Kittens sit high on the moral index, but homeless people with puppies are the best evidence of the moral character of the photographer. A homeless person with a lurcher pup on piece of string in a shopping precinct playing a tin whistle while a well dressed lady ignores them shows,
correct use of contrast
sharpness in lines per millimetre
separation between subject and background
the ability to photograph on brief
a social conscience
Absolute moral good requires vignetting, the use of sepia and a watermark across the middle to identify the photographer. None of which an abstract Autochrome delivers on, proving it to be a work of moral degeneracy, or worse, lacking corner to corner sharpness.
hmm this is interesting.
I have just returned from the Don McCullin retrospective at Hauser & Wirth, and while he seems to have quite a lot of pictures of poor brown people being unhappy - which presumably is on all fours with your "homeless person with a dog on a bit of string" criterion -- I have to report that his shadow detail leaves a great deal to be desired indeed!
(I left a note in the visitors' book to the effect that he could join APUG and get some advice on how to properly test and expose film)
