Doesn't matter if I turn on the auto-save meta data at the catalog level or manually save it, nothing is saved. Very frustrating, don't know if this is a bug or what. Has anyone had issues like this?

Everything I read said to convert to DNG so did at every import. Just upgraded to LR3 and made an error on my first import and both the raw image and Dng images were side by side in my catalogue. As I went through cleaning up I realized that very often there was a very visible color difference between the two versions and I preferred the raw version. I use a Sony a850. What is with the difference? Started shooting raw and using LR2 last fall so am a novice. Everything I read said to convert to DNG so did at every import.

What I mean is, when photo competitions request your original raw photo as proof of how much edits you made or did not make.. will the DNG file be sufficient? Can someone create a DNG file that has had serious edits to it? YES! In Lightroom for example you can make a ton of changes to a DNG file and the changes are saved in the DNG file itself. So sending that to the competition will not work because they cannot themselves determine if that is the original or not. With a RAW file from the camera, the edits are saved in the XMP, so just send the competition the RAW file and not the XMP. Done. I got bit on this recently with a competition and it was quite frustrating! Now I have returned back to only using RAW files. It is unfortunate because I really love the benefits of DNG, but its not worth the risk again of possibly not being able to submit my photos.

Looking at my own list makes me sad... What have I become?! A tech nerd! A file format geek! A slave to compression algorithms and bit depths! A sad shadow of an artist who actually just wants to shoot photos but got cought up in the massive ropes and insane complexity of a gigantic spiderweb of ill designed technology... I feel sorry for myself. I feel sorry for everyone who just wants to be creative. ;-) Haha!

CR2 sucks. NEF sucks. I am an expert in image and video file formats and all I can say about those three formats is - the more time you invest researching and converting them and the more technical details you understand - the more frustrated you will become. Also there is no light at the end of this tunnel! My recommendation is: Shoot RAW Use an X-rite color chart to build a proper color profile in Capture One De-fringe and de-chrom.abb. and de-noise in Capture One Debayer in Capture One (Compressing the dynamic range) Save as 16Bit Tiff Load 16Bit Tiff in Dxo Optics Pro Auto correct vignettes and lens distortions in Dxo based on their lens database Save as 16 Bit Tiff Then: Open Photoshop CS3/4/5 Convert the 16Bit Tiff into an OpenEXR 16 or 32 bpc (Lossless) (~80 MB on a 5DMkII) OR: Convert the 16Bit Tiff into a 16 Bit Jpeg2000 (Jp2) (Almost lossless) (~ 6-20 MB on a 5DMkII) DELETE Tiffs and RAWs Save EXRs or JP2s on a local HD + on a NAS + on BluRay(And send those to your mum in case someone spills beer on all your HDs DNG sucks.

I am an expert in image and video file formats and all I can say about those three formats is – the more time you invest researching and converting them and the more technical details you understand – the more frustrated you will become.

My recommendation is:
Shoot RAW
Use an X-rite color chart to build a proper color profile in Capture One
De-fringe and de-chrom.abb. and de-noise in Capture One
Debayer in Capture One (Compressing the dynamic range)
Save as 16Bit Tiff
Load 16Bit Tiff in Dxo Optics Pro
Auto correct vignettes and lens distortions in Dxo based on their lens database
Save as 16 Bit Tiff

Then:
Open Photoshop CS3/4/5
Convert the 16Bit Tiff into an OpenEXR 16 or 32 bpc (Lossless)
(~80 MB on a 5DMkII)

OR:
Convert the 16Bit Tiff into a 16 Bit Jpeg2000 (Jp2) (Almost lossless)
(~ 6-20 MB on a 5DMkII)

DELETE Tiffs and RAWs

Save EXRs or JP2s on a local HD + on a NAS + on BluRay(And send those to your mum in case someone spills beer on all your HDs

I'm the person who originally asked the question about DNG. I was pretty much ignored...well I did get one response. I figured I'd go elsewhere to find answers. I was going through my bookmarks and came back here. Jeesh, so now you start to talk about it. I figure I have some reading here to do. I better get busy. Well, I’m eddie.
