Just a thought- I often take photos at local dance events for the ladies in my troupe. The performances are public, so of course we don't have any control over people taking their own photos and posting them on the internet. That's a non-issue with us, although if the dancer is credited, it's certainly appreciated. IMO my photos aren't high quality, but I gladly offer the unrestricted use of the images by the dancers in them, if they wish.
However... a local business owner, not associated with these events, but who has had a business relationship
with some of the dancers from time to time, has appropriated photos of dancers on more than one occasion, and has used them for promotional purposes without credit or compensation, even going as far as to reproduce them on merchandise.
Unethical at the very least, and potentially illegal if it's not part of a contract. Most recently, it happened with some of my own photos that I posted for the dancers in my FB album. Thankfully, it didn't appear they were being merchandised, but still- not cool. Now I include this in the album description, "... unlimited non-exclusive rights belong to the dancers to use your own images, if you like. If you see a photo you don't care for, let me know and I'll delete it. Everyone else, be respectful; no reproduction without permission of the subject, please." That seems to have put the brakes on that issue, as far as I can tell, and with that business owner, at least. We'll see.
Anyhow, I got windy, but I say that to suggest including a comment on your album stating your own feelings about photo reproduction; maybe it'd help (?).
