It’s like the joke about the Dalai Lama ordering a pizza: “Make me one with everything.”
The picture above is a detail of a detail. I copied a portion of Paul Cezanne’s Chateau Noir at the National Gallery of Art. (I posted that one recently.) This picture is a detail of that drawing (which portrays a detail of Cezanne’s painting).
Already this post is turning into Russian nesting dolls.
Anyway. I like looking at details of pictures (including — I don’t mind telling you — my own pictures). And for those who want to do abstract painting, you could find motifs for the abstractions by enlarging a small bit of some representational image.
What I like about the parts, though, is the way they reiterate whatever good things are happening in the whole. At least in a really well organized picture the parts will be doing on a smaller scale whatever the composition is doing on the large scale. It seems to me that this is true in the works of all the great masters.
So the lesson is — actually I’m not sure what the lesson is. Just be a great artist. There you go. Easy peasy.
