Don recently mentioned that he was playing with fill flash, so I thought I’d post the best online photo site I’ve read in a long time, Strobist.
It’s a blog, but has a lot of tutorial from the owner, who is an editorial photog for the Baltimore Sun. It’s a really great resource. Make sure to peruse the Lighting 101 links. It’s all about using off-camera strobes to light photos. I haven’t done the tuts myself, but I’d love to when I get some time.
