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?

Convert to DNG after import?

Is anyone aware of a good way (workflow, applescript, plugin?) to convert raw files to DNG after they're already in Aperture? In other words, is there a way--like Lightroom--to convert the files but otherwise preserve adjustments, versions, and other meta-data?

if the DNG file could not be displayed in Aperture, it means that the original RAW file format wasn't supported. IIRC, there are two types of RAW files, those that serve as a wrapper around the original RAW file and a "linearalized" format, where the DNG converter attempts to convert the manufacturer specific RAW data into DNG image data. Aperture doesn't support the linearalized format for sure and Aperture only supports DNG wrappers for file formats it supports natively.
at this point i think that advocating DNG conversion on a broad scale is a bit premature. even after several years of promotion by adobe, there is still no industry-wide adoption of the format. camera manufacturers need to start writing DNG right to the storage cards, then it will begin to become a true standard.

Convert to DNG after Lightroom adjustments

Hello,
I have a number of CR2 (RAW) files that I have made adjustments to in Lightroom. I would like to use the DNG Converter (standalone) to convert to DNG.
Usually, I convert to DNG before making adjustments...will my adjustments to the CR2 files be applied to the DNGs after conversion (outside of Lightroom using DNG Converter)?
Thank you
PS: Under what circumstances is it necessary to embed the Raw file in the DNG?

YTou don't want to use the dng converter. If you use DNG converter, you will lose all your adjustments and Lightroom will lose track of your files. Just use Lightroom to do the dng conversion. That will make sure the changes are kept and you will not lose the link in Lightroom. The option is in the Library menu. There is no difference in the generated dng file, so it is far more convenient to do it in Lightroom.
> PS: Under what circumstances is it necessary to embed the Raw file in the DNG?
Never. My advice is to if you really want to use dng (there are a few good reasons to do it, one is reduced file size, but also a lot of good reasons against it), to back up the original RAW files first in a separate location if you don't already have a backup. You might need the RAW file later. If you embed the RAW file in the CR2, you end up with very large files (about double the size of the original file), which completely negates the filesize advantage of dng, which is without embedded raw about 10-25%. You will be able to extract the RAW files later if need arises though which might be convenient but absolutely not necessary.

Can I convert to DNG after I have edited all my original Raw files in Lightroom?

I'm asking because i've become convinced to use DNG's instead of NEF's and RW2's from my Nikon and Panasonic cameras. My main reason is future compatibility.
I have already edited all my NEF's & RW2's from the past 2 years in their native file format in Lightroom 4. Is it still ok to convert them to DNG now (even though they have been already edited (non-destructively of course)).
Thanks.
Also, why can't Windows Explorer show thumbnail previews of DNG's on my Windows 8.1 64bit Pc. I assume is has something to do with not having the DNG codec. However, on Adobe's website it says their DNG codec only works on Windows 7. Any ideas?
Thanks again.

Yes, you can convert your images to DNG at any time. But are you absolutely sure you want to do that? You won't be able to use any Canon or Nikon software to work on those DNG files if you ever find a need to do that. And I really wonder about the "future compatibility" issue. But the choice is yours, of course.
You will have to do a Google search for a DNG codec. It will have to be installed in order for you to see your DNG content in Windows Explorer. You worry about future compatibility, but you have to be concerned about compatibility now in order to use DNG files.

Converting to dng after the moment

I've just started to convert my 5D RAW files to DNG before importing into Aperture.
However, I have about 1500 images in Aperture which are .cr2 with metadata and adjustments applied. Is there a way to convert these to dng and preserve the changes without reimporting?
Ross

Use the export masters and export with the sidecar file option(under metadata in the export dialog). Just export into a folder and then use the Adobe convertor to convert these files to DNG. The DNG files will contain all the metadata such as keywords. Then import these DNGs into Aperture, Aperture will read the embedded metadata in the DNG and then I believe you can lift and stamp your adjustment settings from the original cr files onto the new DNGs and then if you want to remove the canon files you may.
As you know Aperture does not itself create DNGs from another raw format but once you import a DNG Aperture can export it as a master and embed any metadata into that DNG upon export. Remember that if you export a master that is not a DNG, if you choose to include metadata, use the sidecar option. An application such as Adobe Bridge will read the exported raw files sidecar to see its metadata.

