I am looking for a release form so I can use pictures I took of my clients on my website and on promotional material.
I have no intention of selling the photos.
I have no idea what to even google. Any suggestions?
Check these links, I have found them all useful in the past.
(If you have a Getty account then you can just download theirs. The same may well go for other stock agencies.)
Edit: also check out this iPhone app, it looks excellent and the releases generated are accepted by Getty and Alamy: https://www.facebook.com/pages/VMRelease/105679776169458
If you are in Canada, you might consider the CAPIC release form templates.
