I didn't want a model in the room for three or four months. It would drive me crazy, drive them crazy. But also, they gain weight, they lose weight, their hair gets long, they cut it short, they're awake, they're asleep. And a painting becomes the mean average of all those conditions. I simply looked at photography as a way to jot down the information.
