ProMaster Backdrop Bungee
The ProMaster Backdrop Bungee will help you get better images when using a studio backdrop. When you have a solid color backdrop, the wrinkles tend to create shadow areas. This is particularly an issue when working with green screen.
Use a pair of these handy back drop bungees on the uprights of your background stand. Clip the sides of your backdrop to the bungee, snug it up and you will have a virtually wrinkle free background. The Background Bungee can also come in handy when you need to hang a backdrop and do not have room to set up a background support.
Keep several of these handy ProMaster Backdrop Bungees in your studio tool kit.
