Description

Revision 1960 added ShutterSpeedValue to the TIFF/EP tags, but its type was set to unsignedRational. I believe it should be a signed rational (see e.g. http://www.awaresystems.be/imaging/tiff/tifftags/privateifd/exif/shutterspeedvalue.html).

I am attaching a patch against svn trunk.

History

Updated by Andreas Huggel almost 12 years ago

I used a draft version of the TIFF/EP standard where it is an unsigned rational.

But that seems to be an error as it is in APEX units and supposed to be the same information as Exif.Photo.ShutterSpeedValue.
