I just bought a nice digital SLR camera (Canon EOS 20D, with EF-S 17-85mm f/4-5.6 IS USM lens). This is my first SLR camera; before, I have only had point-and-shoot compacts.
Although the 20D is capable of being used as a very sophisticated point-and-shoot, I would like to get the most out of it.
Does anybody have a recommendation for a good photography book (or set of complementary books) on photography (esp. tailored to digital photography)?
I already have this book, which is essentially a user's guide on steroids for this particular camera.
I would like a book that shows, for example, the effects of different lenses, aperature, speed, etc, on the same shot.
If anybody out there is an amateur astronomer, a (digital) photography equivalent of this book would be most helpful, as well.
