Gerhard Richter (b. 1932)

"A picture like this is painted in different layers, separated by intervals of time. The first layer mostly represents the background, which has a photographic, illusionistic look to it, though done without using a photograph. This first, smooth, soft-edged paint surface is like a finished picture; but after a while I decide that I understand it or have seen enough of it, and in the next stage of painting I partly destroy it, partly add to it; and so it goes on at intervals, till there is nothing more to do and the picture is finished. By then it is a Something which I understand in the same way it confronts me, as both incomprehensible and self-sufficient. An attempt to jump over my own shadow...
"At that stage the whole thing looks very spontaneous. But in between there are usually long intervals of time, and those destroy a mood. It is a highly planned kind of spntaneity"
