I installed a setup, and I shot three photos with the same f/1.7 1/100s ISO100 condition:
How to use the Xrite Colorchecker (in photos A or B) to get calibrated colors, so that photo C will have proper colors?
Tools: Photoshop + Camera Raw + "ColorChecker Camera Calibration software v 2" (from Xrite), or any other freeware, but not Lightroom
Note: I've read many blog posts, tutorials, but it does not look so simple to do, thus this question ; please note that I don't want to make a "profile" for future use with this camera, but only to modify the colors for this specific picture / these specific lighting conditions.
Answer
Here is a useful tutorial, and a documentation in PDF: White Balance and Colour Calibration Workflow in Photoshop with the X -Rite ColorChecker Passport (Adobe Camera Raw 10.3 and Later).
The workflow is:
- Shoot in RAW or DNG an image with the Colorchecker visible with good lighting
- If needed, convert the RAW to DNG (either using Lightroom > Export > Filetype > DNG or using DNG converter
- Use Xrite's "Colorchecker Camera Calibration" software in DNG mode to open the photo
- Save the exported profile as
.dcp
file inC:\Users\User\AppData\Roaming\Adobe\CameraRaw\CameraProfiles
Open the image in CameraRaw and choose the profile in the
Profile Browser
:Working!
Failing methods I've tried (when using JPG or TIFF files):
Use Xrite's "Colorchecker Camera Calibration" software in TIFF mode (from a JPG converted to TIFF). The output is an
.icm
file, and I haven't found how to use this.icm
in Photoshop or CameraRawConvert a JPG to DNG with DNG Converter: not working
Convert a JPG to DNG with Lightroom > Export: working, but:
this DNG cannot be read in Xrite's "Colorchecker Camera Calibration"
this DNG can be opened by Adobe's
DNG_Profile_Editor_win_1_0_4.exe
, and the latter can detect the Colorchecker and output a.dcp
or.dcpr
. But unfortunately, even when copying this.dcp
inC:\Users\User\AppData\Roaming\Adobe\CameraRaw\CameraProfiles
, this profile doesn't appear in theProfile Browser
when opening CameraRaw with a JPG/TIFF
Conclusion: it doesn't work at all with JPG/TIFF (or JPG/TIFF converted to DNG), but it works with true RAW/DNG files.
Other methods I've tried (when using DNG files as input):
- Use Adobe's
DNG_Profile_Editor_win_1_0_4.exe
: the output .dcp profile gives another color rendering than the one I obtain with Xrite's "Colorchecker Camera Calibration", when using it in CameraRaw.
