Unfortunately, I lost my darktable database (and my hole disk) and had to rebuild it from the XMP files (from backup), which took several hours. Now I’ve run into a strange issue: all photos (around 4,000) taken with my iPhone 15 Pro Max and converted from Photo RAW Max to Adobe DNG using Adobe Converter appear green in darktable.
What’s odd is that this never happened before when using the old database with the previous installation of darktable.
Has anyone experienced something similar? Could this be related to a global setting in darktable? Any advice would be greatly appreciated!
You can make the change in one picture, the CTRL-Shift-C copy only the white balance and color calibration, select all your pictures, and Ctrl-V paste that setting to all your pictures.
But note that each of your phone’s cameras may have a different default. Theoretically, resetting to default should select the appropriate default for each, but if it doesn’t, group by camera (front, back, wide, tele…).
Thank you for the hint. I would like to find out why this happened only after building the db.
Furthermore what is suspect is that I already had that color calibration in my change list (which might be the default automatic applied changes from the past).
I thought this might be the reason for the wrong color. Therefore I tried to delete the color calibration in order to get rid of a wrong color in order to avoid the need to add another color calibration the second time but I was not able to delete the step by clicking at the icon right to the text.
Both color calibration and white balance are necessary. They can not be disabled. But they can be reset to their defaults, which should fix whatever went wrong with your database.
I suspect they somehow ended up with the wrong coefficients.
Then the question, if something is wrong in this db, whether it would make sense to start again by creating the DB from xmp files in order to avoid problems in the db ?
I assume “resetting the edits” means clicking on “original”. If I do this, I see the picture without the extra green color. It is just the original photo.
Not true: both can be disabled (through the modules panel on the right, not through the history stack). When I do that on my raw images, those do turn green. So at least one of them is necessary.
And we used to have only the white balance module…
In my experience, dark and greenish pictures with a history stack can be rescued by reseting the raw black/white point module.
The settings used by this module seem to depend on ISO and usinmg the same setting for an ISO 100 and for an ISO 1000 raw causes the ISO 1000 raw to look the way your DNG looks.
You most likely have an autopreset. I’m not in front of my PC at the moment, so I dont recall the actual default preset. Look in the hamburger menu for the preset.
