Well this is a fun idea. Ever want to ask a studly National Geographic photographer for some picture-taking advice? Now you can, thanks to the new web site Pix Boom Ba. The ridiculously named URL should give you an idea of some of the charm of this photo tips site, and that’s the fact that the guru photographers involved—Bob Caputo and Cary Wolinski—are having fun while answering questions and offering photographic advice. With so many online resources geared to teaching photographic basics via blog, text and video (as this site also does), it’s great to see someone putting effort into making photo tips entertaining too. And that’s something this site does better than almost any other.
