Bug 451917

Summary:	Converting RAW (from CANON RP) to DNG produces files not useable in Rawtherapee

Description pastorale.ks20 2022-03-26 08:17:50 UTC

SUMMARY
If you convert a raw file created with Canon RP to dng, it not only different to dng created with Adobe DngConverter (at least the preview), you can use this dng only in darktable, in rawtherapee the colours are a totally mess. The dng from DngConverter works as expected.


STEPS TO REPRODUCE
1. start digikam add raw a file to a queue
2. select convert raw to dng
3. run
4. create another dng from the same raw file with Adobe DngConverter
5. compare the preview of both dngs
6. open both dngs with darktable and rawtherapee

OBSERVED RESULT
the dng created with digikam shows totally false different colours in rawtherapee, the dng created with adobe shows correct colours.

EXPECTED RESULT
the dng created with digikam should also work with rawtherapee.

SOFTWARE/OS VERSIONS
Manjaro 21.2.5
Qt Version: 5.15.3
Cinnamon desktop

ADDITIONAL INFORMATION

Comment 1 Maik Qualmann 2022-03-26 11:44:20 UTC

I downloaded a Canon RP RAW sample image from the internet. Converted to a DNG file with digiKam. I can't find any problems with RawTherapee. Likewise with Darktable or digiKam itself.

RawTherapee-5.8
Darktable-3.8.1

I think we need a RAW and DNG sample pair from you.

Comment 2 pastorale.ks20 2022-03-26 15:59:53 UTC

I can only attach files <4MB...but the files have >30MB. Is there another way?

Comment 3 Maik Qualmann 2022-03-26 17:40:43 UTC

Use an upload service like Google Drive or similar. Otherwise maybe try in 2 parts to my email address.

@pastorale.ks20@gmail.com,

digiKam 8.4.0 pre-release now include last DNG SDK 1.7.1 from Adobe.  Can you reproduce the dysfunction using AppImage bundle available here :

https://files.kde.org/digikam/

Gilles Caulier

Comment 8 pastorale.ks20 2024-04-07 16:04:32 UTC

For RP/CR2 it's the same error like before. For a newer camera (R6m2/CR3) it works.
I had a picture of each camera in a queue, but after a single conversion digicam crashes, even if there is only one picture in the queue.

Comment 9 caulier.gilles 2024-04-07 16:08:56 UTC

Using a cloud web-service, can you share the problematic files to test here ?

Comment 10 Maik Qualmann 2024-04-07 16:51:09 UTC

I can't find any RAW images in CR2 format for the Canon EOS RP on the web. According to the web, the RP should only create CR3 RAW images. Are you sure about CR2?

Maik

Comment 11 pastorale.ks20 2024-04-07 17:28:55 UTC

@Maik:
Yes you're right...I mixed it up...
But I've sent a download link to your gmail account.

Comment 12 Maik Qualmann 2024-04-07 17:30:49 UTC

I can already reproduce strange crashes in CR3 RAW files in the current git/master version, at the end of a DNG conversion, but also when setting a rating, for example, although writing with ExifTool is not activated. It crashes here:

Digikam::ScanController::beginFileMetadataWrite()

Comment 13 Maik Qualmann 2024-04-07 17:33:57 UTC

Ok, something is broken here at the moment, it also crashes when writing to JPG files.

Comment 15 Maik Qualmann 2024-04-08 08:37:33 UTC

Thanks for the download link. The RAW can be converted to DNG in digiKam, it looks ok in Darktable. Not in RawTherapee. It is too dark, when RawTherapee performs automatic tonal correction the color breaks out.

I've already done some tests, no metadata copied into the DNG etc. The problem remains.

@Gilles, did you also get the download link?

Maik

Comment 16 caulier.gilles 2024-04-08 09:03:54 UTC

Hi Maik,

no download link in my mail box ...

Comment 17 pastorale.ks20 2024-04-08 09:33:03 UTC

strange - i've sent you two links yesterday...

Comment 18 caulier.gilles 2024-04-12 05:34:25 UTC

First the CR2 sample open fine in digiKam 8.4.0 (thumbnail and Raw Import) :

Comment 19 caulier.gilles 2024-04-12 05:36:00 UTC

JPEG preview extraction is fine too :

Comment 20 caulier.gilles 2024-04-12 05:39:35 UTC

Conversion from CR2 to DNG using DNG SDK 1.7.1 work fine :

Comment 21 caulier.gilles 2024-04-12 05:41:33 UTC

Resulting DNG file loaded in RAW Import tool work fine too:

Comment 22 caulier.gilles 2024-04-12 05:44:33 UTC

Preview of both files sounds fine in RT 5.9 :

Comment 23 caulier.gilles 2024-04-12 05:50:47 UTC

I confirm that RT editor show an under exposed version. No idea why ?

Comment 24 caulier.gilles 2024-04-12 15:12:20 UTC

In opposite, Darktable 4.4.2 thumbnail is not too bad :

Comment 25 caulier.gilles 2024-04-12 15:14:23 UTC

In darktable editor, the rendering is exactly the same :

So, i suspect a RawTherapee problem...

Gilles Caulier

Comment 26 caulier.gilles 2024-04-13 10:27:58 UTC

I installed the last Adobe DNG Converter application for macOS and converted the CR3 file to compare with the digiKam version. In Rawtherapee the rendering is better :

I stored the both DNG files (digiKam and Adobe) in this area :

Comment 28 caulier.gilles 2024-04-13 10:34:55 UTC

On the Google Drive repository, i uploaded the Exiftool contents of metadata from the digiKam and the Adobe DNG files. the digiKam one as a double size against the Adode...
