Who here converts their raw files to .DNG? What do you think of the format?

DNG is fail because no big camera manufacturers except Pentax support it, it's xbox hueg, and there's no guarantee it's going to be widely supported in the future.

I store my photos in plain q=11 JPGs after post-processing since I rarely need to manipulate them later to the extent that JPEG losses become significant.

Avoid. AIDS be there.

The few CR2 files I have converted have all been smaller in DNG format...

I think usually DNG > RAW > compressed DNG > compressed RAW > lossy compressed RAW (since manufacturer-specific RAW compression should be better than general-purpose compression in DNG)

I just tried meddling with ACR:
14127616 P7144692.ORF (uncompressed source RAW)
17121316 P71446921.dng (uncompressed DNG)
8782432 P7144692.dng (lossless compressed DNG)

Oh, I remembered that I have some compressed RAWs too. These are from a different camera, though

11480434 P.ORF (lossless compressed original RAW)
21742044 P1.dng (uncompressed DNG)
11769310 P2.dng (lossless compressed DNG)

So basically compressed DNG is only useful if your camera can't output compressed RAW and you want to save a bit of disk space; uncompressed DNG is absolutely useless. Uh, and wake me up when they start taking DNGs for printing.

For the average Joe, DNG is one way to be able to work with your raws in Linux (e.g. GIMP, ImageMagick etc).

I can't think of much other reasons to convert out of native format unless you have some ultra complex workflow (e.g. Lightroom on a laptop in the field -> DxO Optics on a desktop PC -> Publishing software) but most of the time you'd just use 8-bit or 12-bit TIFFs or something... I guess.

Unless your camera is a Pentax, you still need some Windows or Mac software to convert your native RAW files, which kinda defeats the point of using DNG.
Plus, GIMP already supports quite a few native RAW formats with ufraw, IIRC.

I use ufraw for my Pentax RAWs, but I use it externally to convert them to JPEG first.

I think you can use it as just a loader, but I'm sure even then it still converts them before you load it in Gimp.

.DNG and dedicated RAW button... I love my K10D :)