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?

Converting files to dng after import

Hi. Brand-new Lightroom 5 user here. I don't remember the dialog box showing up to ask me at the time of import whether I wanted the pics imported as dng files or not. Now that they're imported, is there a way to tell if they are already dng? I also know how to convert them one at a time, but is there a way to just have them all converted at once? (There are a few hundred.) Also I'm being asked whether I want to only convert RAW files (I'm guessing that this is the case, but let me know if I'm wrong here). And if I want to delete originals after conversion (again, I think I do, but is there a compelling reason not to delete? Can you tell I'm not a professional photographer?)
Thanks much for your help.

See screen capture.

When you have one of the files selected the .dng extention will be displayed.
I also know how to convert them one at a time, but is there a way to just have them all converted at once? (There are a few hundred.)
Sellect the files in the grid view Library module and use the Library menu to select "convert to dng" see the screen capture.
Also I'm being asked whether I want to only convert RAW files (I'm guessing that this is the case, but let me know if I'm wrong here).
There is really little benefit in converting jpeg or tiff files to dng.
And if I want to delete originals after conversion (again, I think I do, but is there a compelling reason not to delete?
If you are using only Adobe products then you may never have use for the original raw files. However your camera manufacturers software and some other raw conversion software will not work with dng files. I am not a user of dng so my opinion is to always retain a copy of your raw files.
My main reason for shooting raw is to retain the original data for the benefit of utilizing further advancements in raw conversion software in the future, including software that does not support dng files.
Can you tell I'm not a professional photographer?)
No, as far as I am concerned there are many professionals and amateurs that may not know the answers to your questions.

Will edited Raw files retain the xmp edited information when converting to DNG format?

I have a bunch of old nikon and canon Raw files that was edited in Photoshop Camera Raw. The Raw files have corresponding xmp files. I want to convert these edited Raw files into DNG format. Using the Photoshop Camera Raw converter or using the free Adobe DNG Converter tool - will the edited information from the Raw files be automatically converted over to DNG? What would be the best method to convert an edited RAW file into a DNG file, and retain all the editing (xmp files)? Thanks for help!!!

Using either the dng converter or camera raw though PS and Bridge will convert your RAW files to dng and keep the edited info from your xmp files, which will be add into the dng format. If you have a lot of files to convert, it might be faster to use the dng converter. Next choice would be to select them all in Bridge, right click and select "Open in Camera Raw."

After editing a video clip in FCX that was shot in 60fps how do I convert that clip to 24fps for publishing?

There is only a limited amount of Compressor instruction available unless you purchase a subscription to something like Lynda.com or a tutorial from Ripple or Larry Jordan.
My advice to everyone who is interested in learning about Compressor is to read the first two chapters of the user manual – on basics and workflows. Those should provide enough of an understanding to cover the majority of things users need Compressor to accomplish. Of course there is plenty more for those who want to explore.
Here is a short write-up from Ken Stone on changing frame rates.

How can I safely convert CR2 files to DNG after Import from catalog

Images on my laptop from 2 photoshoots in the studio today were EXPORTED from laptop as catlog and imported to desktop as catalog.
I imported without moving the files anywhere since I was instructed to move that folder to its final resting place.
The 125 images were importred into LR4 but I see they are still CR2 files.
Is there a way to convert these guys to DNG inplace? or is it safe to re-import these. I don't want the side car gig.

Convert to DNG (Library Menu) - do not re-import.

Are adjustments retained after Convert to DNG?

