An acquaintance of mine sells her hair accessories on Amazon, Etsy and her own personal website. She has asked to buy some artistic photos I took of my daughter wearing her hair accessories (as a model) for her various sites, to hopefully, help her sell more. She is also interested in future photos.
Most importantly: what would be a fair (reasonable) price to charge her per photo?
What other considerations do I need to think about. (Ex: I told her if I did sell her some photos, none of the face shots would be for sale to protect my daughter's privacy; just her hair and slight profile that highlight her products)
I don't particularly care to retain the rights of each photo once it is sold because it is so specific (who would want that particular photo in the future?) Should I reconsider this?
