1. Enable Green Screen
Social Booth has built in green screen removal. If you shoot your photos on a green background, you will be able to let users select their own backgrounds that replace the green.
2. Enable GS Overlays
Green Screen Overlays are transparent png files that are placed on top of the photo after the green screen effect has been applied, creating a bit of depth in the shot. The included examples are just a brick wall that gets placed on top of the final photo. But you can use different overlays for each background. The overlays are defined by having "-overlay" at the end of the file name. For example, the overlay for background_01.jpg is background_01-overlay.png. Be sure to follow this naming convention if using green screen overlays.
3. GS Background Folder
The default green screen folder is C:\Program Files (x86)\Photo Booth Solutions\Social Booth\Assets\GreenScreen but you can define your own folder with your own backgrounds. You can have up to 6 backgrounds. You can have less than 6. If you only have 1, the user won't choose the background, and every photo will automatically use the same background.
4. Minimum/Maximum Tolerance
These are a few parameters to tweak if you are having problems getting a good green screen image. With proper lighting, the default settings should be fine in most cases. Min tolerance = .1 and Max tolerance = .3
