Today I gave an Intro to Painting and the Pen Tool to color some pencil line drawings using Photoshop. You might find it helpful, especially regarding the Pen. I show how to paint the same object both in Paint and with the Pen, locking a layer’s transparency, the multiply blend mode, etc. Here is the recording of our Photoshop for Children’s Book Illustrators webinar hosted by Mark Mitchell.
