One of the nice things you can do with light painting is to control the contrast. Only a little light in the shadows - dark shadows. A little more light, shadows aren't as dark. When I light-paint small set-ups I vary the dwell time on the different parts by intuition and then check the results. For light painting, chimping is your friend.
Karen, When you are in the dark, literally and actually, a little light goes a long way.. I have been wondering if you could paint in small area's, over multiple frames and blend together.. Thanks for the help.. Jim
