Here's a sketchbook study I did of Lucia....
Lucia With Green Background (Watercolor and gouache in Moleskine sketchbook, 5x8").
I bought a Sony Cyber-shot camera a few months ago. It's small, convenient, and takes great pictures. When I pointed the camera at my drawing, it identified the face and framed it. There's a certain validation that occurs when the camera interprets a portrait I drew as an actual person's head. It's technical confirmation that I'm getting something right.
After I took the picture, the screen displayed a funny, yet impressive message. The camera alerted me that the person had blinked. Smart camera.
