What camera are you using?
Are you shooting raw files or JPG? (Camera calibration applies only to raw files.)
You only get camera matching profiles for raw files from Nikon and Canon cameras and a few others. For non-raw files (jpegs, tiffs, etc.) you'll only see "embedded"
tks for your answer.
am using samsung NX500 shooting in Raw files only.
just discovered that the new version of LR6 has automatically applied the said camera "standard setting" to all imported file so my previous action did not work.
to check whether it applied correctly, press "alt" in PC in edit mode, the right bottom corner button originally read "reset" changed to read "set default", then press "set default", it came out my NX500 name. of course can change to others if we don't like.
the button wordings may not be correct since mine is chinese, just translated to english by my own.
