[Leica] DNG

[robert.rose at mac.com (Robert Rose)]

Jayanand,

I think there is some confusion here, as the text you quoted pertains to 
?converted? DNG files, which I understand as a file that started life as 
something else, such as a NEF Nikon raw file, and then was converted to DNG 
by some Adobe product, such as Lightroom.  I am not surprised that DxO would 
not want to touch that.

All I do know is that the native DNG format from my M9 works great in 
Lightroom, previews just fine on my Mac, and is what I shoot.  Anything that 
I need to do with a photo in my workflow I can do in Lightroom, and DNG 
gives me the most latitude if I need it.

All the best,
Bob Rose

> From a Nikon list about DNG for what it is worth - I have no idea if it is
true or not. I do not use DNG format, so it is of little concern to me, but
those who do might want to check it out:

Worth noting that DxO Optics Pro does not (cannot, will not) open DNG files
for the following reasons:

"Regarding DNG files. We do not offer currently support for converted DNG
files in Optics Pro or any of our other produces. Though DNG converted
files contain the original RAW file information, the information is no
longer exactly as the camera body wrote it. RAW files are encrypted by
their manufacturers, and in order to use the information in these files, we
must decrypt the information using precise information provided to us. To
do this, it is critical that the information in the file be exactly as it
was written by the camera, down to the exact location of the data within
the file. When you convert the original RAW file to the DNG format, the
decryption information we have fails because the data has been moved.
Optics Pro is a far more precise program than the other programs you noted,
so it is imperative that all information be as the camera originally wrote
it to your camera card. Therefore, we currently do not have any immediate
plans to offer converted DNG support for input files.  DxO Support Team "
