I feel like theyre not accurate (but they should be, as with any technical data reference). For example, I was looking at the Kodachrome 25 data sheet, and the spectral sensitivity curve for the magenta forming layer seems too low. It seems like with sensitivity that weak for the green layer, any neutral grey objects shot under the correct lighting would appear pinkish due to access magenta dye. Can anyone comment on this? are the sheets accurate? Is my suspicion correct?
