One does not think during creative work, any more than one thinks when driving a car. But one has a background of years - learning, unlearning, success, failure, dreaming, thinking, experience, all this - then the moment of creation, the focusing of all into the moment. So I can make 'without thought,' fifteen carefully considered negatives, one every fifteen minutes, given material with as many possibilities. But there is all the eyes have seen in this life to influence me.
