NOTE: sorry for the rather ridiculous length of this response… I guess am just really excited about this whole process that I have been working on… but in my defense, the question DID ask HOW I visualized my art… it never said to answer in 500 words or less…
I have actually been trying something rather interesting along these lines lately. Up till now I just started drawing with some sort of idea in mind and then let it take me where it will… and honestly, it usually comes out just fine. Unfortunately I have been finding that the result simply does not give me the control over the final product that I would like to have. Further, it doesn’t give me nearly the detail that I would be able to include if I was drawing from life.
Lately, I have been trying to create a process through which I might be able to draw from observation within my head. By utilizing a combination of meditation and self hypnosis, I put myself into a dream like state while still maintaining full control of my hands (so that I can draw). once Inside, I have full lucid control over the dream world, so I set up things like I want them to be and then simply copy what I see onto paper.
For example:
I did a painting recently where I wanted to show a person that had just smacked into the canvas with some speed, as if it were a window. I was finding it pretty hard to think of what the pose would look like and how the flesh would spread where it contacted the glass. I therefore set up a place in my dream world where I could throw people off of a high dive so that they would smack into a glass table below. I would just wait for the falling people and draw the impression that their bodies made on the glass. It took a few tries, but eventually I got something that looked pretty much like what I was after, so I did a sketch and then proceeded with the painting.
It may seem a little weird that this system would help me, because, presumably, I cannot see anything by using this method that my brain did not already know. While this is admittedly true, I think it might be that our brains are not very good at thinking in 2 dimensions, so they to try pretty hard to compose an image straight onto paper. On the other hand, the brain is incredibly good at thinking in four dimensions… it has to be, because everything that we interact with everyday is four dimensional. The subconscious brain does millions of tiny calculations all the time to keep moving through this 4d world, and has gotten quite good at it. That is why it is so hard to make believable animation… the brain is just too picky.
When I am using this method of visualization, I let my subconscious take care of things like movement, perspective, lighting, physics, and so on. It runs a simulation of the real world and everything in it behaves like it should. If you make a human, they will usually move pretty much like a human, and as long as you know your anatomy, they can be quite realistic looking and you can put them in any pose that you want.(although some of the musculature will undoubtedly react incorrectly) The functional result of all this is that you can set things up vividly and accurately within your mind by simply willing it to be so, while still maintaining the plasticity to change things around infinitely.
Any object that you create will exist in 4 dimensions, and I have found that the brain will automatically account for different viewing positions. If I draw a fruit still life, and then walk to 90 degrees, and draw it again, the brain will automatically interpret the three dimensional movement and the resulting still life will look like the same subject seen from a different angle. (you have to concentrate on the fruit while you are moving though, or else a couple of the fruit are liable to switch places… but more on that later)
The other neat thing that I have found is that at any point you can let your subconscious mind slip into full dream mode, and guide the action… often with very strange outcomes. this makes the technique ideal for brainstorming ideas.
There are some major downsides to this method though, first off, it is extremely hard to initiate the proper mental state. it basically consists of giving yourself a hypnotic suggestion that you (your conscious mind) are entering into your dream, but you can still control you arms. it is kind of like sleepwalking… but with arms. The mind really doesn’t like doing this, and I have found that sometimes, I simply cannot do it, no matter how hard or long I try.
Also, once you are in the right mental state, it is really hard to maintain for very long. Just like lucid dreaming, as soon as you become too aware of things, your conscious mind will try “wake up” and you will have to go back to square one. unfortunately, due to the fact that you are not 100% in the dream world, (you are still conscious enough to manipulate your hands) this eventuality is made all the more likely.
What I usually do to get back into the dream state is envision a series of doors that are made of random materials (not materials that you think of, just let your subconscious dreg something up.) I then try to think of the “key” to that door… the thing that I could do to allow myself through the door. I try to think of the most interesting and creative “key” that I can imagine and then try to envision what it would look like. I use each door passed as a hypnotic suggestion to bring me deeper into the trance state, while the visuals and problem solving serve to distract my conscious mind and open me back up to the lucid dreaming state.
The other minor bummer that I have run into is the lack of feedback when you are drawing. There is no paper and no pencil in the simulated world, so you basically have to do a blind drawing… sure, you could set up your composition and then draw it from memory while not in the dream… but that kind of defeats the point. you would be drawing from memory, not “observation”.
To remedy this problem, I have tried to link arm movements with some sort of visual feedback within the dream, (like a dot or cursor or something,) but I have had very little luck… mostly because it takes concentration to update the cursor position in time with my arm movement, and doing so tends to pull me out of the trance.
Perhaps the worst problem is that it is really hard to keep yourself in control of your surroundings, because you are functionally in a dream, and there are some pretty weird things that can happen. First off, object permanence is pretty much nonexistent, this is a real hard one to get used to. when you look at an object and then look away, the object seizes to be. When you look back, your brain will reconstruct the image from memory and will not necessarily come up with the same thing unless you take very careful note. this is important to remember when you have to stop in the middle of setting up a composition, and you need to “save your work” so to speak. the last thing that you have to do is examine the image and consciously note all the detail of the image that you want to preserve, because when the brain accesses the memory, it will reconstruct the scene with only those details that you specifically make note of.
Also, to aid in recall of the image, I would suggest putting in some sort of memory aid that will facilitate the recall of the scene as you left it. I use pieces of colored yarn, which I tie to the “room” containing the composition and then lead out through all the aforementioned doors. it seems to offer a pretty good aid to recall, as long as you can remember how many strings you have and what colors they are.
Dreams also have the nasty tendency to switch channels suddenly and without warning, and unless you are extremely disciplined, your thoughts will tend to wander at least somewhat. if your mind wanders too much, or your background/parallel thoughts get too loud, the dream will almost certainly respond by switching to something else, trashing whatever you were working on. it is prudent to destroy background thoughts as soon as you notice them. when I notice this happening, I usually try to focus on every possible detail of the closest object to drive out the other thoughts.
Also, you have to realize that just because you see something does not necessarily mean that it actually looks like anything. you are not actually in the world, and often you can mistakenly try to draw the “concept” of an object rather than a defined version of that object… although it will look at a casual glance like the object itself. if you start to draw it, you will likely come up with something that looks nothing like what you are intending. To be sure, look for details like tufts of hair or spots or something… the act of looking will undoubtedly make them appear, but this is ok because it at least defines that object’s unique identity, and avoids the risk of drawing a symbolic representation.
