Consent and compensation, I think are the key issues. Anything that's going commercial, you need to get everything straightened out as others have already mentioned here.

Keep yourself available and reachable for the future claims if there are. Don't grant or share the rights of your photographs that you current hold to other people like book publishers if things are not clear.

That was my concern, too when I self-published a tiny book in Japan, and I selected non-human photos for that matter just to be safe because I wasn't too sure about the law over here, which is years behind the west.

So, don't rush to decide for your prestige work!
