I received an email by someone asking to use a photo I have posted on one of my websites for use in a book. It's not from my photography website, since obviously that is still under construction as I have been sidetracked by other projects. However, they do want to use one of my photos and emailed to ask permission to use it.
The woman who contacted me is "assisting" someone from a company that publishes books for academia & professional development.
They want to use my photo as a figure in one of the chapters of a third edition of a book. The manuscript has 1,250 pages, estimated print run of 500, and publication date of 10/30/2017. The second edition of the book can currently be bought on Amazon for a price of $80.80 with a list price of $125.95 (probably what students pay in the school book store).
They email made no mention of licensing or an offer to pay. So I am curious what you guys think the best approach is to reply, and how much money I should expect for the usage of my image in such a case? I assume I should be prepared for 2 different numbers, one for licensing the use of the image in the book, and the other for exclusive purchase of rights to the image. The second one would be a much higher number, as the photo is already in use in a blog post of mine. So I don't think that is what they have in mind. But since it is an official publication, they require licensing rights for any image they put into the book. If they want to use my image, they are going to pay me. Sure, yay, I'm flattered that you want to use my image in your book. But that good feeling I have is about as useful to me as it is to them. If they wish to use my image in a book they are selling, then they need to pay for it.
So, estimated print run of 500 copies in a 1,250 page manuscript, but the second edition of the book only has ~700 pages. One image in what I am certain are many images.
So, I assume I reply to the email with something along the lines of:
Obviously, if I am the first person to say I number, I am putting an upper limit on what I will be paid. If I make them say a number, they are putting a lower limit on what I will be paid. This is the first time I have been approached out of the blue by someone wanting to use one of my images in a book, so any advice on how to proceed is much appreciated.
Thanks!
