SUMMARY
Not able to view some RAW images, like Nikon NEF. But Canon CR2-s, JPG-s, PNG-s opening fine

Konsole output is:

Same problem in KDE Neon (Gwenview version 21.08.1)

Comment 2 Lapineige 2021-09-04 11:56:06 UTC

Can you open ARW files ?

Maybe it's the same issue as in https://bugs.kde.org/show_bug.cgi?id=441018

Comment 3 vylu 2021-09-05 09:08:37 UTC

Not sure if issues are related (could be, maybe ARW format does not include small thumbnail preview, I don't know much about it). When viewing NEF files, gwenview shows only small preview. When opening ARW file, gwenview does not show anything at all, just says that it failed opening file.

Comment 4 AL 2021-09-05 10:40:29 UTC

There have been more bug reports and probably this is mimetype issue. Havent found no workaround and dont know when this gets fixed.

> maybe ARW format does not include small thumbnail preview

It does include a small (and a very small) thumbnail preview.

> When opening ARW file, gwenview does not show anything at all, just says that it failed opening file.

Then I have the same issue (documented here https://bugs.kde.org/show_bug.cgi?id=441018).

Maybe that's a common one between both of our reports…

And indeed, it searches for a TIFF file (see https://bugs.kde.org/show_bug.cgi?id=441018#c1), so there might be a mime type issue too. Same in https://bugs.kde.org/show_bug.cgi?id=441698
