I made duplicates in Lab and CMYK mode and inspected all the channels.
The Lightness channel in the Lab mode was in perfect condition, as was the Green RGB channel. The rest were all contaminated with those ghastly blotches.
I took the Lab version and copied the Lightness channel to a greyscale PSD file.
Then I filled the Lab Lightness channel with grey and worked on the composite , which now contained only the faulty color information. I could therefore change the color information separately from the luminosity data.
I hit upon this notion, which comes from a tutorial by Deke Mclelland. A little known feature of Gaussian blur is this. If you blur a selection only the selected pixels are changed, but at the edge of a selection the blur takes account of pixels outside the selection. So, if a white selection on a black background is blurred, the black bleeds into the selection.
I selected the blotches with color range and expanded the selection by 1 pixel. Surely enough they were only a few pixels wide. When I ran Gaussian blur, as I moved the radius slider to the right the blotches were filled with neighbouring good color. I had to do this several times on very restricted selections but it worked.
I added the Lightness data back, converted to RGB, added the Greyscale PSD as a Layer in luminosity mode and worked on the color data in the background layer.
There were still some blotches that I stamped, cloned and patched away. I removed the color cast with Match Color, ran Auto Color and was presented with a workable file. I continued with a Curves Adjustment on a channel by channel basis and used Selective Color on the Skin Tones.
The hardest part was weird mauve skin discolorations, which I eventually removed to a large degree using Color Range and Hue/Saturation and Selective Color.
Lots of little details not worth mentioning.
I didn't try to remove the canvas texture because I like it.

Incidentally, I think the blown highlights in the hair are part of the original, but I was too tired to attack that as well.

Working with just the color info gave you a really good result! I'll have to check into your method for getting rid of the blotches! Cool idea!

Thank you. Franny. Just wondering, but do people like you do this professionally, or just for fun?
I took early retirement to devote myself to this and just wonder.
Photographs are such precious memories.

Wow, Tom you gave such detailed steps. Great job here. I like the way you handled the blue blouse (bottom left). It is so difficult to retain the colour to such precision. If there is a rating on scale of 10, a big perfect 10 to you.

Tom, not sure what you mean by "people like you," but I assume that is directed towards me! LOL! I'm strictly a hobbyist...fairly new to the game but loving it all the same. I'm been getting more involved the past few weeks since I found this great site. I would love to do this on a professional basis someday, but right now it is strictly for fun. Early retirement sounds good though, for whatever reason!
