawing a straight line and giron and fesspoint drawing to get a feel for the pedagogic history associated with these issues. 

The final drawings looked very like these drawings below and they reflected different levels of perceptual awareness. 
A continuous experience of looking at a straight line

The line AB appears continuous, and as students measured distance, most of them decided that the point nearest to them would also be the point on their drawing that would be nearest the bottom edge of their drawing paper. The dashed line CD often actually existed as a drawn line on the floor, because a student could use chalk and string to produce a semi-circle with themselves at the centre, and which would therefore in effect if drawn, be drawn as a straight line. An interesting reversal that some students would find very hard to grasp. 
A discontinuous experience of looking at a straight line

However some students produced drawings looking much more like the second one. They realised that between each measurement their body moved, if only slightly, and that each perception was a discrete event and that it was only in their imagination that the individual moments of perception were joined together as a line. This was in effect bringing in the issue of time in addition to that of relational space. Some students could never draw the line AB as anything else but a straight line. They knew from previous experience that it was straight, therefore they couldn't accept that what they were actually seeing was a curve. In effect the image schema they had in their head was so powerful that it would override any other evidence. 

I wanted to go back to these experiences because I am very aware that another member of the perceptual drawing research team, Mike Croft, has referred to these issues in relation to his own research into how to record a growing awareness of a perceptual event. See this earlier post when Mike was operating as a guest blogger. 

My particular interest in this is though political. As recent events have shown us, even given clear evidence to the contrary, if some people believe in a certain situation, they will continue to believe in that situation because if they were not to, it would destabilise their belief system. They literally cant see the situation in any other way. Perception is I would argue therefore tightly bound up with belief and the type of personality of the observer. 

Belief systems it would appear to me, are also in operation when we begin to look at the way 3D visualisations are developed. In Matthew Kaplan and Elaine Cohen's paper 'Producing Models From Drawings of Curved Surfaces', they state the following, 'Few sketch based modelling systems allow the artist to draw naturally. Typically, designers are forced to learn a set of drawing operators that are used as an interface to an underlying CAD system. Alternatively, previous methods that analyze existing drawings typically limit the type of drawings/models that can be reconstructed to a subset of models useful in CAD. The goal of this research is to allow the artist to draw as naturally as possible, placing minimal restrictions on the structure and process of the input drawing and the form of the output model.' (2006) The idea of what artists draw naturally, is reflected in the images we see at the end of the paper, it is presumed that artists draw in a very 'cliched' manner, that the old rules of perspective and consistent shading etc. are what artists are trying to work with. Drawing that questions perception, will it could be argued, very rarely be integrated into CGI visualisation systems. But there are some very interesting half way houses. 

The Oakes twins have been working for several years making drawings using devices designed to reflect the problem of curvature and the idea of vision being something that originates from a spherical experience of visual perception.

At first sight it would appear as if the twins have 'cracked it'. Their curved devices allow them to look at the world and record it from locations clearly within a spherical context. However if you look at how their images are then reconstructed from the drawings produced within the individual strips of vision, you can see that they are in fact still using the idea of a continuous link between all the elements of the drawing, like those foundation students who produced a continuous curve, the oscillation of constant checking, that moves back and forth from inner to outer experiences is not taken into account. Their drawings are though really interesting and in particular their method of drawing as a series of radiating centres that overlap each other to develop a surface, is a very interesting response to the problem of the knitting together of experiences into coherent wholes.

The Oakes twins are quoted as saying; “Our eyes are only able to gather the light rays that happen to be aimed straight toward them. Collectively, any group of light rays that happen to converge onto one’s pupil are, altogether, fanned out radially from the pupil, with each light ray traveling perpendicular to the surface of an implied sphere. The surrounding objects of the world may be irregular and varied, but perceptually we live neatly at the centre of a sphere of incoming photons that carry information about the irregular surround to our eyes.” Because of this, the brothers create images on concave surfaces, which they state “is in harmony with the shape of light rays and makes more sense than a flat picture plane.”

I'm not entirely convinced by this because it presumes the moment of perception can be located at a single static point, and this fixed point in my mind pulls the perceptual experience out of its ongoing process of renewal. However their approach does enrich the debate. 
The Oakes twins exhibition view

It has been a useful experience to revisit and reflect upon perception and how it shapes our thinking. It is central to our ability to make images that have a relationship with the world and how we perceive it, and at one time this used to be central to most visual arts practices, including my own, but over the years I have like many other artists been more influenced by conceptual developments rather than perceptual investigation. This experience has been a welcome reminder that whatever I make as an artist it is going to be experienced by others as a perceptual phenomena and if I am not dealing with my awareness of this, I won't have control of the situation. We shall see where this new research takes me.
