Sony A9G calibration result

Just want to share my calibration result using HCFR and my old 2012 i1display 3 colorimeter unit.  Have to spend alot of time to get the gamma curve right if I have to take gamma correction into account. The final outcome is not perfectly linear but the result is very pleasing to my naked eyes.  Save myself $140 USD for the Calman for Sony software though!

I started reading the Calman workflow http://sonyglobal.akamaized.net/ ... .CalMAN-updated.pdf to get an idea of the workflow. Only change is that I set the peak luminance to low instead of medium.

I used Ted's calibration disk (https://displaycalibrations.com/) as I don't have a blu-ray player and I also use his devicecontrol software to unlock 20 points grayscale control (more on this later).

final result:

average grayscale dE is. 0.91, max is 1.9
average CMS dE is 0.73, max is 1.25

I didn't save the before measurement though...

I hardly need to use the 20 points control as I can get 80% of the result using 2 points adjustment. Most of the time I spent is to get the low and high end gamma correct using the black and contrast control. I could have use more time to flatten the grayscale curve but it's hard to find time to do it :-)

C Hing, if you are viewing in a dark environment, you can try another calibration with gamma 2.4 - as this is the gamma usually used for mastering the current movies.  You will notice that the image will have much more depth and "pop" with gamma 2.4.

Thx Dom, it's easy to do with the Sony as you can adjust the gamma independently.  In theory Sony will scale it based on my setting done using 2.2. I didnt test and measure to verify the result though.
