I never retouch a sketch: I take a canvas the same size, as I may change the composition somewhat. But I always strive to give the same feeling, while carrying it on further.

Everything is reduced to a mere sensation of the retina, but one which destroys all tranquility of surface and contour. Objects are differentiated only by the luminosity that is given them.
