I just shot a MacBeth card, using the 5 different Styles built in by Canon into the 7DII and unaltered by me. I also shot it RAW, using Daylight WB under a partly cloudy but 4:45pm sky. I read the images into LR and left ALL paramenters totally unaltered.
Which style is which? And which shot is the RAW shot? I can see differences in rendition of the same patch across the six shots...look at the Red square as one obvious difference. The 'flesh' (top row, patch 2) is apparently differently between the six.
I am puzzled, in considering the prior comparison that was posted...maybe I need to enlist a woman of color to pose for a test series so I can do it again?!
For reference I did check the 4th tonal patch for neutrality, grey seem suitably equal in the three channels, with only shot 4 having a relatively higher difference in G channel (vs. R or B channels) but that seems understandable given that it is 'Landscape'. Looking at the value of R vs B, most had very similar values in the two channels, and only in shot 4 was B higher than R by 0.3 units...that was the 'Neutral' style.
I cannot jump to any conclusions based upon this test series...I wish I had a model of each skin group (northern European, Asian, Black, Latin, native American) in the same photo, with a grey card, and shot in the five factory Styles, to try to jump to some conclusion!
