Pay attention
When a professional sports photographer, whose photos regularly get published by ESPN on their website and magazine, starts a blog - you pay attention.
Check out Mark J. Rebilas’ blog, where he regularly posts some crazy awesome sports photos and talks in wonderfully entertaining detail about the process by which he got them. His latest entry on “light pockets” is just too cool. This is the real deal - great photog, and real blogging, not just photo posts sans text. Go.
