Convert to DNG reversable?

I was thinking of going all out and converting all my CR2s to DNGs. However, if I include the original CR2 it makes the file almost twice as large, so I don't want to do that. If I convert to DNG withOUT including the original, can I ever get it back to raw? And if yes, how?
Thanks

And its not just camera manufacturer software - there are many other non-camera-mfr/non-Adobe softwares that either don't support DNG at all, or say they support it, but then they won't read your Adobe DNG files! (of course its not their fault..., but still......)
I say: "Never delete your originals".
PS - If you've still got your originals, then the conversion is somewhat reversible:
1. Flush all your edits into the xmp metadata of your DNG files by using Ctrl/Cmd-S (select target photos first).
2. Use exiftool to extract the xmp metadata from your DNG files into xmp sidecar files - xmp sidecar base filename must match your originals.
3. Replace the DNGs with the originals.
4. Do a folder-sync (imports all the originals and applies xmp metadata from sidecar files). - You can delete the DNGs from the catalog during this phase, or leave them in with missing sources for awhile.
You'll lose everything thats not in xmp, like virtual copies and collection affiliation, since the originals will be looking like new files to the catalog. But it will preserve edits, keywords, ratings, ..., since this stuff is saved in xmp metadata.
There may be a plugin, and if there isn't, then there should be, that preserves all the other catalog data too, and if not then there will be and you may want to wait for it - the tools that make it fairly easy for a plugin to do have only been available for a short time.

Is it wise to keep the Nikon camera files "DSC's" after downloading them and converting to DNG files via Adobe converter for lightroom use. In other words do the DNG files have all the raw data I would ever need in processing or should I save the camera'

Is it wise to keep the Nikon camera files "DSC's" after downloading them and converting to DNG files via Adobe converter for lightroom use. In other words do the DNG files have all the raw data I would ever need in processing or should I save the camera's DSC files?

DNG files do not contain some metadata supplied by the camera, which can be used by the manufacturer's software. Thus, if you don't keep the original Raw photo, you will lose this information.
If your 1000% sure you're never going to use the manufacturer's software, then this isn't a problem. But who can be sure what software you will be using 10 years from now?

Adobe Bridge CS4 - "convert to DNG" not working?

Hi
I am downloading a bunch of raw .CR2 files taken with a Canon 5D mark iii, and trying to convert them to DNG using Bridge, so that I can open them up in Camera Raw (which won't read the original CR2 files as you need CS5.5 or later). I have selected the "convert to DNG" option but the conversion doesn't seem to work, it's just copying the CR2 files over, Any idea why?
thanks

I have selected the "convert to DNG" option but the conversion doesn't seem to work, it's just copying the CR2 files over, Any idea why?
It seems you are using Photodownloader that comes with the CS version you are using currently. This Photodownloader is linked to the Raw converter of the version it is part of. So if it does not show the CR2 files as images it also won't convert to DNG
For this you need to download the latest and Free Adobe DNG converter.
Check this page, there is also an option to download the converter for either Mac or Windows

Convert to dng is greyed out in CS3 Bridge Photo Downloader

I have no idea what has happened, but when I use the Photo Downloader in Bridge (CS3) to copy using my card reader, the option to convert to dng is greyed out and is not available for me to select. I can convert to dng using the stand alone dng converter and also from within Camera Raw with no problem, but I like the convenience of doing the conversion using the Photo Downloader. This option was available to me and worked perfectly up until a couple of weeks ago. Any ideas and suggestions will be greatly appreciated. thanks in advance.

PSE8 for Mac: Convert to DNG in Bridge Photo Downloader fails

Using PSE8 for Mac. When I get RAW photos from Bridge and specify "Convert to DNG" in the advanced options of the Photo Downloader, the RAW files download but the conversion to DNG fails for every image. I can successfully convert using the standalone DNG Converter, but I would like to use the option in the Photo Downloader that comes with Bridge. I'm in touch with Adobe Support on this but not having a lot of luck. Has anyone had this problem or know what to do?
Also, I cannot see the RAW images either in the Photo Downloader or in Bridge. They show up as blue squares with a flower graphic on them in the Downloader, and as white squares in Bridge. I can only see images once I open them in Elements. Is this normal?

