I haven’t done light painting for a while.  I really enjoy doing it, but it is very tricky and takes along time.  Good for cold weather.  I set everything up with lights on, turn focus to manual, set aperture to F20 and shutter to 15 seconds.  Got a pen light and made a snoot out of paper for the end.  Turn lights off and hit shutter release and paint away with the light.  this is the result.
