The next series of light paintings I'm planning will use a slide projector to cast a complex pattern. I have a large collection of slides, many taped together to layer images on top of each other. Some I used bleach to almost destroy the color. Some I scratched and etched away parts of the image. Still have to figure some things out, but can't manage using the projector right now, with the foot-cast still on, as it involves a lot of moving around and maneuvering.
So while you, my impatient viewers, drum your fingers in anticipation, I'll post some older light paintings from the Guanajuato series.
