Formfreu.de has been a favorite photo blog of ours for a long time. Started by Markus Haub and Thomas Sälzle in 2007, they are able to consistently create evocative content on subjects from culture to automobiles. Strong color and composition, emotion, irony and humor are immediately evident in their work.
Be sure to set some time aside to check them out. Careful, it can become addictive.
