One of the most helpful books that I've purchased in the last year is this book - Wedding and Portrait Photographers' Legal Handbook by Norman Phillips and Christopher S. Nudo. Inside you'll find gobs of different forms for use in a photography business -- or even just sample model releases for both adults and children if you are a hobbyist with editorial aspirations of any type. The book comes with the ability to download sample forms for use in your photography business. I bought my copy from Amazon.com for under $25 -- a real bargain considering the protection that legal forms offer photographers these days!
