There are options to modify this behavior in Bridge. Preferances/camera raw
What are the differences:
automatically open JPEGS [TIFS] with settings
automatically open all supported JPEGS [TIFFs] with settings
disable JPEG [TIFF] support seems to mean one cannot open them in raw
By the way, I notice image settings are saved in Sidecar '.xmp' files. Is that preferable to Camera Raw database?
I probably used .xmp because I used to do everything in digital negatives. Without grandchildren around, I take few pictures and they are tiffs or jpegs.
I appreciate anything you can eliminate.
If you open jpeg in ACR and click done you have edited it even though you have changed nothing. It will then open in camera raw the next time.
You can cancel these settings on highlighted image with edit/develp settings/clear settings. It will then open as a jpeg.
If you open jpeg in ACR and click cancel it will open as a jpeg as no edit was made.
THe XMP is preferable to database as the latter is more susceptible to file contamination.
Hope this is helpful or the correct answer.
Exactly the information I need.
Many sincere thanks.
