For those that want to learn more about taking good digital photos, I found a great on-line book you might want to check out. Here is a selection from the preface:
A great photograph begins when you recognize a great scene or subject. But recognizing a great opportunity isn't enough to capture it; you also have to be prepared. A large part of being prepared involves understanding your camera well enough to capture what you see the way you want to interpret it. Getting you prepared to see and capture great photographs is what this book is all about. It doesn't matter if you are taking pictures for business or pleasure, there's a lot here to help you get better results and more satisfaction from your photography. To get better, and possibly even great photographs, you need to understand both concepts and procedures; the "whys" and "hows" of photography.Check the rest of the book at http://www.shortcourses.com/use/ They have a lot of beginner and more advanced tips.
