Here is another for discussion;
You are a stock photographer, you approach someone, lets say his name is Robert.
You ask Robert whould he be interested to pose for you for stock photos, and he will be compensated some money for his time, and both of you agreed $100 for a three hours shoot.
So the shoot is now and every turns out well, Robert sign the model release, received the money.
and you work on the photos, done all the necessary things, photos are uploaded to agency and finally available for download.
after some time the photos have some downloads, and some even appear on banner or advertisement. you earn loyalty from the downloads.
Robert saw his face on advertisement, at first he was happy, but after seeing more and more of his face here and there, he starts to feel resentment, Robert think you made use of him, and he should be compensated more.
So he contact you to ask for more compensation. and ask you to remove all the photos from your agency.
Questions:
Does he entitle to ask for more compensation after the shoot?
Does he have the rights to ask you remove the photos?
