Re: 3 color separation repair help -- blotchiness

Hey Klev,

As I described in my initial post, the image actually was created with 3 "decorrelated" black and white negatives, so a lot of work actually had to be done on each channel's negative before they were combined to produce a color image. Basically to achieve a remotely decent starting place, each black and white negative (channel) had to be pretty well balanced before they were put together.

The image has come a long way and is getting better, I have used corrections recommended by scoobey and wolfman, and am now perhaps dealing with overcorrecting using those methods because the image is becoming a bit too flat.

I read about frequency splitting but haven't actually done that before so have to figure it out...

Before & progress/after to demonstrate what I've been working with attached!

Color is looking pretty good. Now the smoothness of left leg and arm are a bit distracting, so give the tone some variety in those areas using DNB, just to make them less even. It's a really interesting image BTW.

That's pretty nice work. I've never used frequency separation for anything.

I should probably clarify what I meant earlier. RGB is a set of color spaces. Its channels correspond to different wavelength ranges, but they overlap. Working channel by channel in RGB will frustrate you because of this. It's simply not designed for that. I kind of get it if one channel is completely lacking detail somewhere. Otherwise save yourself a headache and productivity loss.

It's also possible that I don't understand your workflow. I get the impression that you're scanning these things as black and white images. If the color is so bad that you have to basically recolor them from scratch, I would still avoid doing any real retouching until you recombine them for the reasons I mentioned.

Also out of curiosity why did you make them so high in contrast? These are from a different era, and that contrast is quite high relative to the media that would have been available at the time.
