Hosemaster light brush - Painting with light: Lighting Technique Forum: Digital Photography Review
Hosemaster...it was a very popular, high-end light painting machine that top commercial/fashion/product professionals used to use in the 1990's. The machines still turn up for sale on e-Bay occasionally, or through high-end resellers like Lens & Repro on
B&H,
Adorama, Calumet Photo,etc.
I used to do night-time light-painting outdoors, using Kodachrome 64 film, at f/8,sometimes at f/5.6, tripod-mounting my camera, and then "painting" urban landscapes with 10,15,20,30 "pops" from a Vivitar 285HV flash that I powered from a Quantum Turbo battery. It's possible to set the camera up and "paint" the front of a very large building with overlapping pops of flash, walking around the scene and aiming the flash at the various elements from different positions, so the lighting is even. Using slow speed film, like 64 ISO, allows plenty of time to leave the shutter open, and reduces the critical nature of each pop of flash.
There are some landscape shooters who use LED and/or regular flash lights + starlight and or moonlight to "paint" large landscape features using hours-long night time exposures. In commercial/product photography, there are times when I have heard of photographers using the flash units' modeling lamps to "burn in" and add some light by using a very slow or long shutter speed, or slowing the shutter down to "pick up ambient tungsten" from table lamps or other lamps in a photo, to give a warmer feeling and warmer color balance to a scene.
