I fully agree with John on a camera as an 'abtracting device' - a photograph ALWAYS removes something from it's original context, IMO. However - I think that "abstract expressionism" is a bit different than this in intent. To suggest otherwise would, IMO, be a misunderstanding of it. The word "abstract" is an adverb of "expressionism". So - the idea is about "isolating gestures" the way I see it at least.
