Letz me splain...
On the photo you're referring too, yes it was shot indoors and the effect I was working on is easier outdoors. Basically what happens is that if you put a green gel on your flash, the light is now green. It hits your subject the strongest, and the light your subject reflects back through the lens is now green tinted.
When you use an exact opposite, not only in color, but in density, like a 30 green and a 30 magenta, the green light off your subject's skin is now cancelled by the magenta filter (gel in this case), but the green light doesn't reflect as strong off your background, thus your background now takes on a deeper magenta cast.
In the case of this image,
it's harder to see, but it saturates your background with magenta or a tint of magenta.
When you do this outdoors, the green light doesn't hit the clouds and come back, it dissapates, however the clouds and sky now have to pass through the magenta gel thus they get a tint or saturation of magenta in the final image...it's a technique I'll demonstrate this Oct. in NYC at Photo Plus Expo.

Well I'm off to bed, tomorrow I fly back to Texas as we wrapped up the latest workshop here in Chicago. A special thanks to Ralph Hasseltine for his support along with his son, the crew, models and attendees....
For the record, we'll be practicing this at the upcoming Virgin Island's workshop in November and the April 2006 workshop at the Virgin Island's next year during Carnival...here's an example of the effect outdoors, enjoy...thanks, rg sends!
(Both images shot with a Hensel Porty Premium and a Hensel Ring Flash. The ring flash has a Rosco Green Gel and the camera lens has a Rosco equivalent density magenta gel...)
