Their solution was to dust off an old Kodak Carousel slide projector. The original 35mm slides were projected on a screen in a darkened room, right beside an Apple Macintosh displaying the slide's scan in Photoshop.
"We had the image on the monitor with [Hemlock's] technician at the computer, and we had 3' x 2' slides projected," Rosemarie says. "Pat and I are sitting there with laser pointers, saying, 'Okay, that has to be glowing brightly against the aquamarine blue of the ice, you have to get that shade of blue, and this contrast needs to be fixed.' We pointed out what was critical about each image, and color-corrected the scans on the computer monitor. Then we produced six to 12 hard-copy Fuji Pictro proofs, one by one."
