How to Rotate Image?

[Mick Sulley]

Hi, I have several pictures taken with my old camera that should be in
portrait and they display in landscape.  Looking at picture from my new
camera I see that pictures taken in landscape have EXIF Orientation set
to top, left, whereas pictures taken in portrait are set to left, bottom
and they all display correctly.  I assume that to 'fix' the pictures on
my old camera I just need to change the Orientation setting.  I can see
loads of EXIF data that I could edit using Image>Metadata>Edit all
Metadata, however Orientation is not there.  How do I edit Orientation?

Or is there a better way to do it?

Thanks
Mick

Can't you just select the pictures with the same orientation and hit
the rotate button?

Cheers,

Dear Johannes,
 it may also be necessary to set manually exif-orientation-flag to "normal"
after rotating the picture

Dear Johannes,

I asume you are german, so I will tell you the german translation.

 

Select all pictures that need to be rotated

 

Menu -> Bild -> drehen -> links (oder rechts)

 

Pictures are still selected

 

Menu -> Bild -> Exif-Ausrichtung Justieren -> normal

 

 

Or

 

Menu -> Bild -> Exif-Ausrichtung Justieren -> links gedreht (or whatever)

 

Menu -> Bild -> Automatische drehen nach Exif-Information

 

 

Regards Volker

As far as I know, this is an old bug that deasapeared around digikam 2.6

there is also an option to change the exif tag when rotating, but this
orientation is still a nightmare, because you can also have the tag
kept and digikam orienting the image on the fly, so you don't even
know it was differently oriented

in fact nobody should ever have to touch this tag, but not all
software do the job right

I am using 2.6.0 , seems to be very buggy on this topic.
