This is something I have been thinking of trying for awhile,(need to try it with a black back ground) but just did not take the time to do it, Kayla has to do a photo project for school so we are going to work on this.
Here is the set up total darkness, tripod, timer was set for a two second exposure,
lens aperture set at F/8, ISO 100.
5600 flash set in test mode for three short burst and hand held just left of the camera.
Not much to it but it does give some neat effects, will be trying more sone.
