What is a DNG file?

Good Evening, Could you please tell me what DNG files are? I know when you import to LR it gives you the option to import as DNG,or Copy, Move or Add. It seems as if I import as DNG I can't use it on other editing programs.
Thank you,
Kenny

So when I import should I import to DNG, or what? Then do I save them as a Tiff?
Hi Kenny,
If you know you are going to convert to DNG, you might as well do it upon import. No need to save to tiff (tiff is mostly for externally edited photos).
As DJ said - there are tons of threads about it already that can help you decide.. - in this forum and elsewhere.
My advice? if you don't know why you're converting to DNG, then don't. - it can be done at any time in the future (without any sort of penalty whatsoever) if you decide to.

  • What causes RAW DNG files not to open in PSE 7?

    I installed converter 5.5 but I still cannot get PSE to open DNG file.  The error message is "could not complete the request . . file not a valid photoshop document".  The error message is the same as I got before I installed 5.5 but the converter symbol is adjacent to the DNG photo file so perhaps that install worked if it didn't work before.  I have no problem in opening or re-opening the file in the raw processing software.  The manual says I should be able it open processed files (DNG) in PSE editor.  Where did I go wrong?
    Thank you

    You are correct in that ACR 6.4 or later is required to read the Nikon D5100 raw files.
    The last ACR that PSE 7 supports is ACR 5.5.
    That is what I was afraid of.

    Adobe does provide the free DNG converter for those who wish to continue to use old versions when they upgrade their camera. Some people actually prefer to do the conversion even if the camera is supported by the version of PSE that they have.
    Unfortunately the Adobe DNG throws a message to the effect of "File was unable to be written" on every file, without any further explanation.

  • What kind of DNG file for DNG profile editor ?

    Can somebody help me??? I have a problem to use DNG profile:
    I am user of Fujifilm S5Pro, which has RAF file (=raw). The ACR (start from version 3...) and DNG understand my RAF files very well. But DNG profile editor dose not want to open it, even if Adobe DNG Converter 4.5 converts it to DNG file. My workflow is:
    Launch Adobe DNG Converter.exe, => convert RAF to DNG (tryed different settings);
    Launch DNG profile editor, => trying to open DNG file => have error???
    May be I'm doing in a wrong way? Please advise me.

    I tried to do the same on other PC with Vista (fully English). Also update DNG converter up to 4.6. And no success... :-(.
    Every time I have the same error: "DNG Profile Editor could not open the selected image. Note that the selected image must be a valid DNG color image."
    I could not understand... where is a bug.
    Moreover, I took NEF from Nikon D80 and CR2 from Canon 20D and converted them to DNGs by converter 4.6. DNG Profile Editor did not want to open them on both Windows Vista and XP, and made the same error.
    Do I really do wrong things? I'm completely lost
    Thanks in advance,

  • Converted Library to DNG now what about those other files?

    I've just taken the plunge and converted all my CR2 images to DNG, replacing the originals.
    However, I still have all the JPEG sidecar files left over. Can I safely delete these, or are they required by the DNG?
    Also, I was previously using the option to write to XMP sidecar files. With DNG is there any real need to keep doing this?
    Thanks

    Converting RAW files to DNG does not replace the original file. Rather it places all the data from that file inside the DNG in a standard published format. It can also contain a full copy of the file in its original format if you select that option (although this is really a waste of space). Think of DNG's as a box with a standardised filing system into which you file your data previously filed in a way only understandable by Canon, Nikon or whichever company designed the format. DNG's have a filing system that allows anyone to now read that data instead of just a few people "in the know".
    The DNG files will allow you to write what was formally contained in the sidecar files directly into the headers of the DNG file. If you had  automatically write all changes into xmp selected in catalog settings, then this will continue with DNG files but now write the data into the file header rather than as a  sidecar file. If you wrote the information yourself (by selecting write metadata to file from the metadata tab), rather than doing it automatically, then you can continue to do so. If you don't select this changes are stored only in the LR catalog and not in the file itself. The advantage of writing data into the file header (or as a sidcar file) is that other applications such as Bridge can read this data and if you import the DNG into a different LR catalog you can read the changes into that catalog, by selecting read metadata from file. The disadvantages include a small performance hit particularly on less powerful systems, you can still write the data to file manually in this case.
    As far as jpg files go, if these have been imported as separate files and you still want to keep them as separate files then don't delete them. To ensure any changes you make in LR are written into the header files then select this option for jpgs, Tiffs and PSD files in catalog settings on the same screen as where you set the options for xmp data for RAW files.
    Jpg files are not required by DNG's that contain a RAW file. A jpg preview file is embedded inside the RAW file and this will be also in the DNG file and used by applications not capable of decoding RAW data.

