I would suggest picking up a copy of Bryan Peterson's excellent "Understanding Exposure" and reading it. Once you understand this, you're pretty much set.

I think those books should have the main info. But the basics of how the picture is made should be readily available in google also. Don't worry, we all have been beginners. Remember that the lens are more important than camera and photographer is most important. Composition and light make the picture. Just take a lot of pictures and don't worry if they don't look good, most photographers take a lot of pictures and only show the best. It's important to take pictures ;)

Hi and congrats. I just purchased my new cam about 2 weeks ago. It was recommended that I read this book and I have to say that it's a life saver for anyone with anew dslr. I highly recommend it:

When I first started with my G7 I was a complete beginner as well. I totally recommend this book. It's a super easy read and will help you immensely.
