How do i blend a picture into a background? It's like this. I make a picture of an anime char and the background is all gray or white, but when i put it onto the background, the gray or white part of the pictures shows up and blocks the background a little? How do i Overlay the background onto the picture gray background? For example: Picture 1 is what happens, but I want to learn how to do it like Picture 2. Thanks!
