during the days of film exposing, there was also a controversy to grade photography as art. a painter paints with his mind with the help of colours and brush or other medium. while the notion was that since a photograph is passed thro many mechanical processes and the pictured is captured by camera, the photography is not relevant to be treated as art. however, after processing of the film many juggleries were done in the darkroom to give shape to the photograph as an art work. this was a successful technique and also during exposing of portraits, scenery, wildlife, nature, etc. without applying any darkroom technique, these photographs were master-class and not far away from the term "ART". the thing was that, that making a master photograph, the technique of human mind was involved and photographs compelled the critiques to realise the photography as Art. in variation also the word Art covers a vast range of subjects, so it was just a futile fight to term photography as Art. yousuf karsh, h.c bresson and other big names were the dignity of photography and what they produced is no less than the other art forms. besides art is immortal, and u fight for useless criticism of what is art and what is not. only the difference is that the ways of production are different, and the mind is pleased to view it. (these are my view relating to before oncoming of the digital photography and more can be written on this because of the obvious reasons). thanks.
