Here are a few photographer blogs, and I know that there are lots of them out there - this is just a few. Gallery Artists Susan Burnstine and Aline Smithson have great blogs on photography, with musings of their own, as well as lauding kudos to artists they enjoy. Our own Joe Holmes has his daily image posted, There is Jen Beckman's blog, Jorg Colberg's take, Jim Casper at Lens Culture, an how we miss Alec Soth's daily musings. Another don't miss is Edward Winkleman. Have you seen i heart photograph?
You can literally spend all day getting lost in art from the comfort of your chair. Have a good time.
