Hey, So I've stumbled across something that I'm curious about. I picked up quite a few wratten filters and whilst reading about them in the booklet "Kodak Filters for Scientific and Technical Uses" came across this interesting prospect. Straight from the book.... "Printing with "Three-Color" Filters. Color print materials are sometimes printed with separate red-, green- and blue-light exposures rather than with filtered white light. The exposure through each filter is varied independently to control the color balance of the print. One such three-filter combination is KODAK WRATTEN Filters No. 25 (red), No. 99 (green), and No. 98 (blue). These filters, whose spectrophotometric curves are displayed below, are suitable for printing Kodak color negative products on Kodak color print materials (both film and paper)." Now, doesn't this seem enticing? It seems to me like this would give you the ability to control color balance more akin to dye-transfer or tri-color carbon. That is, having complete control over the exposure of each individual color. Or, does this really provide an advantage? Is anybody out there doing this? What do you think, intrigued enough to give it a shot? Look forward to your comments, Cheers!
