Highlight clipping warning - random

Permanently deleted user
Continuing my tour of C1/20..

Have reworked an image - all fine.
Went to the next one, was surprised to not see any clipping warning where I suspected one.

Just to test, I blew the exposure to the max - actually, to the point that almost nothing was visible on the pict anymore.
No clipping warning ...
I assume tis is not the intended way, or is it ?

    No such issue with my version of C1 20. Highlight clipping works perfectly. Did you check the values of the clippings in the preferences ?

    Yes, I did. And this happens randomly, as the next image in the row was displaying clipping as it should.

    So why one and no the other ? 😭

    We talking about similar image types, like both are raw files?

    Yes, both from the same Nikon cam, taken at some minutes interval..

    Okay, thanks. Unusual behavior.

    Yeah, looking deeper into it.

    Problem confirmed with another pict, but still no "guaranteed" reproducible steps.
    Seems to come from the Luma curve - or somewhere there.

    At least, decreasing a bit the right-top corner of the Luma curve triggered the clipping warning in action again.
    Will try further and report the findings.

    Best "guess" for the moment is that "something" in the Luma curve anesthesiates the warning, and moving the curve again brings it back.
    Who said "weird" ?

    When I move the endpoint of the RGB curve downwards to say input 255 output 195, I never get a clipping warning because I have set this to 252, even when I move the exposure slider to +4.00.

    That is by design, obviously. Maybe this helps.

    txs for the info.
    It certainly helps chasing down the issue that certain picts do, others don't, while they are similar by time and place.
