There are three photography-related articles I want to mention, two of which were penned by Mr. Yours Truly.
Yesterday I posted two new book reviews on the Photography Articles page. While they're not about photo books per se, both are relevant to photography as a hobby and a business. The first covers National Geographic's Driving Guides to America, which can be used as a reference for the traveling shutterbug; the second is about Nolo's Patent, Copyright & Trademark, a valuable resource for anyone who does any business with intellectual property.
The third article is one I did not write and that does not even appear on this website. But I found it interesting, so figured I'd pass it along. "Tips for Underwater Photography" is about ... go ahead and guess. By Dan Richards, the PopPhoto.com article covers the technique and history of the work of underwater photographer Mark Snyder.
