I have learn that a great starting point for a white skin tone should be:
M and Y are the same, with a little higher percentage of yellow. C is 1/5 to 1/3 the amount of the Y and M numbers. K = 0.
For example: C=8, M=30, Y=32, K=0
My questions is how to use this starting point in Aperture. Hope anyone can help me with this.
