           Summary: Relative (not absolute) exif orientation shortcuts
           Product: digikam
           Version: 1.9.0
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR

Version:           1.9.0 (using KDE 4.6.2) 
OS:                Linux

Exif orientation shortcuts are difficult to find and are absolute only.
It would be great to have something like cntrl-shift left that effectively
rotates the image 90 degress left of whatever it is now, by modifying the exif
orientation tag.  

Presently absolute manipulations are possible.  In other words one sets the
orientation to "rotated left" regardless of how it was already set. What I mean
is if it is already set to "rotated left" then the left rotation action should
set instead it to "rotated 180".

One option for this might be to have a configuration setting that lets the
usual rotation keys act on just the orientation metadata instead of the image. 
This behavior, separately from the existing absolute options, could then work
in a relative way.

A couple of related points
1)The orientation shortcuts in the shortcut editor are completely not obvious. 
One for instance one is just called "normal", The others are like "rotated
left". It is not at all clear that these are exif orientation modifications,
and for "normal" it's not even clear that's related to rotations at all.

2)"rotated left" actually means the camera was rotated left so the stored
picture is in fact rotated right and the outcome after setting the tag, when
interpreted by a viewer will be to rotate the picture to the left.  I'm not
sure there's a good way to solve that confusion though. 

I would think calling the shortcut "exif rotate left" (not rotated) would help
solve both confusions and would put "exif rotate normal" near "exif rotate
left" in the shortcut list.

Reproducible: Didn't try
