I use the add layer mask tool to isolate the main character of an image and modify the background. It's a pretty simple tool and hopefully you can take this simple idea and do some great things with it.
In this tutorial, I teach you how to create the very popular effect called 'Sparkle Trails.' Sparkle Trails are a kind of surreal type of effect that adds to every type of photo to create a cool-feeling.
