Batch-convert (aka batch-process) camera native (RAW) files into whatever image format you wish! Darktable supports most camera files from Sony, Canon, Nikon, Fujifilm, Olympus, you name it! Full list of supported cameras and their formats here:
Convert to EXR (OpenEXR), JPEG, TIFF, WebP, whatever.
Truly incredible tool if you take 30 minutes to get familiar with it.
Here’s a video for beginners on how to develop a RAW file from start to finish using Darktable:

7:09 Yes I am.
I was just thinking about how to take company specific RAW files and save them to some common format such as DNG or open-exr! Thanks for sharing this!
I'm curious to know your Blender based editing workflow also. Looking forward to it!
In one of your replies to me, you mention "Even though we select linear rec709 as output, the data outside that gamut is not clipped, but fitted", would you be so kind to point me to the documentation on this.
I began to read the Darktable manual and must say that, at first glance, when it comes to colors, DT is very advanced, probably alone in its class and beyond what can be done via an ICC base workflow alone. So yes, it's very likely I'll become a DT user pretty soon.
Thanks for your patience with me,
Yves
Thanks you
Thanks for the excellent video. You mention, you did this to keep as much as possible the original data from your raw (captured data) files, right? I wonder then about the use of Rec709, though I would agree that for the images you have selected, it doesn't matter much. For most of mine, it would mean a potentially tremendous lost of color through clipping. I've made an ICC profile for my camera and it as a gamut a bit larger than ProPhoto. Using ColorThink Pro I can see some color I can capture with my camera are obviously clipped by ProPhoto. Like you, I'd like to keep everything I can from my captured data in an open format, EXR would be one of them of course. Or at minimum, I'd like to do an image dependent gamut mapping, without clipping of course. This would be done to fit nicely in a colorspace large enough to cover current and (near) future display spaces and also print media. Currently, I use papers, inks and a printer that provide me with a gamut of about the same volume as Adobe RGB but of a different shape, so it protrudes from Adobe in some areas and the inverse is also true. For the moment, I always use at minimum linear gamma ProPhoto RGB, 16 bits tiff files using dcraw_emu. But to be able to do an image dependent gamut mapping, I almost have to reinvent the wheel as most colorspace profiles are matrix profiles, which implies only colorimetric rendering intent are possible.
Would you recommend the same file format and color space for moving the images into affinity photo? I've been using TIFF but get really large files sometimes. Also if I export the photo using sRGB would that then limit the amount of amount of colors to work with
Thank you so much for the presets!
What's the caveat for not clipping negative gamut for the EXRs but choosing to clip/roll-off them later?
