Kodak says that the Gray card for 5242 & 2242 should be R1,10 G1,45 B1,55 which is true for 5242 but not for 2242.
If I measure the base of 2242 inter negative I get R0,08 G0,60 B0,66, the difference is the base material which is, in case of 2242, estar.
So between the two types there is a huge difference in base density of R+0,06 G-0,15 B+0,27. In blue the difference is huge.
How came, and in the Kodak technical papers are having the same LAD values?
I haven?t been able to get this numbers from 2242.
I compare the measurments of LAD from both 5242 & 2242 and I found that If I subtract the base densities from both measurements, I?m getting exactly the same values of 0,7 in all colors (RGB).
I?m having a feeling that 2242 needs a special pre filter to be added in the positive printer (to print in 2383) in order to fix the blue, in contrast of 5242 that doesn't need it. I also think that there is an error in Kodak documentation that says, both films are having the same LAD values in status M.
Any suggestions? John, Dominic ???
