I'm a huge fan of Scott Kelby's series
The Digital Photography Book. The first book is my favorite intro book for digital photographers.
I just got the third book in the series. It's another great book. I have a huge reservation, however. Each book in the series is geared towards increasingly skilled and series photographers. This third book spends a lot space on studio shooting, which is probably outside the scope of most shooter's interests.
One of the things that I like about Scott's book is his candor. He doesn't shy away from comments that are out of fashion. For example, he advocates the use of UV filters for lens protection.
Another strength is that he leverages the web. In many places in the book, he sends you to a website where you can see setups, final pictures, etc. All of this could have been crammed into the book, but doing so would have significantly increased the size and price.
Kelby is best known for his Photoshop training. The book does a good job in guiding you towards what things should be done in camera and when it is easy to do things in post-production. Like most sensible people, he stresses trying to get things right before shooting rather than cleaning up later, but he's not a zealot about it.
Like all of his books, it is infused with his sense of humor. He's not really that funny, but he's not offensive either. He comes across as a pleasant jokester.
