I’ve been calibrating the ISF modes using 75% saturation, 75% luminance with excellent results. When calibrating at 100% saturation the color tracking reddens flesh tones like the VT30s. Does CalMAN auto-cal allow 75% saturation?
The VT50 10p gamma control works exceptionally well.
Edit: I use the ChromaPure Color Module 75% Rec.709 option for calibrating and ControlCal for making the adjustments.
