I am fairly new to Darktable and this is my first post in this forum. I don't seem to find any previous discussion that addresses my particular interest -- automating some of Darktable's processes to apply them to an entire series of images at a time. The History Stack technique doesn't seem to work for what I need.
Part of my photography activity is to convert old negatives and slides into high quality computer files -- RAW and JPG, and so far I've done about 24,000 conversions and a typical run is somewhere between 500 and 2500 slides.
My software of choice up to recently has been GIMP automated with BIMP which does much of what I want -- I can automate basic corrections on an entire folder of images in one process. The downside to GIMP is that it will not process RAW, which means I must accept my camera's processed JPG files as a starting point and that is far from ideal.
Darktable is great because I can start out with RAW files and do an Orientation on them right away but after that, things are not as I would like. A quick-and-dirty correction that works well is to use the Color Balance's Optimize Luma and Neutralize Colors buttons to brighten and color correct each image, and I can do that one image at a time but that's tedious.
My first desire is to find a way to automate that process -- to do the Optimize Luma and Neutralize Colors for each image in a folder in one step.
After that, as of now, I have to export to TIF (to keep detail but make the image readable by GIMP) and then use GIMP's BIMP plugin to do a levels stretch and finally export as a JPG.
I would like to ask if there is some capability in Darktable that I am overlooking --a capability built into Darktable that will allow me to run the Color Balance automation against an entire folder full of images automatically.
Ditto, I need a levels stretch capability in Darktable that I could run in conjunciton with the Color Balance steps that would allow me to make all the above corrections and eventually export directly from Darktable to JPG with the corrections all done.
Worst case I can switch to GIMP for the Levels Stretch but would still like to automate the Darktable Color Correction process.
