Thanx, but this was done in Painter and is completely digital. I blocked colour in roughly first, then refined the edges of the colour, shaded it, added/refined the face, then the hair and finally, added some dodgy looking pencilly lines to it. I don't think it's a perfect process, that's why I'm trying different ways of creating art digitally. I haven't scanned lineart since this [link] .
I hope that makes sense. It's not always easy to see other peoples methods from the final piece of work. It might be nice to do an animation or movie which shows a piece being done.
Providing you leave your lineart as the background/canvas, you probably would change the contrast. I prefer to separate it and turn it into a color fill/adjustment layer. Select all your lineart, copy, enter Quick Mask mode, paste, then exit Quick Mask. You'll have your lineart as a selection (it may not look like much) which you can then use to create a color fill (Will need inverting).
