Does the whitebalance skintone adjustment works for non-caucasian when I use the dropper? If I understood this feature correctly, but using the dropper I am telling Aperture where the skin is and how does Aperture know what the original's person skin color is? Does it automatically assumes everyone is caucasian first?
I could not find any documentation, that states that the white balance is restricted to certain types of skin colour. I experimented with a varity photos with people from different countries, and compared the results I got for using skin tones to the ones I got for using same gray in the same picture, and the results were similar. If the skin tone correction was not satisfactory, because if bad lighting conditions, the corrections with gray tones was equally bad.
You might wish to experiment as well, for example: upper left: original, upper right - skin tones of the face corrections, lower middle: natural gray (taken from the shirt):
But I guess my question is I'm not understanding the logic of the feature. For neutral grey, it makes sense because you're telling Aperture which part of the photo should be absolute netural grey and it then fixes the whitebalance based on that reference.
But what does skin tone mean? You're telling Aperture that the dropper is pointing at some skin but Aperture might not necessarily know what that skin should look like. It doesn't have a reference point like neutral grey does. The skin could be anything. So does it guess?
It does well with a variety of skin types. It's not caucasian only. Have you tried it? I've had great results the vast majority of times I've used it.

But it does - the tan of human skin is caused by a well-known pigment - melanin - only the amount of melanin varies; so the hue of skin can be predicted, only the saturation will vary.
Me too. 🙂 .
Note that the algorithm also takes into account whether or not a face is detected in the Image. (See your local Help file -- this information is not, afaict, in the on-line manual yet.)

No, the trusted online manual is slowly turning into a historical document 😝
