Hi,
I'm using PIL to process jpeg images according to EXIF tags. It works
great except that I can't access the ExposureBiasValue tag. I tried
images from a Sony H9 and from a Nikon L10. I uploaded one of the
offending pictures on my website:
http://ygingras.net/files/dsc01970.jpg (2.2MB)
Digiakam, exiv2, and EXIF.py all read the ExposureBiasValue properly:
-1.0. I looked at the code in PIL/JpegImagePlugin.py but my limited
understanding of the EXIF format prevents me from seeing any obvious
bugs or to compare with another implementation.
Anyone else have this problem? Is there a workaround?
