Are there any actual use-cases for this algorithm, specifically in darktable?
Did you bother opening the webpage (relaunch.piccureplus.com) the OP gave
and looking at their example section?
Do you think we don't have landscape, wildlife, insect, etc., etc.
photographers using DT?
Or just ordinary people who have that odd holiday shot with great
composition, light and everyone smiling but being oh-so-slightly out of focus?
I'd imagine 95+% of blurred images/images with motion blur
where that is not intentional, would be deleted and not processed..
And where did that number 95%+ come from? Some bodily on orifice? I refrain
from making an educated guess here from which -- to avoid foul language. ;)
Just because you can't imagine it, Roman, doesn't mean it doesn't exist. :)
To give you an example, to the contrary, based on actual numbers:
If you do low/available light (no flash) photography of people that move
(wedding photography, social dance photography, parties, events etc.) you
will usually have a ton of images that could be great if they only could
have a bit of blur (motion and/or focus) removed. Because even with fast
glass and high ISOs you will need exposure times that are too slow for the
motion depicted.
In my case, I photograph tango and swing dance events.
I shoot with a f/0.95 lens on an A7II body. There are no lenses of this
speed that have autofocus. And even if they were, the focussing would be
too slow. By the time the camera had hunted the focus down, the moment were
gone.
So I need to track focus and motion (of dancers) manually, at the same
time. Usually 10% of the images have either sharp focus or no motion blur
(both absent are less than 1%!).
Aka: at /least/ nine out of ten of these images would benefit from this
sort of deconvolution magic.
