I found some info on refracted lighting that I am going to read - and try to comprehend today. If I find anything significant I will share it.
Jiminy - Snow shots ..... hmmm .... I'd probably be shooting with my macro lens, which means that their would be a significant focus issues because the distance of the camera (inside) and where the snow is located (outside), would be pretty large!

All kidding aside, not yet, but I have the perfect environemnt.
