Is it possible to select photos which have no lens correction?
What about making a list of the lenses used (you can't have that
many) with:
exiftool -T -r -lens 'directory' | sort -u > exiftooloutput.txt
Works in Linux, but I'm not sure if the "sort -u" would also work on
mac but then there should be something equivalent.
Then checking the "odd ones" with
http://lensfun.sourceforge.net/lenslist/
it depends on
- does Al want to filter the pictures with lenses not supported
- or filter pictures with lens correction not supplied
In the latter case I think it's more difficult => perhaps some
digging in dt database could result in a list, or you could try to
search for xmp Files without
darktable:operation="lens"
entry.
I mean the latter case. My filename includes the lens, so it would be
easy to filter, but that is not what I want.
Imagine you have a filmroll with 200 photos and complex image
manipulation. Every photo takes 5 seconds until it is loaded. So it is
very time consuming to check the lens correction by clicking on every
photo.
A similar situation is noise reduction. A selection with camera and ISO
would be interesting.
This can be done already:
My wish would be 3 technical criteria for a selection in combination
with a dt action.
That would mean having a selection for every dt module and it's settings
in the lighttable collection module?
Maybe analyzing the xmp-file could be a workaround. It looks like, if
there is no lens correction, the word lens cannot be found in the
xmp-file.
It's the string I mentioned earlier:
darktable:operation="lens"
But it is getting complicated, if there are lenses, where no
lenscorrection exists. I didn't find the lensmodel in the xmp-file.
