Which calibration settings did you choose ?

I choose full calibration and setting like this tutorial video.

Okay, I watched the video.

two things stood out:

1) He sets his display for 100% brightness. Unless you have either terrible eyesight, work in a high glare situation, or have a very weak display (in which you should get a new one), that is a terrible idea. For two reasons

- it is much brighter than what you want for a photographic purposes. General web standards are 120cd/m(2) or if printing, something in the 80-100 cd/m(2) range.

-if the display is set for full brightness, the only adjustment Range for individual color brightness is lower.

2) at the 9:10 mark he shows how the gamut of the profile he has created is substantially smaller than sRGB. We have 2x MacBook Airs (one is a 2018 model, the other a 2020 model but pre M1), a mid 2015 15” Retina MacBook Pro, and a mid 2014 27” 5K Retina iMac in house. All of them according to i1 Profiler software and BasICColor 6 profiling software have profiles gamuts slightly larger than sRGB.
Now sRGB is the smallest common color working space. It is the most commonly used one because it is small and therefore most easily reproduced. However because it has the smallest gamut, there are lots of colors found in nature and that your camera can record which exist outside of it. What happens to those colors? They are pushed down into the limit of the color space or profile (a display or printer’s profile is a color space specific to that device). This colloquially known as “clipping”

As we see at the 9:10 mark, his “calibrated” profile which is based on the calibration parameters he set, is even smaller than sRGB. That’s not good. But yes it makes the colors look punchier and contrastive.

why is your new profile yellowish in appearance? I don’t know. Which standards did you use for calibration? D65 or D50? Etc.?

But there is another possible factor as well. I do not know if they ever fixed the problem, but Datacolor’s colorimeters (a colorimeter is the sensor or “puck” used to measure the screen) in the past did not have a great reputation for color accuracy. It is possible that you have a bad one. Sorry.

I was using D65.

Do you ever use DisplayCal ?

Today I try use DisplayCal by following below tutorial. Result bit better.
