I'm not using Darktable myself, so I can't check it myself but this might be a re-occurrence of a bug that has been fixed two years ago. You might file a bug-report with them and while it's been discussed/fixed, you can revert back to the previous version to keep your stuff functional. Edit: Checking the documentation you might try to call darktable-cli ...

Unfortunately, you can't run multiple instances of darktable at a time. If your script is running 4 instances of darktable-cli in parallel, there's your error. You need to serialize your script to run at most one darktable-cli at a time. Having some kind of file locking mechanism that waits for the old darktable-cli to exit is needed. An example of such a ...

Just add a style preset with: exposure: auto white balance: camera (or spot - whole image) sharpen: defaults base curve: defaults With that my severely underexposed pictures will look nice out of the box. (I always use my native ISO 200, and will rather use Darktable to make them light than to do it destructively using ISO in-camera). This is basically ...

Here's a quick and dirty solution with exiftool and cmp: 1) Make copies of the two image files: cp img1.jpg tmp1.jpg cp img2.jpg tmp2.jpg 2) Use exiftool to remove metadata: exiftool -all= tmp1.jpg exiftool -all= tmp2.jpg 3) Use cmp to compare the temporary files: cmp tmp1.jpg tmp2.jpg cmp exits with a message if the two files are different; if they'...

There are different levels of "The same image" Some programs mentioned in the "Possible duplicate of How can I identify duplicate image files? analyze a fingerprint of an image. I understand that they analyze sort of a low-resolution version of the images and compare them. This is to compare a small matrix of data to reduce time. Some of them mark "...

Use green screen & some fast isolation software, such as those from FXHome - the older PhotoKey or the new Imerge (which I haven't tried yet, but seems to also be half the price of the old one.) Other solutions are available, but that's the one I've used the most. Googling for stills software isn't as easy as for movie, but it's out there somewhere. I ...

You do not need plugin for this purpose. Moreover current level of software/AI is not enough to "say" which image is good which is bad. The method I use is sample and quite strait. You select Survey mode: View->Survey or press N. Then Photo->Auto Advance to make LR switch to the next image when you rate current one. And use numbers from 1 to 5 to rate (usual ...

Middle-of-the-road solution with Gimp, that crops and straightens the images, assuming all your pictures are numbered in some directory (IMG_2027.JPG, IMG_2028.JPG, as long as there is an identifiable number suffix, you can even have missing numbers). install the ofn-file-next script, and use Edit>Keyboard shortcuts to assign it to a key. File>Open the ...

darktable-cli $src $xmp $export [options] --core --library ':memory:' --configdir '/dev/shm/$uniquevalue' It seems that there's also a data.db in the --configdir parameter (default: $HOME/.config/darktable) which also gets locked by a darktable session. This probably holds user preferences and styles, but if an xmp sidecar is specified then it's not ...

This is pretty easy to do if you can write in Python. Here's a good article on using an open-source computer vision package to detect overall picture blurriness: https://www.pyimagesearch.com/2015/09/07/blur-detection-with-opencv/ Here's a quick script that will sort pictures into blurred/ok directories: # # Sorts pictures in current directory into two ...
