#Cityporn is currently covering Philadelphia. I’ll let you know when it moves on to something else. The submission guidelines:
Cityporn accepts and encourages submissions, but it is picky. It favors real representations rather than beautiful ones, lived images rather than postcard pictures. It wants to be the next best thing to being in the city itself. Hyper color-corrected pictures with magical sparkling skies are discouraged, as are arty shots whose subject can’t easily be discerned. You should provide as much context about a shot as possible. Submissions should credit the original author.
Non images are welcome and should capture or illustrate some vital essence of the city.
