I should add that I plan on choosing one frame from each roll and printing them to match the gray card as close as possible in my darkroom using Kodak Supra Endura (the optical stuff), then comparing that to a drum scan corrected in PS for the gray card and printed on Supra Endura VC (the digital stuff) with a Lightjet. That will satisfy my testing criteria to demonstrate any shift in color and density at varying temperatures and output methods.
