Guys, i am creating packing for my product. And i need quality photo of baby using it. It's something specific, so i can't find it on photo stock sites... I decided to call local baby photographers so they can find the baby for product shots. Do i have to sign any kind of agreement? Between me(my company) and the parents of the baby? It's like i am hiring their baby for modeling, and i need their approval for the photo to be used on my products. Any advice how to do this in best way? Never dealt with this before, any advice/info would be very beneficial! Thx!
