So I'm trying to make an image that fades out at the border like I did in a sig a while ago. I remember learning it in a youtube tutorial where the guy used a penguin for an example and the fade took place based on how many times you hit the 'delete' button for something you did to an oval placed around the object. This sig I did it in was this one (specifically I faded out Megan Fox's body).
If anyone can find me this tutorial or remind me how to do this, that would be awesome.