I have a lot of NEF images to which I have already applied image adjustments. I would like to convert these to DNG.
1. Will my adjustments be carried forward to the DNG files?
2. If so, will they have exactly teh same affect when applied to the DNG files as to the NEF files - i.e. will the final adjusted images look exactly the same?
Thanks,
Charlie

1. Yes. The adjustments are stored inside the Lightroom database, not in the original files. Sometimes a copy of the adjustements will be stored in the file's metadata or in a xmp sidecar, but only when you turned that on. That file is not used by Lightroom but only by other Adobe programs when you directly access the images from them.
2. Yes, a dng is simply the RAW file stored in a different container. By converting to dng, you gain some degree of convenience in Adobe programs, but it really does not matter one bit if all you use is Lightroom or only call Photoshop from within Lightroom. Dng files are usually slightly more compact than original RAWs due to a slightly more efficient (and slightly slower) compression algorithm used in them. You do lose ALL compatibility with manufacturer sodtware (i.e. capture NX, Canon DPP, etc.). They do not read DNG files at all. So think deeply before you do this and my advise is that if you go the dng route is to backup the original RAW files somewhere before converting. You should be backing them up anyway.

When is my RAW file changed? Upon import? Upon viewing? Only after edit list started?

All:
I now have a "second copy" made in a separate hard drive when I import files from my camera cards. I want an untouched file for possible comparative "developing" or rendering in DxO or PhotoNinja. Might convert everything to DNG someday.
Asking LR to do this at the top of the Import pane is I assume, creates a copy *and* makes NO changes to the RAW data.
OTOH, Lightroom will offer me the image in Camera Raw to view, create, and interpret my edit/develop decisions. But I have been thinking about this and need to ask all of you: Is that CR2 file in my dated Lightroom database folders a changed file in any way from the RAW file while it was still on the card? The decision to hold edit data in sidecar files plays a part in this, right? External sidecar files means even after edits I can copy the CR2 file and use it in other [RAW]converter's software?
jonathan7007

Being a "non-destructive editor", Lightroom does not (cannot) change your CR2 files....with one exception, which is when/if you choose to edit the capture time of an image, in which case the changed date is written back into the file header's EXIF field. But apart from that, it is never ever changed.....all edits are stored primarily in the catalog's database, and optionally you can have them written into XMP sidecars. Having the XMP sidecar would allow you to open the raw file in another XMP-capable Adobe program, outside Lightroom, and see the edits applied. Not sure if other non-Adobe raw converters would be able to interpret all of that XMP info.
For non-proprietary raw files (e.g. DNG, Tiff), you can also choose to save the XMP data but in this case it would be written directly into the files header, not into sidecar files. The underlying image data is still, however, unchanged.

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.

Converting to DNG - is it safer?

I know this have probably been covered many times before, so please go easy on me... plus sorry if I'm talking crap!!!
I'm always worried about getting a corrupting database again... I've set LR to always back up the database on each launch... but this wouldn't prevent the loss of any work done after the backup say at the end of a long session the database corrupts - I've lost everything up until the last backup!!!
I liked the option to automatically write XML files, but its too much of a performance hit in LR v1.1
So I'm thinking about converting everything to DNG files as my understanding is that all changes are stored inside the header of the file, thus should the database corrupt, all is not loss (except for virtual copies, flags & ratings etc)... is this correct or am I talking crap????
Is there any disadvantages to converting to DNGs?
Any suggestions welcome...
Thanks,
Stewart

