Not the cameras. The Orthochromatic film used in the process.

Regular or Panchromatic film, btw, sees cyan just fine. Be sure to get the right film for your setup needs ;)

In my defense, it’s been 40 years since I did any of that cold type stuff. When I visited the offices of my college newspaper five years after graduation the manual typewriters had been replaced by Macs, and paste-up was a thing of the past. PageMaker had replaced it.
