post processing - How does one do light painting with in focus subject? Maybe a composite?


I understand and have tried some rudimentary light painting, but I'm still not sure how one might achieve something like the photos here: http://www.modelmayhem.com/portfolio/pic/18221422 Is this just a composite of different pictures in post production?



Answer



These photos seem to be shot with softened off-camera flash and long shutter time -




  • the light trails tell away the long exposure;

  • sharp model can be explained by having been lit very briefly during that exposure;

  • there is no "deer in headlights" look, so the flash (or flashes) must have been off-camera;

  • the shadows have soft boundaries, so there must have been some kind of softening used on flash (a softbox, umbrella, bounce etc).


I would advise against using the second-curtain flash suggested by AJ - flash in the end of exposure means model has more time to shift away from focus, and when you have moved the camera to create some of the painting effects, framing will be off too.