> "Where we tend to collide on issues, be it here or on other forums, is where you publish fluffy statements such as : DNG helps to make your data "future proof", or DNG is the only raw archival format. It's precisely that kind of fluff that I feel misleads and propogates "fear, uncertainty, and doubt"."
Name ANOTHER raw file format designed as an archival format! BUT ... use the characteristics used by archivists and librarians, and tell us what they are. The problem with this sort of discussion is that people make up their own definitions of archiving and the characteristics needed for it. But I have spent a lot of time reading academic and practical literature on this topic.
Archivists and librarians have a number of requirements, and the following page (for the US Library of Congress) is a good summary of them. They include disclosed specifications; wide adoption; self-documenting metadata, especially metadata formats that are also widely adopted; reduced or no external dependencies; no impact from patents; no encryption or other technical obstacles; etc.
http://www.digitalpreservation.gov/formats/sustain/sustain.shtml
People who believe that camera manufacturers' raw formats are suitable for archiving presumably use some other definition of their own. I believe they are typically talking about "back-up": being able to use the file in circumstances similar to today's circumstances. If that is all they want, that is fine - as long as they don't mislead people into believing that future workflows and tools will be sufficiently like today's that this will still work. Some of the tools we will be using in a decade haven't been thought of yet.
> "Even if DNG were more universally accepted, the format is designed to enable the blackboxing of data -- although another poster recently described it more like trolling through a tackle box than a black box ...".
If you simply mean "DNG files can contain DNGPrivateData that may not be documented by the creator" then please say so. That talk of "blackboxing of data" is just a FUD-phrase, and largely meaningless. Then you have to ponder that ALL of a NEF or CR2 isn't "documented by the creator". In other words, your criticism of DNGPrivateData is criticism of the whole of a NEF or CR2.
Now switch your attention to the parts of a DNG that ARE documented - by Adobe, rather than the creator, but so what? The parts that ARE openly specified are sufficient for high quality rendering, or previewing, or metadata-processing, etc. That is one of the key things that means it is false to say that DNG is "just another raw format" or "just another container". It is something that many people haven't understood - DNG is a self-contained raw file format, which can be handled by software products that don't have any built-in details of the camera model concerned. Name another raw file format with that characteristic!
This is one of the archival features of DNG. To write a new software product in future to handle the camera manufacturers' raw files from today's cameras, it will be necessary to build-in camera-model data for today's cameras. (But it won't for DNG). Now - where are they going to get that camera-model data from? Today, they get it by obtaining such a camera and testing it. In future ...? (My best guess is that they will either not bother for less popular cameras, or will extract the details from dcraw or similar for more popular cameras, or get it from DNG - which is where dcraw got some of its information, of course!)
> "For example, there is no assurance the work one invests into a Lightroom DNG -- e.g. spot remover, red eye remover, crop overlay, can be used by another application. That data, to the best of my knowledge, is locked away inside the file so that it is only available to Adobe applications. The portability of the value added by the user can only be realized within an Adobe workflow."
Your knowledge is wrong. Have you ever looked inside a DNG file to see what is there? (I suspect you haven't). Open one with Word - you will find the settings metadata in XMP format (nicely tabbed!) near the start of the file. It is exactly the same as the data in an XMP sidecar file. (It has tag 700 in the DNG file, in case you want to use a TIFF-tool to handle it).
The editing metadata, whether in an XMP sidecar or in a DNG file, is largely (not entirely) based on ACR or Lightroom sliders. But the editing metadata for any other raw converter is based on the controls of that raw converter - this isn't a problem specific to DNG or Adobe, but is industry-wide. Editing metadata tends to be editor-specific. But I'll bet that there is more editing metadata created every day based on ACR or Lightroom sliders than any other editing metadata.
I haven't seen a proposal for the commonality of editing metadata values; and I emphasise, this is not a fault of DNG, it applies to all editors and all raw file formats. But Peter Krogh recommends creating a full-sized JPEG (rendered using that editing metadata) and storing that in the DNG, either for general use or to identify the original rendering intentions. (It is trivial to put such a preview there and extract it later).
> "1. Nothing is future proof, only future resistant. That resistance depends on the current and future consensus -- which when it comes to DNG is still anything but clear."
One thing is clear - in this respect it is far better than any alternative! It is VITALLY important to examine alternatives using the same criteria, and NEF and CR2 don't stand up to the same scrutiny. (Too many people appear to use the argument "there are these problems with DNG, therefore we'll use these other formats", forgetting that they have all the same problems plus lots more!)
> "Before accusing others of spreading FUD, I think you need to put your own practices under the loupe."
I have published my analysis, and it is available for anyone to scrutinise. My pages give the information and evidence that analysis is based on. Where is your information, evidence, and analysis for us to scrutinise?
