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.
