I've recently made a few observation based on viewing the most "popular" or "liked" photos on different photo boards, Flickr, and 500px. First, these photos are amazing and inspiring as a photographer. The artistic and technical skills displayed are impressive. Secondly however, it seems the majority are shot or processed in a dark, gloomy, gritty manner with colors muted and flat. Subject matter also doesn't seem to matter. Landscapes, portraits, macro, nature display this "dark" influence. Has anybody else noticed this? If this is indeed true, has that always been the case with photography? I remember when I was getting back into photography 7,8 years ago, color and dynamic range seemed "the thing" with radioactive HDR images representing the extreme. Perhaps these things go in phases or perhaps it's a reflection of our overall mood, or perhaps it's my imagination.
