There is another interesting issue that came up in a thread (
Testing the Waters).
Although these images are cropped so that they are straight, according to a cropped off horizon, to me they look slightly rotated as they are presented due to the actual real slant of the beach.
In this case, should the maker persist in reality, keeping the 'real' slant in even though it may seem to be an intrusive technical defect to the unknowing viewer or should the picture be edited so that the view is most
normal (although actually unreal)?
