I want create an animation, and for this I need to create some pictures. My example consist in a envelope opened. But I need to execute this steps:
Paper tearing(rip) effect - (This step it's easy and I know how to do).
Paper roll/curl effect.
Paper roll/curl effect a little more.
So, I need a help to do steps 3 and 4. I'm a begginer on photoshop, for my creations I usually search on internet for tutorials, but in this case I don't know what I need to search for.
