Thanks Karen. Interesting that you mention the difference between the single image and the image as part of a group of shots. I've recently been reading Michael Freeman's latest book, The Photographer's Vision, and he discusses the often overlooked role of the means of display in shaping the photographer's approach to the image, something I myself had largely overlooked.
I had photographed in this neighhourhood previously just because it was nearby. As I expanded my collection of shots from the area I consciously decided to make regular visits to explore more of the area and to revisit bits of it I had already seen. When I shoot now, I am conscious of what I have previously shot - conscious sometimes in an unconscious way, if that makes sense - and am indeed shooting to add to an existing collection of images.
I wonder in the light of other ongoing discussions about responses to images if that isn't also true for others. Perhaps images that we feel are not sufficiently 'recognised' don't strike the viewer the same way because they are being viewed in isolation from a larger body of work that each of us creates over time, deliberately or otherwise.
