Re: [darktable-user] Philosophical question

What do I lose converting from CR2 RAW files to DNG? I always
shoot raw but is there a benefit or a degradation to converting to
DNG for future proofing my images?

What I recall reading on the list is generally against conversion to 
DNG. My understanding is that a) the format is being changed - so there 
is a chance something to not work as intended and b) some tags in the 
original RAW that are not used "now" may become useful in the future. 
Converting to a different format would loose these tags. I personally 
don't use DNG so I can't say anything about possible benefits.

B

Personally, I'm OK with converted CR2 → DNG, it works fine from my
experience. But I have problems with NEF → DNG, there is some problem with
maker notes interpretation in exiv2 (used by dt) which leads to problems in
lens detection (hence no automatic lens correction). I know that some
developers
 strongly oblige against conversion, but I find it useful on big
collections — 15-20% size reduction does matter for me.

If this is off topic I apologize.

Answering part of mine own question. Converting to DNG solves the problem but I don't know what I'm losing converting to DNG.

I've not seen this before, but admittedly since I switched back to Canon, I don't have a lot of Nikon NEF files left.

 

Is this a known issue? If I convert the NEF files to DNG will that resolve the issue with reading camera white balance?
