Accessible by Uwe Eischens Incredibly well processed, often surreally beautiful landscape and intimate landscape shots. His pictures often seem to glow.
Cornforth Images Some of the best landscape and nature photography around, in my opinion.
Darwin Wiggett A cross between a photography blog and a photoblog, but still more space given to images than text. Great work from Darwin himself as well as many other featured photographers.
Eli Reinholdtsen GREAT reflection images, that's her specialty, but also some wonderful street work. I find her blog a good reminder that everything doesn't have to be perfect or straight to be interesting and beautiful.
Tafari's Mindspill Sometimes controversial, always entertaining, and some good photos as well. I particularly enjoy his work with flowers.
The Still Image With Crash Taylor I really like the premise of this blog, which is to take great photos from all kinds of photographers and have the photographers themselves speak about the process of making the image. My only beef with it is that Crash always has one of his images in the post as well, and frankly they're usually not as good or as interesting. But that's probably being a bit picky.
Anyway, please feel free to leave your favorite photo blogs in the comments! (Not that my Google Reader needs to subscribe to anything else, quite the opposite!)
