Negative scanning issue

[Barry Watzman]

I'm scanning a bunch of 30+ year old negatives (35mm). Most of them are
the typical "orange" look, but some of them have a heavy purple look
rather than orange, and I'm have a very difficult (essentially
impossible) time getting good color reproduction from these. I presume
that they were not well processed (just a guess on my part). Anyone
have any information or guidance on what color adjustments would
typically "fix" such negatives?

I can't help you with fixing the color, but check the film type along the edge. If all the purple ones
are the same type, and none of the orange ones, it's the film, not the processing. And, IIRC,
the orange color is a dye in the base, and not processed in, so it wouldn't be bad processing.

Try scanning some frames as slides and post the URL.

(I just about always scan as slide because I don't like what NikonScan does
in it's 'negative' mode).

Hi.

Way back in olden times, there was a published method for removing the
Coloured Base Dyes from Neg Film without damaging the Image.

It might be worth while researching that if it is the Film Colour rather
than Faulty processing.
