[digiKam-users] dk 6beta2 portrait orientation problems

[digikam-2]

Converted yesterday from dk5.9 appimage to dk6beta2 appimage.

I just noticed a problem: all my portrait orientation images are
sideways:

How to deal with that?

Hi,

Welcome to the RAW shot world. You problem is well know, as you have post processed the CR2 files in your camera to rotate the preview in right orientation while previewing photo.

When you touch orientation of preview with camera, this do not change the RAW data but the JPEG preview image embedded inside the file.

The problem is : the JPEG image has no Exif info attached (where we found the orientation information in standard). The only information oabout orientation come from standard Exif from RAW metadata. Both image are different as you post-process orientation with camera. So now, digiKam is lost.

Perhaps this information from Canon JPEG preview can be taken from private RAW makernotes, i don't know.

Another solution will be to render the thumbnail with RAW data (using a simplified demosaicing to prevent time latency).

I would to know how software render the CR2 preview here ? Aperture, LR, etc...

Best

Correction:

It's not all the portrait orientation images that are rotated, but
the vast majority are, see:

Are sidecar files available? DigiKam now also recognizes modified sidecar
files if the modification date does not match that in the database. Eventually
a changed orientation comes from here as well. Also, LR sidecars are now
preferred, if they are available.

Sorry but I will have to disagree with you. dk 5.9.0 doesn't have the
problem:

dk 6beta2: https://i.imgur.com/W5bNhcM.png
dk5.9.0: 9709.cr2: https://i.imgur.com/kFfvkrx.png
dk5.9.0: 9726.cr2: https://i.imgur.com/0refWgf.png

I have also attached the xmps for the files. If you need I can also
provide the cr2 (canon-raw) images.

To me it seem that:

* 5.9.0 reads the image preview (b&w preview) and uses that for the
  thumbnails
* 6beta2 tries to process the image and use the resulting mini-image
  for the thumbnails

Thanks

Hi Maik,

I just read the thread and I don't understand how I can rebuild my
thumbnails. Maybe I missed something (according to my wife that
happens all the time).

Thanks

Further info:

The rotating is done by DK6beta2

1. I copied a all bunch of files into one of the directory "watched"
by DK6b2, including about 30 images in portrait orientation
2. DK6b2 first displayed the thumbnail in the portrait orientation
3. after a few seconds DK6b2 processed these images and rotated them
1 by 1 to landscape.

I'm not using DK for any image processing, I'm using Rawtherapee. Is
there a way of disabling image processing in DK?

Thanks

Does the problem only occur with RAW files taken in B&W?

No, it also happens with RAW files in colour. It happens with Pentax
(PEF), Pentax (DNG), Canon (CR2) and Fuji (RAF).

I usually (not always) shoot RAW with B&W/Monochrome preview (about
50%-to-60% of the time). The other 40% to 50%, the preview is colour.

I never do JPEGs directly.

Thanks

And your RAW images that you have already loaded with digiKam-5.9.0, are also
some of images rotated?

I'm not sure that I understand what you are asking.

Both 5.9 and 6b2 are loading the same photos located on: /drive-b/photos
(/dev/sdb1). I have a 5.9 database and a 6b2 database and I rename them
as needed for v5.9 or v6b2.

digikam4.db.59
recognition.db.59
similarity.db.59
thumbnails-digikam.db.59
digikam4.db.6b2
recognition.db.6b2
similarity.db.6b2
thumbnails-digikam.db.6b2


* The images that are rotated in 6b2 are not rotated in 5.9
* Most of the images have a B&W preview. The B&W preview is gone in
  6b2

Somehow in the thumbnail view, 6b2 is reading the the image preview
and processing it while still in the thumbnail mode. I never went in
the edit. I do not DK for any of the editing. I could see 6b2
converting the thumbnails from B&W rotated portrait to colour
landscape.

That B&W RAW thumbnails are rendered in color is already undone in git/master.
It was the desire of photographers who shoot in JPEG + RAW to see the RAW
image then the original and not the embedded B & W preview image. However, we
have 2 issues currently, not all B&W thumbnails are actually always B&W and
contain colored pixels from the compression. And to recognize the actual
orientation to the original RAW image. When Gilles creates updated packages (>
15.10.2018), the problem is fixed for you.
