Topic: Do you use Onion-skinning?
I recently visited another stop-motion forum (not LEGO, though), and some of the people there are really good at animation, but apparently, a lot of the 'pros' don't use onion-skinning; instead they go back and forth between frames. Some of the people have been animating since the 80's and earlier.
Personally, I find onion-skinning very helpful. Do you use onion-skinning?
