Hi, I’m aware that Apple ProRAW is “explicitly” not supported by darktable. There are also old post about this topic, but I’m wondering if there is a way to mass convert them to DNG/other format that can be edited in darktable. Any suggestion appreciated.
DNG is not an image format, it is a container file type. It is the internal image data that cannot be handled by darktable. Converting it to “DNG” would not help.
Just use Adobe DNG Converter.

I second Adobe DNG converter, which is free for any unsupported RAW file for use in any software that doesn’t support a specific camera.

I’ve used Adobe DNG Converter for a while now. It’s generally OK, but things get weird with far out things - like using the iPhone for infrared. I blame the crazy white balance settings in those cases.
I use the app “iMazing” for phone backups, and it exports ProRAW files as DNG’s. DT can’t read those (only the embedded jpg), but the Adobe converter makes it readable in DT.
RawTherapee seems to have figured out how to read the files. At least it presents an editable image…but can’t be saved other than as a jpg or TIFF for use in DT.
digiKam just gives up, and uses the jpg for editing. Maybe RT is doing the same thing, behind my back…
I’ll have to try one with ImageMagick…
PS - I have forgotten how to even get an Apple raw from my phone to my PC. I have read several how-tos, and nothing is working the way I want. I’ll have to get back to this when I have more time.
hey @Tim this weekend I’ve found that Halide can shoot in a DNG format compatible with darktable. Here a PlayRAW I took this weekend as an example.
Is that Raw or ProRaw? Remember, DNG is not an image format, it is a file container type.
Anyway, I have Halide, and I fooled around with all that stuff in depth a year or so ago. I concluded that it isn’t worth the trouble.
It’s RAW. More info here. It’s the output of what they call Process Zero (RAW). But you can check yourself downloading the file I shared.
Edit:
From their post:
To summarize: Process Zero gives you a single 12-megapixel shot. It will be less saturated, softer, grainier, and quite different than what you see from most phones. Each shot includes a true Bayer RAW file, if you want to use it in a full-fledged RAW editor, but we designed Halide so you don’t need one.
That is new to me. I haven’t paid much attention to Apple Raw or Halide, lately. I’ll check it out.
PS - Well, no wonder I’m just now hearing about it. It was released one week ago. Thanks for bringing it to my attention.
Hi Tim,
you can download RAWs after login on icloud.com (if you use icloud!?) easily.
just select Photos and folder of RAW images, then select the images with CTRL+click and click the three dots on one image to see other download options. There you can select to download the selected RAWs in a zip file.
After conversion with Adobe DNG converter they are ready to be used in darktable.
That workflow is acceptable for me.

I do have iCloud, but I use Linux only, so I don’t have DNG converter. I can make it work though. Thanks
I was able to make it work with wine. That‘s probably what you meant.
Btw avoid profiled denoise module when editing iPhone raw images! There was a thread on this somewhere in the past.
Kind regards!
No, I don’t use Windows at all. I just meant that if I can get the Apple raw image to my Linux PC, I can work with it.
So do I, Tim. Wine is a Linux application that allows you to run many Windows applications on Linux. See www.winehq.org
Adobe DNG converter works with it - on Linux
I understand. I guess it’s just a difference of opinion. To me, running Wine to run a Windows application is like running Windows, so I just don’t do it.

It has been a while since I worked with ProRAW and darktable. Or even did much with dt itself. So after finding I was a couple of dt versions behind, I took another swing at it.
Getting the files out of the phone has improved. Under all the export options of the picture, is one to “Export Unmodified Original”. I have Google drive enabled both on the phone and my Windows PC. Easy to drop the file on the phone, and it appears in the Google drive on my PC. Then I transfer it to whatever folder is appropriate. No need for lots of additional cloud interfaces or extra storage.
dt will display the embedded jpg in lighttable, but rejects the file in darkroom.
So, Adobe DNG converter to the rescue.
After, the initial result is terrible - extremely underexposed. Exposure needs to go up about 3.5+EV After some playing with a few images, I also had to do some tweaking of Color Calibration, Color Balance, filmic, and local contrast additionally. This got me to a generic saved style that I can now apply to all converted DNG’s. While not one size fits all perfect, at all, it gives a reasonable starting point to better refine the picture as needed. Or at least have something that looks semi-reasonable, even if I have no interest in making it better.
