I used a photo taken by one of my students to paint this demo for a weekly painting class I'm teaching this month. It's a local metro park near the place where I am holding the class. I photograph every step then throw them into a Powerpoint presentation so they have a step by step map for their painting. Many of the people taking this class have never painted before so it's very helpful. They also have a print of the original photo so they can see what I modified to create the painting.
