Skin tone color correction

Im trying to adjust the skin tone color for this picture. First all, I adjust levels (blacks, white and middle tones) . Then Im trying to adjust the color skin tone, but I dont know if the result is the correct. Anyone know one rule or method to adjust skin tone?
Thanks folks!

Usual cautions apply - monitor calibration, personal preference, etc.

Blood is red. The skin is just over the blood vessels. Ergo skin has lots of red.

The most common error I see in skintone color is lack of red. This results in what is called cadaver skin, the person looks half dead, blood drained away.

Levels can take you only so far. When you get the levels correct and a good black and clean white, look at the midtones. They are off here. The tool I use most frequently is Selective Color. In this case I don't want to touch the blacks or whites as they are fine. Click on the neutrals (won't effect blacks or whites) option fron the drop down at the top of the dialog. Adjust the red slider till the skin starts to pop, then maybe back off a little as one has a tendency to overcompensate. Turn the Preview on/off to check your color. Move to the green and see if any adjusments there help. Then yellow.

Your picture lacks quite a bit of red and notice that it also has a slight green cast. I added -8 to red (more red) and + 1 or 2 to green (more magenta). A little magenta seems to go a long way while red needs bigger doses. I have the options at the bottom set to Absolute in case you try my numbers.

Oh, and do this on an adjustment layer so you can take a break and come back latter ane recheck the color and see if you still like it. Our eyes tire and sometime in such a condition what seems to be good color is not. With the adjustment layer it is easy to change our mind.

Just a couple of thoughts. You have a sampler on the window. The sampler should be on the brightest grey part of the picture that is meaningful. I would take that to be the curtain near the bow. Also, I "think" the walls and trim are a white, if so, perhaps a midtone grey can be found on the trim. Your dark point could be raised a bit..see thru lingerie should be see thru.
On skin tone, I personally think you have too much Cyan and maybe just a little too much yellow. I usually try to find a light area of skin devoid of cosmetics. My preference is a very slight higher amount of yellow and cyan values of about 1/4 to 1/3 (assuming caucasian). Skin tones, I can only do in CMYK..not a clue in RGB. Hope this helps.

Duv, be careful when picking a white sampler. What you percieve as white often has a cast to it. For example, the window curtain is probably an "off" white, slightly warm. This will throw the rest of the balance off if you make it truely white.

However, your suggestion is a good one for a starting point. Do what you did and then take a look at the skin tones. Correct from there for the skin tones. People will accept a slightly off color background, but not bad skin tones. Your version still seems to lack enough red.

I have found that using Selective color, first on the whites, then neutrals, then blacks to work well. Often after you do the whites followed by the neutrals, some of the lighter grays get a cast to them. If you go back and readjust the whites, you can get rid of the cast with no noticeable effect on the neutrals. Don't know why this works, but it often does and I like it.

Hi Larry

When comparing our images, I might in fact prefer yours. The oddity is that your image has more yellow than mine, therefore "less" magenta. Secondly, windows..curtains. The point is, why would the windows be 242, 242, 242? The curtains may be white, cream..as the poster, you might have a better idea but from our stand point it's guesswork. Do you blow out that which isn't important such as the windows? Just a thought.

Mmm..also, maybe a high key would work.

Cheers
Dave
