A major advantage of shooting Raw is the ease with which the WB setting can be adjusted post shoot -even if carefully chosen it does not always produce the desired end result . I find this especially true for skin tones and much prefer being able to adjust and optimize the colour on my computer than rely entirely on the camera settings. I felt the portrait below would benefit from some adjustment to enhance the colour tones of the skin. The skin tones look rather too pink and I wanted to adjust these to enhance the subject. For this image I used a custom WB adjustment , not too severe but just enough to improve the skin colour.

The landscape image below was shot early evening and I used a Daylight WB setting which has created a rather blue cast over the entire image -including the grey concrete area.
