I find I promote film use the best when I am not on the internet but out shooting, carrying my little 5x7 folio of hand made prints. APUG is not what gets people looking at choosing film again, it is where they go once they decide to explore it, if they can even find the site, usually by word of mouth.
This site and especially the photos that reside on it are largely invisible to most of the world and I think that PE's citation of metrics is probably correct. Those who become re-engaged in the craft of using film usually have done so because they were inspired by something or someone, like an NYT Lens blog article, a showing of fine prints, seeing someone under the dark cloth or seeing better than usual work on flickr.
There are some spectacular images being made on the last three iterations of iPhones and like it or not, if they were printed to 16x20, their sheer impact would far outdistance a lot of the work being shown on this site. So this is what the reality is, the smartphone has readily taken the place of the SLR, compact or point and shoot as the cash cow of memories and you can be an old washed up codger all you want and say that they will lose their memories but that will not change what has happened or what will continue to happen to the availability and price of film.
Film use is super-niche and the market is still adjusting to that, never to be a super-market item ever again. So instead of bitching, maybe get some real prints into someone's hands for them to look at when you are out shooting....and no, sorry, not computer prints born of scans, they will not convince someone to use film like you think they will. For when it comes right down to it, the guy is going to say "but I get just as good a print from my iPhone 5S" and he will be right...
Getting off of here and out shooting and showing work is the only way to promote one of the best reasons to use film, not being on a computer..
Oh, and about the choice of name for this site, it is terrible, sounds like a "A-Pug", a dog, **really** piss poor when it comes to promoting film. Google filmphotography.com, not even in use although grossly overpriced, drop the last letter and it is a bargain so buy the damn URL and have it link back to this site, can you do that with MY money please?
Something, anything else to direct traffic to the site because the name is horrid in terms of finding the site Sean…not one single pro or very few amateurs I have encountered have even heard of it.
