I recently bought a KRP-500m from a local seller in Los Angeles. I activated the ISF modes and am attempting to calibrate them. I bought an Eye One Pro spectrophotometer and I am using ColorHCFR software.
I got brightness, contrast and the grayscale to be pretty much perfect. Now, however, I am having trouble adjusting the color and CMS. Can any of you give me some advice on how to get the color points as close to perfect as they can be?
I have no idea how to use the CMS controls. I played around with them and I got some changes, but not really substantial improvements overall.
What kind of Delta E errors should I be shooting for? The colors that are off the most seem to be blue and magenta.
I am getting red with a delta E of 1.5, green with a delta E of 3.0 and blue with a delta E of 6.5 to 7.
As for the secondaries, I can get both yellow and cyan to have delta E's under 2 but magenta is WAY off, usually with a delta E of 9 or 10. There seems to be almost NOTHING I can do to get the delta E on magenta under 8.
I want to know how calibrators like D-Nice are able to get their color points so close? What type of results should I be able to expect on a KRP-500m?
Is it more important to have delta E errors that are roughly equal or is it more important that certain colors are accurate at the expense of others?
Can you clue me in on what results I can achieve and what the best method is to set the color points? I am sure there is some secret or quirk in these displays that I am missing to get the color closer.
Second, I am a bit confused on the gamma. I was trying for a higher gamma at night, like 2.4 instead of 2.2. I want to see how that would look. However, I don't really know how to adjust the gamma. As it is, I have a pretty flat 2.2 gamma but I wanted to change it to see if a slightly higher setting would be beneficial in a dark environment. But how do I do it?
It probably involves the "ISF gamma" controls, but I have no idea how to use them. Could you help me out here? I was under the impression that a KRP-500m could be calibrated to produce a flat gamma line pretty much anywhere from 2.2 to 2.5. I want to compare the different target gammas and see which looks best in different lighting conditions.
I would really appreciate if someone could help me here. Thanks.
