I've been asked a few times for the list of books i'd recommend, so here they all are in one place. They're about weddings, photoshop, and photography in general. I'll update this occasionally as I find new books that I think are useful. NB: I get credit from Amazon if anyone clicks these links then buys a book, which I will donate to POTN.
The Best of Wedding Photojournalism. Excellent book with a viewpoint photographers should know about.
The Art of Wedding Photography: Professional Techniques with Style. Not bad, not my favorite wedding book. A bit outdated with respect to technology.
Scott Smiths' Wedding Book. An interesting book with an interesting viewpoint from a fantastic photographer.
Group Portrait Photography Handbook. Very handy for people new to posing groups, or people who want to make more interesting groups. It won't tell you how to take group photos like Toogy, but it will help.
Al Jacobs Wedding Book. (Free PDF)
Posing for Portrait Photography: A Head-to-Toe Guide. Brilliant book, best i've seen on posing principles. Not strictly about weddings but very very useful.
Digital Wedding Photography, by Paul Gero. A good introduction and starter book.
Scott Kelby Photoshop CS4 for Digital Photographers. An update to an excellent book
Photoshop Elements 6 for Digital Photographers - Scott Kelby.
Real World Raw CS5. Invaluable for anyone who works with RAW, no matter what software they use.
Real World Camera Raw with Adobe Photoshop CS3. A no doubt good update for the brilliant CS2 version i've read. Invaluable - workflow is one of the keys to making a wedding photography business work. This book helps with that. So does this thread.
Real World Color Management, Second Edition. Invaluable information for anyone who wants to use anything other than sRgb. It's quite technical, but color mangaement's a technical subject.
Amazon.com: Color Management for Photographers: Hands on Techniques for Photoshop Users. This was recommended to me, i've not read it.
Light - Science and Magic : An Introduction to Photographic Lighting. A briliant but technical book about photographing difficult things like glass, metals, and artwork.
The DAM Book. Digital Asset Management for photographers. See also The DAM Book Website.
Master Lighting Guide for Portrait Photographers. Pretty handy.
Understanding Exposure. A highly recommended book for anyone who needs to understand the basics.
Studio Lighting Guide by Scott Smith. Best studio lighting book i've found for the beginner.
