Hi,
I think that even negative film can be problematic. I did a test with Ektar 100 and got obscene colors. The reason is probably that blue channels is exceeding the DR of my scanner. The enclosed figure stops at D=3.0 but I think the channel goes much higher.
Hi Erik,
That Blue channel D-max is not an issue, provided that your scanner adjusts the exposure time of each channel properly/individually to neutralize the mask. It's the difference between the D-max and D-min for each channel that should be handled by the scanner's dynamic range capabilities.
Without proper mask elimination by tuned exposure times, all bets for good color are off.
Cheers,
Bart
