Hey Holly,

Thanks for the tip! I ordered my diffusion grid sheets from EdmundOptics.com a couple of days ago and bingo, they had already arrived yesterday! A lot of packaging for a little sheet. The cost was $19.27 with shipping.

Anyway, I have had some interesting revelations as to the shortcomings of my studio lighting. I can't believe how fluorescent lights are composed of just a few simple steps on the spectrum scale. It is no wonder that so many colors can look so dead. The so-called full-spectrum incandescent bulbs seem to completely lack the production of anything in the yellow range (as do the fluorecents). My 500 watt photographic halogen lamp has a full spectrum 100 CRI, but it is 3200 K, rather than daylight. I wonder how the so-called 98 CRI full spectrum fluorescent tubes look?

Looking at a television or computer monitor, it is obvious there are only three phosphers, i.e.: RGB.

Thanks again, whenever I look at new lighting, I take one of these sheets along for a quick analysis.

Garth
