BTW, I spent a couple of hours last night working again with the new Adobe profiles. With the Adobe Standard Beta the facial tones are more natural though still not as good as the Nikon, not by a long stretch. They've calmed down the saturation on the reds significantly. What I really don't like is the amount of red tone they've added, I need about a -10 or more more on tone than I've had to in the past. No idea why they did that. But when I do get the WB right the facial tones have more depth to them, more natural.
Still want my 5D's to look like the Nikon D700, I was on the point of switching but my business can't afford it right now and there were some niggles which put me off anyway.
