Chad B gave me some tips in calibrating the ST60. He mentioned a window size of 5-6% with 18 to 25% APL is ideal.
Adjust 2 pt White Balance, using 100% for the high end but do not use 30% at the low end or you will end up with reddish shadow detail. Either leave the low end alone or do it at 10%. Don't do strong adjustment at the low end.
After setting brightness, contrast, and 2 point at 100/10 or just 100, start the 10 point by taking a 10 step GS/gamma run (out of the menu) and putting in corrections at the end pass by pass. Don't try to do the 10 point in real time. Just be patient and after each run, analyze the results and put RGB and gamma detail corrections in until you have things looking pretty good. (dE2K <1, good gamma tracking).There will be a lot of hopping in and out of the menu. Regarding the 10 point white balance, if you're going to have an excess of a color, blue is the least harmful to have an excess of. Green is the most harmful and red is in between. So if you are debating whether to have too little blue or too much blue at a given interval, go with too much.
CMS use 75%a/75%s and then run 25% saturation sweeps at 75%a for final tuning.
Go back to grayscale/gamma. Change to a 19 or 20 point run in 5% increments. Take a full run and do like before, inputting corrections after each run, this time paying attention to the in between increments (15, 85%, etc). Get your overall dE and gamma tracking as good as you can.
Take a full 20 step run without the menu up. After the measurements end, get into the menu. Starting with interval 1, look at 5, 10, and 15%, interval 2 15, 20, and 25%, interval 3 25, 30, and 35% and so on, your looking for the average of the three points to see if RGB is balanced at 100% if it's not then you know that you have to adjust starting with the 10% or interval one to better balance RGB between the three points. Then repeat the process, take another 20pt grayscale run.Get your overall dE and gamma tracking as good as you can.
Don't do the adjustments while taking continuous measurements.
