I can't stress enough how important it is, if you are interested at all in painting, to look and to look a great deal at painting. There is no other way to find out about painting. After looking comes imitating. In my own case it was at first largely a technical immersion. How did Kline put down that color? Why did Guston leave the canvas bare at the edges? Why did H. Frankenthaler used unsized canvas. And so on.
