So, what can I say. I'm a dog with a bone. Teach me a new trick and I chew at it to the nub. Sometimes I don't have the time to color in my work on site. It is easy to add color later, but some of those pieces look good in pen and ink as well as in color. So I don't want to add it. Using the program to add the color to them after I scan them to my computer. That means I can keep the original as is and have a color version too.
It is a mix of treating it like a water color and as a photo development. As you can see, the results are very bold. I really love how it retains the loose feel of a sketch and a magazine illustration.
