I'm new to Green Screen, I've only used this program 5 times so far. It's so easy! I wanted to get more in depth in toy photography, I tried using a monitor as a background but then you get reflections - so I thought I'd give green screen a try and after a little looking around I settled on Savage Green as I only needed a program for photos and didn't see the point on spend a lot for a video program. I was pleasantly surprised how simple this made it, even getting rid of the dark green shadows and green reflections on my figures. It works fine on my Windows 10 machine and I see nothing that hints this isn't a full version as others have said. It is so SO easy to use :D
