Hi there,
I am new to darktable and I have a series of pictures that show a lot of hot pixels, all in the same locations.
The images are .jpg, so I cannot apply the hot pixels module to remove them, since it only works on RAW images.
Hence, my first question is:
is there an automated way in DT to remove hot pixels on non-RAW images?
I thought, I had an ok solution: I removed the worst dots in one image using the retouch module.
I then created a style including the retouch and applied it to another image of my series.
However, the retouch - although appearing in the new image’s history - was not applied and hence did not remove the hot pixels.
That leads to my second question, in case the first brings no solution:
(How) Can I apply my manual retouch spot healing from one image to another? Manually removing all hot pixels in >400 images is no option.
In case it matters: I am running DT 3.8.1 on Ubuntu 22.04
How about some kind of low-pass filter/blur, with drawn masks covering just the bad pixels? The idea would be to blend them with the surroundings.
3.8.1 is quite dated, but I assume you are aware of that.
Thanks for the reply!
The question is, if that would be applicable as style to new images. My approach with retouch worked well until I was unable to convey it to other images. So I wondered, whether I am missing something obvious there.
It would have suited my work flow so I thought I’ll see, if there is an easy fix in dt that I, as newbie, am just not aware of.
But if there is no easy way, GIMP is probably a good alternative, thanks!
I haven’t worked with GIMP much as well. Do you have a specific tool in mind and know, that it would work for my use case?
