An artist must possess Nature. He must identify himself with her rhythm, by efforts that will prepare the mastery which will later enable him to express himself in his own language.
In the beginning you must subject yourself to the influence of nature. You must be able to walk firmly on the ground before you start walking on a tightrope.
A picture must possess a real power to generate light and for a long time now I've been conscious of expressing myself through light or rather in light.
An artist must never be a prisoner. Prisoner? An artist should never be a prisoner of himself, prisoner of style, prisoner of reputation, prisoner of success, etc.
Exactitude is not truth.