Also, I cannot see the RAW images either in the Photo Downloader or in Bridge.
This is the source of your problem. You need to update the raw converter in bridge, which ships with a very old version (5.0). In bridge, go to help>updates and let it do its thing.

Convert to DNG not available in Bridge photo downloader?

All of a sudden when I try to upload RAW photos from my Nikon D5100, "Convert to DNG" is shown in grey and will not let me select it in the photo downloader. I am having to use an outside converter instead. Also, the Camera Raw application is acting up - not letting me open images with Command + R, not saving image ratings of 5 stars, etc. Any ideas on how to resolve these issues? I am guessing that they are linked...

It was all of a sudden...randomly and not after an upgrade as far as I am aware.
Since you mention 10.9.3 which is a recent update it may well be caused by this update. Read the article Yammer provided and try that. Also as described in earlier post, restart Bridge holding down option (alt) key and from the menu choose reset preferences.
But there have been some problems with recent ACR and DNG in photodownloader that should have been solved with latest ACR. So also try the manual download and install of the link Yammer provided.

How do I convert to DNG for CS3 without demosaicing?

Recently purchased the Sigma 60mm 2.8 lens for my Sony NEX-6, which shoots ARW raw files. When converting to DNG (using the newest 8.2.0.94 version), the files increase in size from ~15MB to ~60MB. This appears to be because I have the compatibility settings set to Camera Raw 4.6 compatibility, and the converter believes this means it has to demosaic the image. This is done with no override and no warning that information is going to be discarded, despite the fact that I shoot raw files because I want raw data. How can I produce DNG files compatible with Photoshop CS3 and Camera Raw 4.6, without discarding data and producing huge files?
This is doubly frustrating since manual lenses convert fine. I do not care about any lens correction information in the original ARW files, as only very minor corrections are needed anyway. Losing this information to produce good DNG files is perfectly acceptable to me.
Similar threads show that newer versions of DNG can be converted to without the demasaicing being applied, but this is not helpful to me. See http://forums.adobe.com/message/4312768, http://forums.adobe.com/message/3333887.
I have no plans to upgrade photoshop (especially the CC versions), so need something that works with CS3.

Okay, so I lied. I'm going to answer one more time. In my opinion, it isn't necessary to change your "entire workflow". Take the example of a panorama image. As in ACR, I make adjustments to the raw images using Lightroom. Of course, I have imported those images so I'm able to see that folder of images in my Lightroom library. Lightroom has an adjustment where I can highlight all images and choose to "match total exposure". I have found that using that really simplifies the merging to panorama process.
When I have done all that I need to do in Lightroom, I highlight all the images and choose the option to merge to panorama. Photoshop opens, the images that I've highlighted transfer to Photoshop and the panorama dialogue appears listing those images. I set my options and let Photoshop build the panorama.
When I'm through with Photoshop I save the panorama image and return to Lightroom. The panorama is there automatically added to the catalog. I can take that image back to Photoshop if needed. And I can export images in different formats for different purposes. But I only have the master images and the one panorama that I have to maintain. If changes are decided upon in the future I only have the one image to worry about.
The postprocessing in Lightroom is much more elegant (in my opinion) than ACR. You know, you can download Lightroom and try it for 30 days and see what you think. I still believe you are anticipating much more change than is really necessary. So my original answer still stands.

Trouble with CR2 and converting to DNG

I am new at using camera raw files. I recently got a Canon EOS Rebel XS/1000D as well as Adobe Lightroom 3. I tried loading my CR2 files into Lightroom by "copying as DNG." Once I did this, the program said "the files are from a camera which is not recognized by the raw format support in lightroom." I then tried downloading the latest DNG converter from Adobe.com to convert my files, but this program also said "the source folder does not contain any supported camera raw files." The third route I tried was loading my photos into brindge directly from my camera and checking "convert to DNG." This did not work either. When I looked on Adobe's website, I saw that Camera Raw 6.3 should be downloaded for Lightroom 3, but it is not compatable with CS4. I did not do this because I did not want to interfere with the other CS4 programs and I am not sure if this has anything to do with it (I have camera raw 5.7 I beleive) I have also tried saving my photos to my computer, then importing them, as well as directly importing them from the camera into Lightroom.
Can anyone help me with this? LIke I said, I am very new to using camera raw and Lightroom and I am not sure what I am doing wrong.

