[Openexr-devel] Adobe's Digital Negative Format

[Derek Gerstmann]

Adobe has proposed a new Digital Negative (DNG) File Format:

Although their goals are oriented more towards being adopted by the
digital camera industry, it seems silly to introduce yet another
proprietary image format (DNG becoming the PDF of digital images).

Wouldn't an open standard such as OpenEXR be a better choice?

Or is it simply impossible to convince camera manufacturer's of the
advantages?

I thought Greg Ward's analysis of all the major HDR image encoding 
formats covered this quite well:

What does DNG have to offer over EXR (granted EXR was developed
as a means of storing scanned film footage, rather than direct
capture of CCD data) other than Adobe being behind it?

I suppose it mostly marketing, but I for one would enjoy
the ability to capture images natively in EXR.

...

Sorry if this is offtopic for the developer's mail-list, but I
thought it might be of interest to many of the members on this
list.
