Everyone wants to get as much exposure for his photos as possible. To achieve this, one of the most obvious decision is to put the photo on a community dedicated to photographers. So, I want to hear which experiences you made with these communities. Maybe someone can find a new community through this thread, or we can find each other in the communities (please post links to your profiles if you want - mine are in my signature). As I'm just at writing a post anyway, I'll begin: I currently use Flickr, 500px and 1x. First and foremost, Flickr, as the worlds largest photo community, is an obvious choice. It serves as free online backup with its 1 TB of free storage and has some amazing photographers. Furthermore, there are some interesting groups with easy to use forums and some nice ideas. The problem? With 1 TB of storage and no limit to upload photos there is obviously a LOT of crap on there. They try to solve this by only showing you photos of your contacts on the start screen, and many groups are curated, but you'll still see more bad or boring photos than on most other platforms of this type. 500px - the place people run when they don't like Flickr. The quality level is much higher, but there is practically no sense of community there. No way to interact with groups of people, and the blogging features are meaningless as no one will ever look into the blog. I use it mainly for quickly browsing through photos of my favorite photogs. 1x has the highest quality level. I mean, it's insanely high. I don't have many photos there, but still, not a single one was good enough yet to be published on their front page. The concept of the community curating images is interesting, and the free premium account for top curators is encouraging. The community has extremely high expectations for photos, but they always criticize in a kind and helpful manner. Posting photos to critique or curating is optional btw., so you don't have to receive critique if you don't want to. The groups and forums are only half-baked, unfortunately, with clunky interfaces and no innovative features. 1x is a great place to get fast feedback on how well others like your photo with the curation feature, and a great way to learn on how you can improve with the critique section. The problem is, like I said earlier, the quality level is very high, so beginners won't have any fun there. Sites I don't like: deviantart (too many graphic artworks and too few photographs), Photobucket (doesn't seem to do anything right), fotocommunity.de (unfriendly community) and Blipfoto (the interface is too weird and the photo-a-day concept never really was mine). Now is your turn - please tell us what you experienced with photo communities!
