I don't know about anybody else... I've always avoided titling my photographs. It seems silly and redundant. Shouldn't the photograph speak for itself? I display a photograph and expect the viewer to interpret it however they choose. My impressions of the photograph are pretty much irrelevant to this viewer. Does a title attempt to impose my interpretation on the viewer? For an example, a picture of a cloud is clearly a cloud and nothing else. If I had to title it then I'd call it 'Cloud' or maybe 'Rain Cloud' A title like '...waiting to get soaked' or some other cutesy/cheesy title would merely demean the work. Do you title your photographs? If so, what is your motivation? What are you trying to convey that the photograph doesn't already convey?
