Hi All:
I am doing some Zone System Testing, and due to lack of a densitometer, I asked my local camera store if they could read my developed negs for density. They were kind enough to do so, but the values they gave me were in RGB.
They are as follows:
Film Base + Fog = R6G7B7
Zone V = R119G119B119
Zone 0 (-5) = R16G16B16
Zone I (-4) = R28G28B28
Zone II (-3) = R46G46B46
Zone III (-2) = R72G72B72
Is there any way to convert these numbers into regular film density values?
Thanks,
Rich
