Hi, developers,
I have always missed seeing exposure bias value in darktable. Does
anyone else think it would be good to have that shown in 'image
information' on the left? Perhaps there is also a nifty way of
indicating exp. bias somehow in histogram?
By mimicking source code for exposure, I was able to get exp. bias from
exif and then output among other metadata in 'image information':
https://gist.github.com/sarunasb/f5eb4644dbf3e07174069c46f668e89b
Of course this only lasts until images are loaded for the second time,
as there is no exp. bias in database, if I'm correct.
At the moment I'm not too familiar with darktable's code for database
operations. It looks like common/database.c has schema upgrades, but
then there are multiple instances in the code, where schema has to known
in order to be used explicitly for inserts, for example.
I have the code for displaying exposure bias in a fork on Github
(https://github.com/sarunasb/darktable) and can make a pull request, if
there is any interest for it.
If this is seen as a feature worth adding, would someone familiar with
database ops be willing to pick up? I can try looking at it myself too,
but at the moment I don't even know what I don't know, so to say...
