I have been invited to shoot my very first Fashion shoot. It's a TF setup, so I won't be getting paid. The studio is giving us free time to do the shoot. The MUA is giving her time and the clothing store is supplying cloths and two models. The studio has an intern that's setting things up and has two models scheduled for the shoot. He wants two or three photographers total and he will be doing a behind the scenes video.
My question is this: I want everyone to have equal billing with the use of my images.
That's to say the Studio can use my images for their studio promotion as well as the MUA, clothing store and models. I want everyone contributing to have credit wherever the images are used.
Why type of contract would be used for this type of collaboration. I have model release contracts already. Thanks for any help you can offer 
????????????
