Firstly, we require every person to fill out a model release. We now have hundreds of model releases on file. It's getting a bit out of hand.
Instead, what we'd like to do is include verbiage in the initial session agreement/contract that by hiring us to photograph company members the company agrees to let the members know that by partaking in the shoot with us they are agreeing to release the rights of their likeness etcetera. If they object to this "bulk model release" then they can sign a form against our use of their likeness. This would effectively lessen the number of signed releases to save to only tracking signed objections.
Has anyone heard of this actually being applied? We can't be the first ones to ask, although we can't find anything like it on Google.
