All my raw files are a deep dark purple

Processing
1

I am a long time Photoshop user but would love to get away from Adobe and have downloaded GIMP 3.0 to give it a try as I hear this version is pretty good.

So I have downloaded Rawtherapee to convert my raw files (Canon R5 mark II) and Rawtherapee opens the files but they are all a deep, dark purple. I’ve tried to correct it but nothing works. Colours are just completely off.

Looking online I only came across others with the same problem.

I’m running Sequoia on a silicon Mac.

Is there a fix for this?

Thanks.

libraw, the library that reads the cr3 files, does not yet support the R5II. For darktable unofficial builds with support exist but I don’t know about rawtherapee

Not yet? But the Canon R5m2 was released almost a year ago! This is bad.

I tried Darktable too but it says the files are unsupported. However, I’ll go look for those unofficial builds.

Thanks.

Hello, Levina!

For RawTherapee, there is a pull request, that might or might not be merged soon.

In the meantime, you can try ART, a fork of RawTherapee, that already supports R5 mk2.

Libraw unfortunately has a very slow release cycle as they push their paid raw tools before releasing the code.

I am currently still running my own builds Adding new camera support in darktable / LibRaw / ExifTool – Pandas Welt

Hi, welcome to the forum. Not addressing your original question, but I would suggest forget PS or GIMP to process your raw files and focus on learning how to do these in a dedicated raw processor such as darktable, raw therapee or ART. I personally am addicted to Darktable because its great parametric and drawn masks allow you to do stuff which required layers and masks in PS or GIMP. I am not sure if your R5 files would open in darktable but avoiding compressed raw files will improve the chances that they will open in FOSS programs.

Craw files just work fine in darktable at least. R5m2 files also in all variants when adding my changes

I downloaded ART and it opens the files and everything seems to work well. Of course the interface is different and the keyboard shortcuts are not what I’m used to so things are a bit confusing at the moment, but nothing I can’t get used to. It looks good. And going through the preferences I saw GIMP listed as an external photo editor! So definitely worth exploring this. Thanks very much.

Question, how do I multi quote here?

Thanks, Benjamin. I followed your link but it’s over my head. I’m just an end user. But impressed by your knowledge.

Hi, Terry. Thanks for the welcome.

Unfortunately I can’t forget PS or GIMP. I need a pixel pusher and raw converters aren’t it.

When I open a raw file from my R5m2 in Darktable it says the file could not be loaded due to “unsupported feature in file”. But no idea what that feature might be. They’re raw files, straight out of the camera and not processed in any way.

I’m new to this forum software and can’t find a way to upload a screenshot.

Darktable does not support the R5m2 yet unless you have a build with “my” patches

One workaround is to use Adobe DNG Converter to get DNG files. Just make sure they are not the latest version 1.7, which aren’t always supported.

Like this:

Select the text and click Quote. Repeat.

If it’s in your clipboard, you can just paste it. Otherwise drag the file into the editor window.

Black level for Canon raw files should be around 512 at low ISO or around 2048 at higher ISO.

The colour matrix will be wrong, but at least this workaround may be good enough until it is supported?

15

I don’t use RawTherapee, but can’t you just get the profiles from DNG Converter?

16

I don’t use RawTherapee enough to know where to add it now when it uses Libraw.

The matrix is already posted in the link above.

17

… and there are Windows and Linux binaries available for all “pull requests” as described in RawTherapee Pre-dev

If you want to learn ART more here are some resources:

A recent addition is The ART Book, highly recommended:

Thanks, but I would prefer not to use DNG files because I don’t like how Adobe renders colours. I always used the camera’s colour profiles but with DNG that is obviously not possible and the difference between the Adobe and Canon colour profiles is quite noticeable. DNG’s are also brighter. Adobe seems to think RAW files need to pop. But I want a neutral starting point and not a kind of pre-processed Adobe file. Plus DNG files don’t respect the c-RAW format so it doubles the file size.

And thank you for the pointers regarding the forum software. :+1:

Thank you. Appreciate the links.

Quick question: how do I turn off those badges?
