    There is no fixed answer to your question.

    One may like to have warmer colour cast in the landscape to convery the mood of risiing sun or setting sun.

    One may like to have as accurate as possible white balance for a human portrait as too yellowish colour tone (or warmer tone) makes a person look like one suffering from jaundice. One may also avoid too bluish colour tone (or cooler tone) as it makes human like a pale as an anemic patient.

    The best option is to make your judgment of the white balance to best represent the situation. A good reference material of acceptable white balance setting would be to look at those with good skin colour tone photographs posted at Portrait and Poses sub-foum and Ready, Light, Action! sub-forum.

    "Correct WB" have 2 meanings, IMHO.

    1. Correct as in the pictures appear exactly the way the view is seen on site

    I guess there is no way to "make it correct" unless you're doing the post processing at the scene and adjust according to judgment by referring to the surrounding. If you have already left the scene, then it is quite impossible to tell what is the "correct" WB as you see it at the scene, other then by trying to recall.

    2. Correct as in "accurate", i.e. white object appears white regardless of the lighting

    In this case, it maybe possible to correct WB by PP if there is a white reference but the "correct WB" may not be pleasing at all. For e.g., there is a white object at the scene, and you know it's white, but if during PP you set it as the "white point" (which is correct), the picture may looks terrible.. It may not be exactly like it was seen, esp if the lighting is not white. Because even if the software tries to correct the WB, some colour might already been missing from the picture data that is needed to reproduce what the subject actually looks like under white light.


    Inspite of the above comments, if you want some reference for WB correction, you might want to visit the link. Even if the WB is not "correct", it might give acceptable results.

    For digital darkroom process, one may use these options as starting point

    - colour temperature of dominant light source lighting up the human skin
    - white balance point selection of white colour or neutral gray of picture taken
    - white balance point selection of picture taken with white card or grey card in picture

    Again, I re-emphasize my earlier statement "A good reference material of acceptable white balance setting would be to look at those with good skin colour tone photographs posted at Portrait and Poses sub-foum and Ready, Light, Action! sub-forum. "

    Alternative, visit Canon website and read PDF files of guides and instruction by Canon. Look at the skin colour of models posing for shots as posted in these PDF files.
