exifread return incorrect value

[RhoLuke]

Hi, i'm trying to extract the exif valies from a raw image, the exifread function process_file seems to work, but some tags are incorrect.
I report an example below:

exif = exifread.process_file(file, detail=False)

if I type
exif['Image Orientation']

I obtain the following output: (0x0112) Short=Rotated 90 CW @ 78

but if I type exif['Image Orientation'].values
I obtain the following ouput: [6]

What about exif['Image Orientation'].printable ?
