I subscribe to an e-newsletter that lets me know about Digital Photography School's web site updates. Today I got one that sounded like it might be interesting to some of us who haven't yet mastered light (or, for me, haven't even got the basics down, let alone 'mastered' it!!! :O). Hard to know how good this is, but it sounds interesting and it's 25% off right now, so I thought I'd pass the info along. The book is called "Natural Light: Mastering a Photographer's Most Powerful Tool". Just click on the title to read more about it. I'm not sure if I will get it or not, as I need to check with DH, but I would like to!