  • DNG files are importing into premiere pro cc with heavy pink tint what to do?

    I have tryed  many things to remove the pink to no avail, out side of importing through After Effects cc. What else Ican i try? Is there  a fiix in the works?

    This happens with certain video DNG files from particular cameras. Search here for dng import problems and you'll find threads about it ... including a recent one where someone found a look or LUT that could be applied to make the footage usable apparently.

  • I write both JPG and DNG files in the camera.   Camera is a Leica Monochrom.   Photo, unlike iPhoto, seems to ignore DNG files and only imports JPG files.   What am I missing here?

    I write both JPG and DNG files in the camera.   Camera is a Leica Monochrom.   Photo, unlike iPhoto, seems to ignore DNG files and only imports JPG files when both are present on the SD card.  JPGs are used for quick proofing on an iPad.    DNG RAW files are edited on a Mac Pro (2013).    Other than deleting the JPGs before importing images from the SD card,  is there any way to force Photo to select and import only the DNG images?

    Thanks Larry,
    I did see the J stacked in the lower left of the thumbnails but couldn't figure out how to get to whatever is below it.   How do you select R?  
    I use an iPad to do quick proofs of my images.   A JPG is good enough for a proof ( dust on the lens,  composition, blown out image, etc. ).   The iPad is JPG friendly and can load the images quickly.    Serious editing takes place on my Mac Pro with the DNG files.   I use the same workflow with the the Leica M 240.   iPhoto has been a quick and easy importer to the Mac capturing all of the metadata in the EXIF sidecar file ( location, date, time,  camera settings, lens type).  A quick scan in iPhoto for the "keepers" let's me export those worth editing to Lightroom/Bridge/Photoshop.  I typically shoot 50 images from three locations in a normal day.  If I'm lucky I'll get 1 worth real work to add to the portfolio.  

  • What is best web gallery to post DNG files and have invited users comment on the image(s)?

    I like Smugmug but it doesn't support DNG.  Picassa is okay for viewing DNG files but I don't see a comment capability.  :-( 
    I need to have a site where images are accessed by invited guests only and can be configured so that guests can comment on the image.
    Thank you for your suggestions.
    BA.

    You'll have to do a lot of searching because I don't believe there are any sites that will host DNG files. You'll have to export JPEG copies and post those for comments.
    The reason DNG files aren't hosted is because they are not image files in the traditional sense. They are still considerably larger than JPEG files, and need a raw converter to be displayed. That type of technology isn't part of web hosting software. To post on the web small files are required in a traditional image file format, most commonly accepted is JPEG.

  • 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?

  • Unable to see DNG files in Photoshop CS2

    Hi:
    I am using Photoshop CS2 in Windows XP Pro and have *.CR2 pictures taken with Canon EOS 40D.
    I downloaded Camera_Raw_3.7.zip and extracted Camera Raw.8bi to C:\Program Files\Common Files\Adobe\Plug-Ins\CS2\File Formats
    I downloaded Adobe DNG Converter ver. 4.3.1 and converted the Canon CR2 files to DNG files.
    I can see the pictures in Adobe Bridge CS2 1.0.4.6 fine.
    However, when I open Adobe Photoshop CS2 and try File/open, the drop down does not show any selection for DNG files. If I try to physically drag a file into Photoshop, I get the message that the extension is not supported.
    Upon opening Help/About Plug-In, I do not see Camera raw anywhere in the long list.
    What do I need to do to bring DNG files into Photoshop?
    Thanks.

