Freytag uses only Larson Enterprises brand lighting equipment in this video. I’m not entirely sure, but I think it might have been produced as a promotional video for the lighting equipment sold by Larson Enterprises. At the very least, they co-sponsored it. However, they managed to avoid the hard sell or “you can’t do this with any other product” mentality that you would typically find in such productions.
The techniques demonstrated here are centered around manipulating natural light by using reflectors and diffusion. No electronic flash is used at any point. Despite the fact that Playboy has a reputation for elaborate lighting setups, most of the setups here in the video are relatively modest and could be easily duplicated by a photographer and perhaps one assistant.
Sadly, the video doesn’t seem to have ever made its way onto the DVD format, and is apparently no longer produced on VHS either. Used copies are selling at collector’s prices, so if you happen to run across a new copy collecting dust on the back shelf at your local camera shop, you should check it out, even if you just end up watching it once before selling it on eBay.
