First up, hats off to @agriggio, ART is an excellent piece of work, and it’s ease of use and more importantly results have enabled me to avoid the Adobe shackles (I tried hard to come to terms with Darktable, but just couldn’t get consistent results out of it)
I had to reinstall my laptop at the weekend after a Mint upgrade ate itself, and installed 1.7.1 from the appimage. Processing is working fine, but when exporting portrait format photos to JPEG, they’re rotated left by 90 degrees - all else appears to be fine.
To check, I installed 1.2 from the PPA (latest version there) which I had been using. This of course couldn’t read the 1.7.1 .arp file, but I quickly redid the edit and exported the result , which was fine. I next tried the same image again in 1.7.1 (the older .arp being readable) and exported the image with no further changes, and it came out rotated.
Looking at the the EXIF using exiftool, the 1.7.1 version has the following:
Orientation : Rotate 270 CW
whereas the 1.2 version didn’t include the Orientation field at all. Landscape format photos from 1.7.1 have:
Orientation : Horizontal (normal)
The files are RAF from a Fuji X-H1 (Fuji 10-24mm lens), and the
Orientation: Rotate 270 CW is present in the source portrait files. Setting
Orientation to 1 (Horizontal) for the affected (exported) images renders them correctly so I suspect the image is rendered on batch export with any rotation pre-applied (plus any further rotation in the editing), but the EXIF orientation then overcompensates when displayed. I’ve looked for a setting to turn it off, but can find none other that possibly rotating the images in the editor to compensate, but this would screw up editing
