In the short period that I have been on APUG I have been awestruck by the talent to which I am exposed. I believe your work is emotionally charged and should be shown.
I think you are right that there is a reluctance to show documentary photographers at galleries. I recall an interview of Steve McCurry where he dismissed the notion that his photographs were art. But in any event whether somebody considers documentary work to be art or not, I think some photographers have the ability to transcend time, and when an image can stand alone like that for years and still have an emotional resonance, then I think it’s worth studying and worth being exhibited.
That’s my two cents from a novice. I am already glad I discovered this forum. Thanks for sharing you work and contributing your thoughts.
