How is this lighting and colouring effect achieved?

Question

A few days ago, I saw this picture linked here on 500px and was wondering how the coloring technique is called.

On a first glance, it looks like a high key shot, but it is unusual as it has no light background. I'm wondering what kind of photoshopping was done here. Is it just removing saturation and adding a bit exposure? I hope this style has some official name so that I can look up the details on Google. But at the moment I'm struggling, because I don't know what to search for.

Answer

I agree it looks like a 'vintage' effect. The skin looks yellow/green. To test this, I brought that image into photoshope, added a curves layer and used the gray point dropper on a light part of her jacket, assuming it was neutral, and this resulted in more normal skin tone.

Then I used a color balance adjustment layer, and moved the Magenta/Green slider towards green (+22) and Yellow/Blue towards the blue (-22), and the result looks almost identical to the original.

I didn't change the saturation, but it looks like the image may have been somewhat desaturated, as you suggested.

This is a harsher green vintage effect here. Looks ghastly, but the technique uses separate channels in a curves layer which you might be able to tone down and make use of. And another one here. Or search on photoshop/gimp vintage effects.
