Have you downloaded the reference Lab file together with the image (CCvari.zip)?
Have you founded the right RGB Prophoto values with the same software (GMB ProfileMaker 5)?
Have you replaced the standard RGB values within the script?
Have you tweaked the adjust tab in ACR before opening the image in PS?
Have you setted the script like author?
Have you compared the final results with the right Lab file (My-mini-CC-LabD50.txt)? The Rags reader works fine in this way
In this article you can read the details of the author technic if you know Italian language or you can see the screenshots to found the right RGB target values with the freeware ColorLab together with the suggested script setup.
Hi, and thanks for answering. I had not read your article so close and did not notice your changes to scripts and so on.
I changed one of the script with yours values and saw better results.
I am doing this for hobby mostly and is interested in camera calibration just for fun. I have a mini-colorchecker which I thought had correct colors. Therefore I could not see the need for calibrating the colorchecker also.
If that is the case the hole calibration system is not as easy as just taking an image of the colorchecker and run the scripts. Then the need for calibrating the calibrater will come up and so on.
But I will stick to standard values for my colorchecker and just shoot images with my 20D and run the scripts. I guess the colors will improve then too!
Some people has noted this and for this reason I have wrote the second article explaining the details of all passes.
The Colorchecker has not to be calibrated but read with a spectrophotometer. This is an optional but if you want precision I recommend this pass.
Conceptually, with some advices, the process is easy but the results and the research of precision sometimes carry frustration and waste of time even though using not commonly hardware and software.
