I've been doing this process of hand drawing my animation on paper and then doing my "ink and paint" in flash. But recently I've been seeing people take their cleaned up animation into photoshop and just color on top of the pencils. then they export the colored frames into after effects.
So my question is this: I already know how to color in photoshop. what I want to know is how are they making the background of their frames transparent? Are they just using the magic wand tool to select the white of the background and delete it? if so, how are they selecting it without getting those ugly artifacts?
