If you're looking to transport your cast to an entirely new set, there's no substitute for a
green screen studio. And the best place to find one is by inquiring into a film production location. There are dozens in the Atlanta metro area, concentrated downtown and peppered throughout the region.
When you book space with one, you get many amenities like light boards, sound equipment, camera rentals, and lighting modifiers. Not to mention the space itself. For large sets or major productions look into warehouse and loft production locations. These are usually outside of the urban core since space is less expensive. Many of these film production locations are former warehouses converted into multi use spaces. Besides movies, they are also used as photography studios, event centers, and even office flex space!
For a major film production you can even have staff on hand to assist with post production, camera operation, or lighting. Kitchens, break rooms, and bathrooms are also important since people will be on-site all day during a film production!
