The Zenitar yellow filter should be close enough to a Wratten #12 for it to not matter. > > Any possibilities of "invisible flash" type photography with this film, > as is possible with the HIR B&W? Hard to say. It is actually an extended red film, and doesn't have a heck of a lot of IR speed. Really wonky curves actually. If you are going to try, I would recommend getting an 850nm cut filter for the flash, as that is where the cyan layer sensitivity falls into the sewer. William Robb
