55. Internet K-Hole
Previously hosted on Blogger where it earned a bit of a reputation for its astonishingly long posts of found imagery and occasional grot from around the 1980s, the Internet K-Hole moved to Tumblr a couple of years ago. Tumblr's limit of 20 images per post lessens its impact a bit, but on the plus side it's updated a lot more regularly and still gets unexpectedly fruity and NSFW.
Photojojo, the store that sells gear for the modern photographer, also run this cool Tumblr blog, which shows off cool photography related projects.
If you're tired of looking at generic photography sites then Photojojo is definitely worth taking a look at. The team manage to find some of the weirdest and most wonderful work from around the world, so you're sure to find some ideas on how to really stretch your imagination.
The official Tumblr home of the Lomographic Society International is packed with stunning Lomographic snapshots. Have a scroll for some instant inspiration – and you can submit your own Lomographs too.
58. Megan McIsaac
This is the photo journal of professional photographer Megan Kathleen McIsaac, and showcases Megan's work and life as a photographer.
There are no tiny, watermarked photos here, with all the pics presented in a large enough format to appreciate the skill that's gone into their creation. The minimalist theme really enables Megan's work to jump off the screen. It's a great example of what can be achieved with Tumblr.
Ann Street Studio is the Tumblr of NYC-based photographer Jamie Beck and Kevin Berg. Beck is a great photographer, and you'll find a selection of her work here. You'll also find some really inspiring cinemagraphs on her site, with good reason, because Jamie was the co-founder of the whole cinemagraph movement.
