1) What property of the color are you changing with the RGB individual adjustments? Is it saturation (I'm assuming the Saturation control adjusts the three colors uniformly)?
2) Are the RGB offset and gain functions analagous to brightness and contrast functions, except for the individual colors? So, the offset adjusts the baseline dark end of the color and the gain determines the high end?
3) In the Color Management menu, is "Level" the same as saturation and "Phase" the same as hue?
Sorry if those are dumb questions - I'm still trying to digest the vocabulary and concepts surrounding color. If it's not possible to easily answer those questions, if someone could direct me to a resource that would explain these well, I would be very appreciative.
Thanks to all the people who share their thoughts here - this site is a very valuable resource, though there is an enormous volume of data to sift through.
Firstly - how are you sourcing your Z4?
My D65 settings are based around a specific set up, there is a chance that if one element differes then adjusting the brightness or contrast to suit will shift the greyscale range and white will become too yellow or too red near the top end.
1) The RGB individual adjustmenst effect the color of White not saturation.
2) Offset = brightness of individual RGB approx 40% IRE based chart
Gain= contrast of individual RGB approx 70% IRE based chart
There is interaction between the two.
I am struggling to explain the colour management settings accurately as Sanyos documentation is very poor.
But I read Level as the intensity of the colour, phase I would imagine is HUE.
With colour management you may have to find several scenes to make adjustments that you are happy with.
Bear in mind that I've only needed to make colour management adjustments to LIVING - not CREATIVE CiNEMA.
Hope this helps.
