A fun thing to do as a photographer, especially when I am bored, is to test film I've never used before. In this case, the film is Kodak Vericolor Reproducing Slide Film 5072, which expired in July 1992. I inherited it about eleven years ago when the folks at the Randolph Air Force Base photo hobby shop were getting rid of old and expired film, and it has been in my freezer ever since.
This Vericolor stock was never meant to be run through a camera, but rather was manufactured as a lab film for making 1:1 slides in C-41 process from E-6 and Kodachrome originals.
Apparently, time has also rendered it totally devoid of yellow and green hues. The posts in the foreground are a blazing amber, but all that remains is the magenta.
But, for blue and red objects, this seems to be just the film I was looking for!
