Colored Pencil week 5 or maybe it's 6

Tonight in colored pencil we made apples. It's the kind of exercise I dread, trying to actually create on papaer something resembling the object in front of me. But an apple afterall is just a circle with a stem. It's the light, shadow and lines that create the illusion of sphereness. I don't have a natural instinct about how light hits an object and where the highlights should be placed and in fact I accidently colored over one of my light spots with a dark red. But layering the yellow, red, orange, brown and green in curves across the circle along with a dark spot for the stem indentation I came out with something that one may consider looks somewhat like an apple. When the class all put our pictures at the front of the room again everybody's was very different, some red pumpkin looking, some more yellow, some a rainbow but all clearly recognizable as apples. Which brings up yet another question how does a person process all these very different images as the same object? If these images were fed into a computer would the machine be able to recognize them as the same type of object. Part of what makes each person unique is that we can each hold a different image of an apple is in our mind. Then maybe what binds us all together is being able to recognize an apple as an apple even when it is someone else's vision of what an apple is.