    If you don't see Camera Raw in the list it usually means that it is not in the correct folder or the it might be damaged.
    It looks like you listed the correct folder at C:\Program Files\Common Files\Adobe\Plug-Ins\CS2\File Formats
    When you navigate to that folder do you see Camera Raw.8bi listed? It might only say Camera Raw, depending on how you have Windows set up.
    Did you restart Photoshop after putting the filter into the File Formats folder?

  • Can't open dng file in Photoshop cs5 from Lightroom 5.6

    Hello, I've searched around and can't find the answer to my question.
    Technical details:
    OS X v10.8.5
    Photoshop CS5 (ver12.1) Camera Raw ver 6.7.1.340
    Lightroom ver 5.6 (Camera Raw ver8.6)
    Camera: Nikon D600
    Minimum camera raw version to support D600 Raw is ver 7.3  and Lightroom ver 4.3
    I know that my version of PS doesn't support my Nikon D600 raw files so I've used the Adobe DNG converter and converted a raw file so I can process in PS. I can open the DNG file directly in PS and get the ACR screen to perform my edits. However, what I really want to do is open the DNG file in PS from LR.
    While in LR, if I select Edit in -> Adobe Photoshop CS5, I get the notification from LR that "This version of Lightroom may require the Photoshop Camera raw plug-in version 8.6 for full compatibility". I would have expected that regardless of whether I opened the (same) dng file from PS or LR (and edit in PS), that once in PS. the ACR screen in PS would be presented. Can anyone explain to me why this is the case and if this is normal or expected behaviour? Thanks
    Also:
    Adobe DNG converter preferences = Use Camera Raw 6.6 and later
    Lightroom preferences = File Handling -> Use Camera Raw 6.6 and later
    Thank you in advance,
    Mark

    As Station_two mentioned, you're using a version of LR that is not compatible with the older version of PS CS5. I don't know it LR has the ability to save DNGs to work in older versions of PS. If not, you will need a DNG converter to save them to the version of Camera Raw that PS CS5 can handle or upgrade PS.

  • Importing, copyping raw files as DNG files - copy to location choice, and more ???

    First:
    When I copy raw files as DNG files, the right hand pane shows where the copies will be placed.  (I use Windows 7) I do not have much of a choice, and cannot set a default.  The default choice is "My Pictures" on the C: drive.  I have an Solid State Drive, SSD, and do NOT store my photos on that small, 256Gb drive.  I store my images on an internal hard drive. 
    All i want to do is set the default "Copy To" location to where I store my images.  I would like to copy them to the original folder, in a separate folder (for example, LR DNG).  Instead, I have to open the SSD, find the files, and copy them to my preferred location.  This is very irritating.
    Second:
    Worst, it appears that the Copy function puts the copied images into multiple folders.  I had 11 images from raw files that were put into three separate folders.  That seems quite silly to me.  It causes me to do more work opening the folders and copying them to the root folder.  That is very irritating.   What is going on here?
    can these two issues be resolved? Thanks, in advance.

    My apologies.  I thought it would open the selected folder and reveal the images to be converted.  That would be the most obvious thing to do, but it does not behave that way.  I made a couple folders with test images, CR2 and RW2, and the converter converted them. 
    Again, the navigation was funky, inconvenient, but it works.  i complain because we pay a lot of money to use Adobe products, they have huge resources, and  they seem to release products that have obvious flaws, especially navigation.  Maybe they just hate Microsoft.  Sorry for the rant.
    Thanks for getting me to use DNG converter. 

  • 10.4.9 problem on DNG files and cd open/close tray

    After the new OS release, the file preview of my Leica M8 DNG files are no more visible. I need to open them but even setting "show icon preview" in the folder prefernces i get no result. Apple Preview also doesn't open the file anymore.
    In addition, to open the CD tray, now it requires to push the botton for at least double the time.
    Waiting for the fixies to this annoying problems.....
    .oesse.

