Re: Exposure value handling weirdness

Sorry if I am getting in late into the debate - I'm catching up after
one month on the go.

actually the case is not so rare. I sometimes load a stitched
equirectangular (first image, no EXIF) and the second image is a
normal rectilinear shot, straight out of RAW conversion, with EXIF
data.

agree if it is possible not to go back to the old and tedious process
of having to input HFOV for each and every image loaded that does not
have EXIF.

would it be possible to:
- first load all the picture and read whatever data is available
without asking anything to the user
- if there is missing information, present the user with a table where
each image is a row (ideally with a thumbnail in the first column) and
each piece of information is a column, so that the user can
conveniently link / copy them or enter individual values.

sounds like the "Reset..." button would be split to many buttons
across each of the columns of the table?

the table would have one column for exposure which would give the
indication, and an option for the user to reset it?
