There was a post back in 2008 from magick regarding image transfer information:
"The image transfer information is not available as an image property at this time."

Does anyone know if this has changed? I'm currently running 6.8.1-6 and don't see it as a property (identify -verbose)

Is there another way to access this information?

Have you tried accessing the information similar to the way EXIF info is accessed. see http://www.imagemagick.org/script/escape.php

DPX can hold up to 8 frames and each of the frames would have a transfer characteristic. We could create a property dpx:image[0].transfer-characteristic, dpx:image[1].transfer-characteristic, etc. We'll add it to the next point release of ImageMagick.

May I ask what other DPX properties are currently not being reported?

Download the ImageMagick source and review coders/dpx.c. You can then identify DPX attributes that are not currently tracked as image properties.

Would it be possible to also have the colorimetric characteristic also be reported in the next release? The transfer and colorimetric characteristics are my main concerns right now. I appreciate your very fast response and addressing of my initial response.

Thanks!
