Re: Reading EXIF AUX values

Hi,

are you looking at a raw image file?

The XMP toolkit currently doesn't support raw image files whereas Photoshop does support raw image files through Camera Raw. That's probably why you can see aux properties in Photoshop's FileInfo dialog.

For JPEG files the body serial number is part of the EXIF standard since EXIF version 2.3. The XMP toolkit will map this property to exifEX:BodySerialNumber (exifEX="http://cipa.jp/exif/1.0/"). For compatibility reasons exifEX:BodySerialNumber will also be mapped to aux:SerialNumber for reading and writing JPEGs.

So if you can't read aux:SerialNumber through the XMP toolkit you either have a raw image file, the camera doesn't support EXIF 2.3 or the camera doesn't set the BodySerialNumber tag.

Thanks,

Jens
