I switched over to the color disk and am soooo lost. Can someone give me the CMS color guide for noobs?
what's up with the .025cd/m2 MLL? guessing you do not have black optimizer turned on? that's at least double what it should be at. and unfortunately, that's making your target gamma pretty different. if you've not going to use BO, then no worries. but i'd turn it on, get the lower black level, and touch up the gamma(it likely won't have the second curve at 90% anymore).
as for CMS, here's what i found to work:
-turn on the cms(select custom)
-run your grayscale/gamma and make sure they are accurate
-select rec709/75% under references
-run the primaries/secondaries measure using the 75% saturation slides from the saturations folder, and the 100% white slide from the colors folder
-now go into your CMS, and look at each color on HCFR one at a time. while doing this, look at the numbers, not the pretty CIE chart. the graph on the bottom left will tell you what values need to be adjusted. SEE NOTE BELOW!!
-so after you've done each color at 75%, and the dE's are low(should be able to get under 1.0 no problem), go back into references and select the normal rec709(your dE's will now likely be in the teens, don't worry, that'll get fixed in the next step)
-re-run the primaries/secondaries measure, use the patterns found in the colors folder(the dE's will still likely be higher than before, but hopefully under 3.0)
-run the saturation sweeps. i like to do one color at a time first
-after you run the sweep for each color, have a look at the dE's, focus on the values 25-75%. adjust the cms controls to see if you can improve the dE's slightly. you shouldn't have to make large changes at this point, likely only 1-2ticks before things will start getting worse instead of better. SEE NOTE #2
-after going through all colors, run the primaries/secondaries measure, and full saturation sweeps one more time to confirm nothing has changed.
-if dE's are mostly under 1.0 in the 25-75% range, and under 3.0 at 0% or 100%, that's about as good as anybody has gotten so far, so relax, and enjoy.
pay attention to the delta luminance values(you may do this after if you want, but doing it while measuring 75% values might save you some time). if the delta luminance is extremely high(+) when your x,y lines up well(the dot is inside the box on the CIE chart), then you want to increase the color setting in your basic controls. obviously after increasing color, you will have to adjust the values in the cms(reduce them) to bring the 'dot' back inside the 'box'. but now, the delta luminace should be lower than it was. don't worry about getting it right at 0 right now, cause the other saturation points will be different unfortunately. i only suggest looking at this now because with color at 50, i had delta luminace values of like +30! bring it down to single digit values, and your dE's should be easier to keep under 2.0. oh, and if that wasn't enough, the menu will affect the readings. so as you're adjusting the RGB values, make sure you close the menu, and run another quick measure before moving on. you obviously want the lowest dE's with the menu off, as that's how you'll be watching content
if in doubt, somewhere between 53-55 seems like a safe place to start. the higher the setting, the less vivid and cartoony the color will be AFTER adjusting the CMS.
again, i would take a quick look at the delta luminance numbers. if ALL of them are very plus, you may need to increase color, and redo the cms adjustments. each color will be a little different, so don't run red saturations, and if they are all +5, panic and raise color, cause chances are when you get around to green, it's going to be -5 after that. better at this point to run all the colors(at least primaries) before deciding if color should be adjust further. i've found that a slightly + delta luminance is less bothering than a slightly - delta luminace. so i would keep color at a setting that prevents any one primary from going too negative
