Seeing the Illusion
The human brain is an absolutely fascinating organ. Science has yet to even touch the surface of understanding is capabilities. One of the most incredible things it does is cause us to see things that aren’t really there. The brain does not like a void. If something is missing and our brains think it should be there, then it will make it up for us so that we can see it. It tries to fill in the empty space with what it thinks should be there. There are many optical illusion books and websites that demonstrate this.
These optical illusions demonstrate two very important points about art. The first point is that art itself is an optical illusion. Your job as an artist is to create an image that will cause the viewers’ brains to fill in the gaps and make something complete. You are not working in three dimensions; you are working in two dimensions. But when your viewers look at your art their brains will force them to see the art as three dimensional. They will not see the fact that what you have actually done is take a nice clean piece of paper and creatively spread dirt all over it. They will see actual objects.
The second point that optical illusions demonstrates is that we don’t always see what we think we are seeing. lightandmagic That is the big issue here. If you want to create the illusion for your viewers then you must be able to see the reality behind all things, not just what your own brain tells you exists.
Seeing the Color
Take a look at a rose, for example. At first blush you would think that it is pink. Because of that you might want to draw or paint it pink. But look closer and you will see that it is filled with many shades of pinks, yellows, oranges, lavenders and whites. Those are the colors that you will need to use in your painting if you are going to trick your viewers into thinking they are looking at a real rose.
Look closely at your subjects and analyze them. Everything you need to draw them is right there, don’t let your brain convince you that you are seeing something else.
Seeing the Light
Did you know that you do not see objects? If you look at a car driving down the street or your best friend sitting across from you at the coffee shop, you aren’t really seeing them. What you are seeing is the light that is reflected off of them. Eyes process light. It isn’t until we touch an object that we actually experience the object itself. This is a very important concept to keep in mind when you are drawing. If you try to draw an object then your brain will try to force you to draw that object they way it thinks that object should be. If instead you focus on drawing light and shadow, you will have much better results.
Take a look at a billiard ball. Instead of looking at the object, look at the light. There are three types of light that I want to point out here: highlight, shadow and reflective light. All three of these types of light are very important in creating photo-realistic drawings.
The highlight is going to be the lightest part of your image. This is where the most intense light reflects off of the object. Never skimp on the highlight but don’t overdo it either. Try to recreate the highlight exactly the way you see it in the original image.
The shadow is always the direct result of the source light. Keep that in mind when drawing. Shadows are simply areas of less light because there is either something blocking the source light or the area is farther away from the source light.
Most people fully understand highlight and shadow, but the true magic of light comes from reflective light. Reflective light is the light that bounces off of other objects and reflects off of your subject. In the example of the billiard ball, the surrounding light bounces off of the surface it is sitting on and is then reflected off of the underside of the subject. Recognizing reflective light is very important. You see it everywhere, but your brain tries to block it out. In many cases, subjects have such a reflective surface that reflective light is defined to the point that you can actually see other objects reflected from your subject. If you want to take your art work to serious levels of realism, you must learn to see those reflections and include them in your final piece. The most important thing to take away from this is that in order to realistically draw something you have to be able to realistically see it. You have to train your brain to forget the things that seem to be missing and focus on the reality of how the light is reflected.
