I may be stepping in over my head here but I do not see how a camera/photographer can 'abstract' anything. At most the camera can 'isolate' but not take apart and put together in
another way as seems to be meant by abstract.

The pictures we see in the APUG galleries that are called abstract seem really to be a single, isolated segment of a larger subject.

I know painters and writers can abstract but can the photographer/artist?
