How to get an exif value in Python

Hello everybody,

i am just sitting some hours on this problem now, and i can't get it solved:
- how can i access an exif tag from a python plugin?

I a not able to get the exifdata like this:

myimage = window.get_image()
myexifdata = myimage.get_exif_info()

get_exif_info() is an unknown function...

What am i doing wrong?

Thanks for your help!
