Thanks for the comments..
No long exposure with light painting.. it is smoke photography (no brushes, no filters,..)
The editing I did to it: levels (to increase contrast a bit and make black black) and some cloning/painting away excess smoke that wasn't adding to the picture..
For more images and info, have a look at my site & blog Lumendipity photography (bottom). There is also a link to a good article on photocritic
