During an extended power outage this weekend I had some help from my son and we attempted some light painting. It's really not that hard to do with a little setup and practice. I used my GX1 with a 25-30s exposure at f/7 on the manual setting, and manual focus on my 7-14, on a tripod. We used an LED flashlight to "paint" once the shutter opened. It takes a little practice to get the right flashlight size and the right amount of ambient light "spillover" from the flashlight. I hope to try it again with more effort put on the composition. Give it a try - it's a lot of fun. With this one he traced around me and shined the light directly into the lens to get the bright flashes. I stood as still as I could for the 25 seconds. With this one I wrote on an imaginary plane, turning the light on and off when I started and stopped each character. The light shining on the ceiling came from the flashlight shining upward. The fun part is that you have to write backwards. It definitely takes some thinking to get it right.
