Here is a side by side version of my watercolour, using Someonesane's Video: Painting Around Imported Images with ArtRage Studio Pro Video, Ref:http://www.youtube.com/watch?v=mVbOjLhP5-M
I never have been able to master this properly, but I am now very pleased with my first attempt at this method. The first is the real life watercolour, and the one on the right with more detail and the background is the digitally enhanced version using Someonesane's method.
