To me, those two directories contain the 75% and 100% saturation patterns along with the appropriate 75% or 100% gray pattern to be used in each case.
Or am I way off.
They are different.
The ones in the 75% Color directory are 100% Saturation, 75% Stimulus.
The ones in the 100% Color directory are 100% Saturation, 100% Stimulus.
The ones in the Saturation directory are all 100% Stimulus, but are 100%, 75%, 50%, and 25% Saturation.
If you calibrate using the 75% or 100% Color patterns, you will get the same results either way, as long as you use only 75% or only 100% patterns since they all have the same Saturation levels. They will show up on the same 100% points on the color gamut chart because the color gamut chart shows Saturation and Hue levels, and all these patterns are 100% Saturation.
However, the Saturation patterns will show up at different points on the color gamut chart.
Here is an example of a color gamut where a display has been calibrated to 100% Color patterns but where the resultant lower Saturations are off. This shows an instance where calibrating using 75% Saturation patterns would be preferable.
Here is the link where these images came from. Although the thread there describes issues with Epson Projectors, the information there can be applied to any display. Many thanks to stereomandan for this detailed explanation.http://www.avsforum.com/avs-vb/showt...7#post16166537
