I only occasionally need to use a graphics tool. So I have SnagIt on hand as it does what I need.
But now I want to make a photo taken against a green screen transparent. SnagIt supposedly does this. But as I am not a lighting expert so my green is not 100% consistent. In that, it is various shades of green (within a range) depending on the flash.
What I need is a tool that lets me adjust the sensitivity of the transparent color to allow a range of greens.
Can anyone offer any suggestions, preferably for a free program?