also, I am not sure why the size of the photo was so small. Could this be part of the problem?
Almost certainly. I suspect the file got truncated. The header info is there, but it looks like most of the image data is just missing.
Buy some new good quality media and do not trust the card these images came off of until you can verify them. Even if the media is suspect, a card reader might have better luck extracting all the data, so just put the media away and look at it later.
I've said it before, but it bears repeating. It isn't about /if/ your media or hard drive will fail, but /when/. Flash media is tricky because it can go bad in really inconvenient ways like this. Pro cameras are starting to accept dual media so you can at least have a JPEG copy on the other media if the raw write fails. But, as suggested elsethread, ALWAYS format the media in-camera so that the firmware on the card can spread the writes out over the entire card over time, and map out bad spots as they occur. And they always occur. Flash media starts to fail the moment we buy it and stick it in the camera.

Convert to DNG doesn't work in Bridge with 5D mark III

I'm using CS6 and the 'Convert to DNG" option doesn't work when I download my Canon 5D Mark III files, but it works with my 5D Mark II files. HOW can I get this to work. I've had to convert using the DNG converter.

Update ACR to 8.7.1 and you won't have to convert to DNG at all. the 8.7.1 DNG converter also supports the Mark 3.

Sony RX100 raw files converted with DNG converter not recognizable

Since installing Maverick 10.9.4 on the Mac, Sony RX100 raw files converted with DNG converter are no more recognizable.
Somebody else the same problem?

I know my DNG files themselves and the info they contain are fine. But they're not properly supported in Mavericks 10.9.4 and I don't plan on switching to Windows. A file that I converted to a DNG using Adobe software is now listed as an unrecognized file in OSX. No thumbnails, no iPhoto, no Aperture. Essentially, no support. And this is a problem. A quick search will show you people with various Sony cameras (A7, RX100 mkI and mkIII, at least) having the same problem.
No matter where the blame falls, the simple fact is that if you shoot with various Sony cameras, use Adobe software to convert the file to DNG and happen to be an OSX user, you're files are no longer compatible with OSX or Apple's photo software. They will only open in Adobe software. You literally get a warning message from OSX saying, this is an unsupported file type when you try and open it.
Like I said previously, I've had a managed iPhoto library for about 5 years now, numerous hours of tagging and organzing, and every DNG file converted from a Sony ARW RAW is currently unsupported. Original ARW files work just fine. It's nuts. Maybe it's Adobe's fault. Maybe it's Apple's fault. It really doesn't matter. If DNG is not a reliable standard format under certain edge cases (Sony ARW, DNG converter, OSX Mavericks), it's not a reliable standard format at all. I just hope that Apple or Adobe figures this out, so that I can get those photos back.
In the mean time, certain users such as myself just can't rely on DNG. End of story.

Fujifilm raf converted in dng

Shooting in raw, I have always converted to dng the raw files of my successive Canon DSLRs upon importing in Lightroom. The dng files were roughly the same size of the orinal raw file and I was able to directly open these dng files in many applications on my Mac: Preview, iPhoto and Photsoshop CS4.
I recently bought a Fujifilm X-E1 and I was surprised to discover that
1. as the original raw files are always 26.1 Mb, the corresponding dng file is roughly the double (between 47 and 59 Mb);
2. even if the Mac and its native applications (Finder, Preview, iPhoto) recognize Fujifilm raf files, they don't recognize the converted dng files (on the contrary, Photoshop CS4, not surprisingly, doesn't recognize raf files but recognize the converted dng files).
So, even if I was convinced that converting to dng had some advantages, considering the above disadvantages about the conversion from the new raf files, I think I will use the raf files without converting them to dng.
What do you think of that? Do you have some further explanations?

