So far ImageMagick does not not do any color correction to the DNG image. We need to investigate the conversion process more. In the mean-time why not post a URL to your DNG image and the original raw format or in JPEG so we can investigate the problem.

DNG - Only Thumbnail size

Post by Armani » 2006-01-26T07:01:56-07:00

hi, i got the same effect when working with DNG files.
All I can get is a thumbnail size image out of my DNG files. (256px)
Even identify tells me that it's only such a small picture.
I'm using a Canon EOS 350D and converted the images with adobe's DNG converter version 3.3.

You can download the original Canon-Raw File from that url

and the converted DNG here

Maybe one can give me a hint what the problem is.

We leverage the TIFF delegate library to read DNG images. It apparently only sees one image in your file although it appears there is more than one. Looks like more work is needed before ImageMagick fully supports the Digital Negative format.
