Adobe Camera Raw woke up with no standard Camera Profiles.

 Yesterday, ACR and Photoshop were behaving weird. This morning the Camera Profiles were empty with only colour and monochrome as choices. I asked Google Gemini, not a worthwhile reply. Then tried Microsoft Co-Pilot, slightly better, but didn't solve the issue.

Looked at 

• C:\ProgramData\Adobe\CameraRaw\CameraProfiles\
• C:\Users\<yourusername>\AppData\Roaming\Adobe\CameraRaw\CameraProfiles

Both empty folders.

and that worked

Photoshop was 25.9.1, reverted to an earlier version, no improvement.

I shut down Photoshop, went to 

    C:\Program Files\Adobe\Adobe Lightroom CC\Resources\CameraProfiles

then I copied the whole folder to

C:\ProgramData\Adobe\CameraRaw\CameraProfiles\

and re-launched Photoshop and Adobe Camera Raw and that worked.

Don't confuse yourself by testing on an edited psd, test by opening a fresh raw file.

You don't have to accept that the default raw looks yucky

 Too often, people exclaim that when they display their raw image on the computer, the image looks yucky compared to the SOOC JPEG displayed on the back of their camera. You can customise that for all new images instead of re-working each image individually.

Here's how Adobe describes it:

The Misconception about SOOC Raw

Recently I saw a question posed about which camera (or camera brand) had the better colour. I explained that each camera will likely have a different colour profile and it should not be viewed as a technical superiority, the merit is most often subjective and affected by artistic interpretations. In short, it's a matter of taste.

There is also a misconception that if one takes a raw file from the camera and displays it the preferred editing program of choice, without touching any adjustment sliders, that it is SOOC (Straight Out Of Camera) raw. This is not correct. In order for the editing program to create a display on screen for you to asses, it has to demosaic, apply colour profiles, tonal curves, sharpening, noise reduction and even lens corrections. It's a bit like the old Australian ad phrase - "Clayton's - its the drink you have when you are not having a drink". Every editing program has to apply "factory defaults" as determined by the program maker (as opposed to the camera maker). In most programs, you can replace the factory default with your preferred "look", either on a one by one image, or in batch with a Develop Preset or save that "look" to the default.  In the last case, that means whenever you bring in a raw file, this camera calibration will be applied.

As Lightroom is one of the most popular raw editing programs, here are some screenshots of where you go to set up your personalised import defaults.

And here is a video by Mark Wallace about how to use the Xrite Color Checker Passport with Lightroom to set reference profiles and switch and also to offset the neutral colour to a wamer or cooler white balance:
