Ok, thanks. Thanks for answering my questions so thoroughly I've done some vectoring by hand with Photoshop, for my own amusement really. It's quite addicting I'm looking forward to learning more with Inkscape.

Ah, ok. That leads me to my next question, is there a way to pull apart the colors and then re-align it back to the original photo, or do you have to nudge each color back into place by hand?

Is there a way to load the results of a bitmap trace into the layers palette, similar to PS? I know how to run the tracer, but want to be able to separate each color as a layer.
