We Just finished hosting a class in CibaChrome printing, taught by Nancy Ori, at Peters Valley. Great class.... On the last day I brought in a popcorn drum to see how the CibaChrome Paper would work as a pinhole target. I'm happy to report that it works just fine, with an apparent EI of 6. As one would expect from a paper balanced for Tungsten light, the image looks much nicer with an 85B filter in front (or in my case in back) of the pinhole. The 32 minute exposure showed no discernable shift in color. The slight corrections that I would make probably correlate to the lot filter correction.
