I bought 3 books from Amazon:
[FONT=verdana,arial,helvetica][SIZE=-1]"Understanding Exposure: How to Shoot Great Photographs with a Film or Digital Camera"[/SIZE][/FONT]
[SIZE=-1][FONT=verdana,arial,helvetica]Bryan Peterson; Paperback; £10.31[/FONT][/SIZE]
Im half way through this one, its great, really helpful and has large pictures so you can visualise what he is talking about.
[FONT=verdana,arial,helvetica][SIZE=-1]"Digital Photography Masterclass: Advanced Photographic and Image-manipulation Techniques for Creating Perfect Pictures"[/SIZE][/FONT]
[SIZE=-1][FONT=verdana,arial,helvetica]Tom Ang; Hardcover; £11.99[/FONT][/SIZE]
Going to start on this one after I have read Understanding Exposure. Some case studies in there and also covers basic post processing.
[FONT=verdana,arial,helvetica][SIZE=-1]"Mastering Your Digital SLR (revised edition): How to Get the Most Out of Your Digital Camera"[/SIZE][/FONT]
[SIZE=-1][FONT=verdana,arial,helvetica]Chris Weston; Hardcover; £12.48[/FONT][/SIZE]
I bought this one because I was reading it in a bookshop here and I liked reading about the basic operations of a DSLR, and it has some decent diagrams in there to explain DSLR operations, rather than just text. Its a non essential but I am really happy with the purchase.
