I just bought a used digital color densitometer (a Cosar 75/76) to use for zone system testing. How do I use it for assessing black & white negative densities? There are settings to measure densities for red, green, blue, and red-green-blue combined. No setting for B & W. In addition there are separate settings for E6 and C41 processes, each of which covers the same color choices. What do I use? C an anyone advise?
And the same question applies to assessing B & W reflection densities.
Thanks
