I won't pull any punches here. I very much dislike post processing of this kind. It is both pretentious and crude. It's an attempt to add a false quality to the situation implying actual difficulty in obtaining the image by use of extremes of film capability and processing. I used to struggle with those photographic materials and chemicals on a daily basis. Decades ago we did everything we could to minimize the technical difficulties of the materials. Today's computer simulation of film grain, lack of resolution and developer fog to imply artistic qualities leaves me quite cold.
As for the subject matter, unless this is an image intended to somehow contribute funds to this fellow or others in his situation, or otherwise help him directly, it is disturbing, if not insulting. To use his misfortune only to bring attention to one's photographic efforts is unjustifiable.
I don't mean to be confrontational, but this kind of image treads on ethical boundaries that all photographers need to heed.
