Last night as I looked at the model on a low cot on the floor, lit from overhead, all I could see was the light of her body. How am I ever going to find form? Well, it took awhile,but gradually my eye began to see the plane changes. I had to darken the background, which was a very light grey floor, 2 times. So you can't paint what your head tells you you see, but what you actually see. Ah, to discern these subtle nuances is the challenge. Meanwhile, someone in the building was using the WRONG kind of thinner, and we all left feeling woozey from the fumes. Into the Boston hot summer night air and we're heading home,happy night painting.
