Image rotation

[BTreeTech]

I am trying to correct image rotations (portrait or landscape) when displayed in a report back in the office using QGIS
I found some very useful reading in this post
We are using Ipads
I have disabled "use native camera" so I now get tagged photos
I can get a map of the exif data using exif(@project_folder + '/' + "Photo2")
The Exif.Image.Orientation tag is always set to 6 (6 = Rotate 90 CW) regardless of the orientation when the photo was taken - from my testing
Any ideas why the orientation is always 6 ?
is there another way?

According to this link 6 means photos taken in portrait mode with iOS. It means "rotate 90 CW" is from a landscape by default.
You don't tell us if your photos have been taken with different orientation or not, resulting with only this "6" orientation or if all the photos are just mis-oriented (landscape instead of portrait), which could mean you have to make a formula to change this 6 to 1 (exif.Photo.Orientation minus 5 for example).

The Exif.Image.Orientation tag is always set to 6 (6 = Rotate 90 CW) regardless of the orientation when the photo was taken - from my testing

• I tested with various photos taken in different orientations

[VxTedxV]

Do you confirm it's not QField related then ? Your device always produces EXIF tags with this '6' orientation, even when photos taken outside QField ?

[BTreeTech]

I haven't tested photos taken outside of QField, I need it to work with photos taken in QField using the QField camera. I think the native camera doesn't tag photos with much.

Image of some of my testing.
I also tested on Android and the rotation is always 0, again using the QField camera

Upstream issues.

For Android, it was fixed (https://bugreports.qt.io/browse/QTBUG-118236) and will be part of QField 3.4

For iOS, follow this issue: https://bugreports.qt.io/browse/QTBUG-118594?filter=-4&jql=text%20~%20%22qml%20camera%20orientation%22%20order%20by%20created%20DESC

@nirvn thanks for the clarification, my original discussion does ask for ideas on other ways of making it work so not sure why this was changed to a bug and closed

[nirvn]

@BTreeTech , I doubt there's much of a workaround here. In the meantime, did you try a development build that will become QField 3.4 to see if the problem is indeed addressed as per upstream reporting? You could give the APKs here (#5514 (comment)) a try on an Android phone.
