Any good guides on here or at least a list of steps or techniquess to do and I can google for videos on the techniques. I have never used photoshop (gimp) in my case but I have an understanding of the steps... At least I think

1. Scan playfield
2. Magic wand certain colors/areas
3. Somehow get those onto a new layer and eye drop original colors
4. Finish new layer by drawing in any missing art and hide old scan.
5. Test print to change colors until they match
6. Make your water slides etc.
7. I assume you can make circles/lines/ arcs of specific dimension size in these programs too?

I know the mountain tips but need to understand the valleys and details.

Thanks!
