Taking a well deserved (!) break from Kodachromes I started playing
with B&W negatives today (Ilford, if anyone is curious). I wonder what
the panel thinks of the less "sensible" of the possible scanning
permutations for B&W negatives:
1. Mono Neg/Grayscale - boooriiing... ;o)
2. Mono Neg/RGB
3. Color Neg/Grayscale
4. Color Neg/RGB
5. Color Pos/Grayscale
6. Color Pos/RGB
For example, scanning B&W negatives as Mono Neg/RGB has obvious
advantages because some blemishes are much more easily corrected with
access to 3 individual RGB channels, converting to grayscale only as
the last step.
I wonder if there are any similar advantages to some of the other
permutations specifically in terms of, say, dynamic range or
sharpness, etc.
For example, at first blush, taking an individual channel from an RGB
scan seems sharper than a grayscale scan which, presumably, started
life as a composite (all 3 LEDs on).
Another example is that fine scratches appear easier to spot if
scanning as Positive and then inverting as the last step, etc.
