Photo usage in a book

This is a similar question to Greg Lessard's. My sister-in-law has been writing a training manual for a new dog game ad I have been illustrating it. She has been selling it on her web site, but now a publisher of dog books to print a run of it that could be sold in such places as Amazon and Barnes and Noble. She doesn't have all the information yet, but I was wondering what I should ask for the pictures. It will be more than one or two in the book as I am the primary photographer she is using. This has been a learning experience for both of us and we would both like it to be financial rewarding, even if the reward is rather small. Any help would be gratefully accepted. Please use my email if you think that they will come after us for price fixing. Thanks.

I sincerely doubt you'd get much of a payment, if any at all, from the publisher since it's a completed work. You might work out a "side" agreement with your sister for a percentage of sales. When I've done work to illustrate books, it's always been on contract before publication rather than per photo as a percentage of sales. Photos individually submitted to books that are essentially "anthologies" of multiple photographers' work have been paid at rates based on % of page coverage with extra for front and back cover, title page and centertruck if that's in the format. Those rates are pretty well set ahead of time, and you can choose to submit or not.

Thanks Hank. I was hoping for a more optimistic answer, but I was not really expecting one. The publisher has indicated that he will a percentage of sales and I will have to work with her from there.
