I use a webcam logitech c920 and I get a lot of gray dots (about 45%) when I enable green screen setting with something green in background. I watched the tutorials and the problem is because the program is still experimental for the webcam? or because of the shade of green or poor light in the room?

    We do lots of green screen and we found that the c920 does not work with green screen the only one that works for us is the c922

    I shall give back this c920 and buy the c922 model, and see how it works. Thanks for the advice!

    I see your main problem is BAD LIGHTING...
    even if you use the c922, you will not correct that problem
    unless you learn how to Light for Green Screen.

    Search YouTube and you will find a lot of video
    on how to light for Green Screen.

    Because I read all the discutions that I'm intrested, if maybe someone needs help, I have solved the problem this way. The webcam logitech C922 is far better (I found the green flower in background between my child's toys), and also got a yellow light that changes the blue color of the box in green, as in picture attached. To work fine is needed a fluorescent green in background.
           Thank you for your advices, and quick responds!

    Yes the C922 is better but like Joe says lighting is very important if you don't have proper lighting its impossible to get the green screen result me and Joe have study this intensely and we discover that you need perfect lighting to achieve green screen. you can have the best camera in the world if your lights are off your quality will be off to. bellow am posting our photo booth take a look at the lighting and see the results.
