Re: Difference between ACR Calibration and Colorchecker Passport

I have Adobe made and X-Rite Passport made profiles for both of my camera.

They two types of profile are very similar (as they should be) but there are some significant differences. Not just in color either -- I see subtle differences in shadow and highlight detail too.

Generally speaking I prefer the X-Rite version.

Obviously, the best results will require correct color management settings on your software and a decent calibrated monitor.

However, the manner in which you shoot the color test target is absolutely critical. I took the time to:

* Place the target on a mid-grey background. I used the eye-dropper readings from that to confirm that illumination was perfectly even.

* Confirm the chart is parallel to the plane of the sensor.

* Shoot multiple exposures and select the best based on the RGB readings on the white patch.
