P: Add color target profiling to Camera RAW panel

Please add a color profiling step to the Camera RAW processing panel. This would consist of a step wherein a reference image with a color target (Calibrite, SpyderColor, etc) is selected, and the color swatches designated by the user or automatic detection. The corrected color profile could then be easily applied to the complete set of images being processed.

For example: I work in product photography, and we struggle to get colors to stay consistent between cameras, lenses, strobe, and room variation. Currently there is an intensely manual process to color-match images of the same product shot on different sets. The ability to correct these variations with a common color checker target would be extremely helpful.

In the video world, these features are becoming commonplace in the color grading process: matching two cameras is becoming as simple as shooting them both at the same target, and making an automated correction, after which the colorist can edit from a common starting point. See: https://www.premiumbeat.com/blog/davinci-resolve-tip-using-a-color-chart-to-match-your-shots/

Currently, it is extremely difficult and time-consuming to use the third-party apps to generate a calibration sidecar file, import it, and keep track of these files. Integrating the color target calibration process as a single step in Camera RAW would allow large batches of images to be processed quickly to a more color-accurate starting point for retouching, and would be enormously helpful for anyone matching colors from different locations or multiple cameras.

First of all, the Spyder product is a massive kludge, this isn't a true MacBeth Color Checker; they have to provide this functionality and have to create a DNG/DCP profile and they don't. 

WITH a true MacBeth capture, this functionality exists with the FREE plug-in from X-rite which of course produces a real target and a true DNG profile from this. What DataColor is doing is a mess, a kludge and it isn't even producing a camera profile. 

True DNG/DCP profiles built this way, from multiple companies using a standard target all work the same way with this correct target and by creating a DNG/DCP profile. Only DataColor has subverted this path by making their own proprietary target, then updating other areas of the LR/ACR processing path. It's a mess. BTW, what DataColor states here is completely wrong: https://spyder-support.datacolor.com/hc/en-us/articles/4406395593234-What-is-the-difference-between-a-SpyderCheckr-Camera-Calibration-and-a-DNG-Camera-Profile-

 

"DNG profiles have the disadvantage of requiring a DNG conversion in advance, which may not reflect your usual RAW workflow, and DNG profiles are not easy to edit, if you have any editing tools for them at all".

DCP/DNG profiles work on proprietary raws or DNG. This is mostly snake oil and FUD, pass! 

 

Just get a MacBeth ColorChecker (or Passport) target. Everything you want to do is possible, including creating the profiles directly in LR using the free X-rite plug-in which will also be seen in ACR. And you can pick it as a preset, use it as an initial option on opening/working with the raws by the camera model, etc.

Then see what an actual DCP profile, that again, at least half a dozen other companies fully support expect DataColor bring to the party:
