Good Books 

There's an awful lot of stuff to learn about when it comes to computer graphics. And a good book by someone who knows what they are talking about can be a big help.
The ones below are all ones that I've read and think are particularly good. Unless otherwise stated, none of these require any specific 3D software. They all teach general techniques and principles which you can then use in pretty much any modern 3D package. I've provided links to the books at Amazon US and UK in each case.

[digital] Lighting & Rendering - Jeremy Birn

cover

Lots of good stuff about lighting in computer graphics compared with the real world, why rendering in layers is a really good idea, and why you should never use the standard 'ambient' light in your renderer!

Modelling Digital Dinosaurs - Ken Brilliant

cover

A good book for learning organic modelling techniques using subdivision surfaces. The book leads you step by step through the modelling and texturing of five increasingly complex dinosaurs. An interesting and varied set of animals is used, and different techniques are introduced with each model. The book does not assume any particular modelling software - the techniques are generally applicable.

The Art and Science of Digital Compositing - Ron Brinkmann

cover

A good readable introduction to the technical side of compositing. This book doesn't tell you how to use a piece of software, it tells you what you need to know to actually understand compositing. Includes image representation, gamma, premultiplication, image formats, etc. Technical, but not overly so.
