Typical Remuneration for Photo in a Textbook?

Thank you, Astrostu! I try my best at making nice wedding images for my clients .

To address littlejon, the mentality that something is better than nothing, is terrible. If you continue to do that sort of business practice, you'll end up developing the reputation that you're willing to work for next to nothing, or free. Nobody wants that, especially with your equipment, overhead, insurance, taxes, and the like being part of your costs of running your business.

It's all fine and good if you're just looking to get published. But if you want to make a living at it (and admittedly, it's getting harder to do so), you have to be firm on prices for your professional level images. Also, one more thing - when was the last time you remembered who took the photo of a particularly amazing image you saw in a magazine and called that photographer for work? I doubt it happens in textbooks.
