What would be the best way the fix the color in this (108K) image example:

<http://www.saunalahti.fi/~shmhav/original.jpg>

The original 2048×1536 image was taken indoors with outdoor color balance so there is a very strong red color cast in the foreground.

The Levels’ gray eyedropper produced some ugly posterization on the face. I got slightly better result with the following technique (from Eismann: Restoration and retouching):

I sampled color from the shadow of the white collar, created an empty Layer and filled it with that color and inverted it. Then I set the Layer’s Opacity to 50% with Color blending Mode. I brightened up the foreground with a Levels adjustment Layer and masked out the brightest spots in the background. Then I lowered the Fill Layer’s Opacity to 45% to make the image a bit warmer. The result is at:

Are there better techniques for this?

I tried using curves and got a better color for the furniture and face, but the shadows pixilated pretty bad, maybe because it’s a low res web image. Check out

I have also posted a curves adjustment layer you can copy onto your original to see if it helps or not.

Matti…

Have seen what you’ve tried to do as well as what JP has attempted…. Think you’re both on the right track but are going a bit overboard.

Basically, it was shot by tungsten light… and tungsten light has a warm tone… all you need to do is lighten/reduce the cast on the woman’s face and arms and a couple of other judicious places such as her shirt maybe… leave the back ground alone and let the cast remain there. It gives a nice warm feel to the pic which is missing from both your attempts. After you get her skintones right, use a layer mask and just include those areas.

Just my 2 cents…

Cheers,

JJ

Go to the Channels Palette and look at the Blue and Green Channels, try using both upper and lower sliders in Levels to flatten the contrast in them!

Image->Adjust->Selective Color and Image->Adjust->Curves do a pretty good job of getting that red cast out.

The posterization is actually exaggerated noise, because the blue and green channels contain little other than noise in the face. You can get a much smoother result by using the channel mixer to mix 50% or 60% of the red channel into both the green and blue channels.

Using the Kodak Digital ROC program, the auto adjustment was mag/green +5, ylw/blue -15. This produced a better picture, but the woman’s skin tones were still way to hot. Using iCorrect Pro, setting auto white/black point and selecting "flesh tones" (selected in the darker areas of the neck) provided a better result, but there is considerable graininess in the skin areas. I’m sure that masking the woman and doing some playing around with the channels (blending and blurring) could improve things further.