I have exactly the same issue!
For what it's worth, i found the way to fix it for new imports. (using LR5, by the way).
When importing the files, don't select embed raw data, and do not chose 1:1 previews. When I select standard previews, I in fact, get a smaller file than my RAF (from ~22 -> 18-16mb)
My problem now, is, how do I "RECONVERT" those 50-55mb DNGs using the above settings on 3000 photos I have already taken! I'd very much would like 80GB back!
Any ideas?

Why doesn't converting a DNG with a later converter update metadata?

Example:
Convert a 7D CR2 with DNG Converter 5.5. This gives certain values of metadata such as color matrices & white level.
Now convert that same CR2 with DNG Converter 5.6, and this gives different values of such metadata. (That is reasonable. After all, 5.5 was a beta version as far as converting 7D CR2s was concerned).
Now convert a DNG output by DNG Converter 5.5 with DNG Converter 5.6. (You can use the DNG Converter on old DNG files, of course). The metadata in the new DNG remains with the original 5.5 values.
Why?
Why not, as least as an option, generate the latest metadata? Don't we, in future, (at least as an option) want to be able to use the latest DNG Converter to bring our old DNGs up to the latest state?

Your old one is physically incapable of running Siri. This is akin to a person being upset that their 3 year old DVD player can't play BluRays...i mean the disc fits in the try so it should work right??????
ANd honestly, I've had Siri on my iPod and I think I've played with it twice. It has to be on the internet to be used so unless you have a 3G device she's inaccessible much of the time
You gotta have siri, buy a new device. Your iPad 2 will NEVER be able to handle the software.

Should I use default Raw or convert to DNG?

Hello,
I have olympus SP570UZ and use LR 3. I'm not a professional photographer but do a lot of photography and shoot in raw. My question is should I use the default raw file for import/editing or should i convert to dng? does it effect editing capabilities and degrade the result when i convert to dng?
I work on laptop and it seems a lot slower in loading default raw files. Will this improve my overall work time and lower load on cpu and space, but my first priority is picture quality?
Thank you.

Converting to DNG is really a matter of choice not necessity. If your camera is already supported by Lightroom / Camera Raw then there is little to be gained by converting the images to DNG at the beginning of your workflow. Many who champion DNG will keep their images in the camera vendors raw format until they've completed their edits and only then convert the final image to DNG.
In answer to other questions. Performance - DNG is not some magic bullet that will increase the performance of your family saloon into that of a Porsche. Space - The lossless compression used by DNG is more efficient than that used by the majority of other raw formats, but only saves space if you trash the originals after conversion. (Note - trashing your original raw files is not something that I would ever recommend let alone suggest.) Quality - There should be no difference in quality between the original raw file and the DNG version.
FWIW, DNG was originally proposed as standard "capture format" but as time has gone by and few camera vendors jumped on board Adobe's position has changed to "DNG is ideal as an archiving format". The latter is probably the less time consuming and more future proof approach. As mentioned above,it's also the approach adopted by many of those who champion the DNG format.
No doubt someone else will come along and add their tuppence worth for one or the other, but if previous threads on the same subject are any guide you'll still be left wondering. Try typing your original question into Google and see the mass of info and opinion that already exists. I can hear the sound of Hornets buzzing already.
Disclosure - I use DNG not raw throughout my workflow. This means that my thumbnails and previews accurately reflect the Adobe rendering in all of the applications "I" use. "I" don't use the camera vendors software (i.e. Canon DPP), so have no issues with the fact that it does not support DNG.

Convert to .DNG at Tethered Capture?

Is it possible that Lightroom V5 can convert to DNG upon ingest of tethered capture images? In other words, when I'm tether shooting, can the image I capture show up in the Library already converted as a .DNG? This would be optimal for my workflow, rather than have to export my native camera raw file as .DNG after the session is completed. Would love to know if this can be accomplished.

Does any know ?

Converting to DNG after editing.

Is there any way to convert raw files to DNG after they have been edited and preserve all the edits in DNG?
I have to say I never converted anything to DNG before. I just tried to convert a few files and all the edits have been discarded.

Yes, just use the Library menu command to convert to DNG.
LR keeps the same development and other metadata instructions as it had for the proprietary raw image.
If you want to this outside LR, you need to save it to xmp, so do a ctrl s after the conversion.
What exactly did you lok at when you said the edits had been discarded?
