content: Some are from National Geographic, most are from 500.px. Other sources are Reddit, Pinterest, even Tumblr or Facebook. Looking through Instagram feed points me in the right direction sometimes. I try to post source where I can and it can turn into quite a hunt. Sometimes I find a name of the photographer and post directly from their site. I try to link to give credit to the photographer and to facilitate buying a print if somebody would be so inclined (I mean, these people live off selling their photos). A dilemma occurs when I find a picture I find really beautiful, but cannot find the author at all.
