...I think this thread should just be shut down and people should read Crisis Of The Real and other great books (that as pointed out already) that have tackled the issue of "photography as art". The philosophy of art and photography won't be summed up in 400 pages on RFF. I'm all for great discussion online and elsewhere, but a smug comment (regardless of your entitlement to say whatever you want online) will only invite crude, reactionary and emotional responses on this forum. Of course, there are very intelligent and well-qualified opinions on this forum, but to sift through all the gibberish to get to them is more time consuming than reading the research, essays and articles from people who have dedicated their entire lives to this topic.
I'm not one to appeal to authority on the matter, but cut through the wannabe intellectuals and get straight to the source and read something of substance on the issue from someone who is an "expert" on the subject. Online, you will get a lot of people who will hype themselves up, get their egos involved and try to persuade others that their way of thinking is the only way to think. Read, educate yourself and incorporate that conversation in a forum that is more productive than here. Of course you can ask "is photography art?" on RFF and you will likely get some good answers, but the crap you have to sift through first isn't worth the effort.