    I updated to Tiger 10.4.9 the other day on my MacPro and today found that the Eject key wouldn't open the CD tray. When I realized that I had just experienced the same problem on a G5 at work a light went off in my head. Now reading this posting, I see that it is not "broken" but that the behavior of the key has changed.
    Since the behavior of the key has always been to just hit it, not hold it down, to open and close the tray, I don't see any good reason to change it. No other key on the keyboard requires one hold it down. It's counter-intuitive. I had already filed a ticket with my company's Mac tech support service to say my CD drive was malfunctioning and may need replacement. I had been able to open the door with a paper clip in the tiny hole and then insert and play a disk, but had not been able to make the tray operate normally. All of this because the behavior of the key has changed. I'd be willing to bet that people will be buying and replacing drives because they aren't aware. Certainly there will be a lot of money and time spent registering and responding to tech support calls on this silly issue. What a waste.
    I hadn't realized that the work computer had been updated to 10.4.9, and will still need to check this out, but I assume that is the case. I have to admit I didn't read the ReadMe file for the update I did at home because I was rushed and decided to forego that. Perhaps it speaks of this change. Does anyone know? Certainly if it does not, it should. I for one think Apple was a little knee-jerk on this one. Those who whine about a tray opening when they slip up and hit the wrong key should just be told to grow up.

  • Import is not working for DNG files

    I have imported couple hundreds DNG files from Lightroom into Aperture and instead of full file I've got message that they are unsupported files with very small pixel size like 350x171. The file size in metadata is real size but in preview I've got a message about ansupported file format!?

    There are quite a few different settings that you can choose from when converting a RAW file to a DNG. Without knowing what settings you set up in LightRoom there's no way to tell why your images aren't importing properly.
    Roughly speaking, a linear DNG is one where the first part of the RAW conversion process (called debayerising or demosaicing) has already been done by Adobe.

  • After upgrading to mountain lion aperture 3.3 no longer recognizes DNG files.  Is this going to get fixed?

    After upgrading to aperture 3.3 on mountain lion aperture no longer recognizes DNG files. 
    I have many DNG files already in my library.  Aperture shows the thumbnail and will briefly flash what I think is the preview of the file but quickly changes to a gray triangle saying "unsupported image format".  After which the thumbnail is replaced with an all black thumbnail.
    Needless to say this is extremely disconcerting.  I am concerned that aperture is not only refusing to display the existing DNG files but is also simultaneously corrupting the library and destroying my existing images.
    fwiw, these DNG files were generated with a leica.
    I have not attempted to import DNG images into my aperture library but I assume that would not go well.

    Susan,
    if it is the native raw format, that no longer is recognized, then try, if registering the CoreTypes.bundle with the OS again will help. This will tell MacOS which raw format types (and other media types) are supported.
    Open a Terminal window and paste following line into the window, hit return. This is one very long line:
    /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchSe rvices.framework/Versions/A/Support/lsregister -R /System/Library/CoreServices/CoreTypes.bundle/Contents/Library
    Regards
    Léonie
    P.S: Some browsers cause a blank to be inserted between /Frameworks/LaunchSe rvices.framework/Versions
    But it is "LaunchServices.framework", without blank. All in one line - the only blanks are needed between "lsregister" and "-R" and after "-R" .

  • Can you automatically embed Exif data in DNG files LR4

    For years I have been using Bridge and ACR for my raw workflow. I use only DNG files and have the database turned off so the EXIF data is embedded right into the original DNG file. This means my files are 100% portable without and sidecar.
    Can I work with lightroom 4 without having a database? OR can I assure that each DNG file has all it's setting automatically embedded as it does in Bridge?
    Thanks,
    Tom

    In the catalog settings, metadata tab, there is an option to automatically write to XMP.  That should do what you want.  Since there is no sidecar file with the DNG file exif data will be written to the file.
