No Linear Adobe DNG support?

Reason I would like to see Linear DNG is for the sake of Sigma X3F RAWS. Since the X3F is a non-mosaic RAW DNG Linear would be just fine since Aperture doesn't seem to know how to handle non-mosaic RAWs or they don't want to. Simply converting X3F RAW to TIF isn't good enough to get the full benefits of RAW. Opening up DNG Linear within Aperture would be advantageous for Apple and for their users. If they can allow JPEGs within Aperture it would seem to me that opening up DNG Linear would be more than fine and would address a host of problems for Sigma users.

Actually it is true. DNG is NOT a standard. It is in fact a proprietary specification. Adobe has released SOME of the DNG spec to outside vendors, but there's no way to prove they've released the entire spec. It is their system and they control it.
For a file to work within the DNG format, enough of the information supplied by the camera manufacturer's SDK has to be DNG compliant. I've spoken with Apple engineers who explained that the DNG format is too limited to get a good decode unless the SDK offers enough corresponding good information. For instance, a certain camera may support parts 1, 2, 5, 7 and 9 of the spec, but not 3, 4, 6, and 8. While technically, you could open the DNG file under these circumstances, you couldn't get a good decode.
Apple simply decided not to let a poor decode creep into the system just so that they could say they supported a camera.
While I am sure that some of the limited RAW support we're seeing is indeed the result of miscues or miscalculations by Apple, I believe that the camera manufacturers share an equal portion of the blame.
We already know that Nikon for instance has a history of refusing to play well with others when it comes to their "as shot" data. While that's been resolved with some Nikon cameras, it is still an issue with others and a perfect illustration of why users should be putting heat on their camera manufacturer to get the RAW file format support they want.

  • Adobe DNG support ?

    Hi all,
    In Aperture documentation there is "support" mention about DNG files. I have Leica Digilux-2 camera which makes "Leica/Panasonic" RAW files. These RAW files are not in Aperture list, but I can convert them with Adobe DNG converter. But Aperture nod not open these DNG files ? Is there some other DNG format than Adobe DNG ? Or have I miss something. I really like to use RAW format also in my Leica.

  • Adobe DNG files not supported in Aperture 3.1.2?

    Those of you that follow this forum may have read my previous post - https://discussions.apple.com/message/15009745#15009745 - about RAW files from my old Windows machine whice look fine in iPhoto, but when I imported my iPhoto library into Aperture 3 they have this red haze over them like a flash coloured gel.
    As I said, the older files came from my old Windows machine, where they had been stored in Photoshop Elements, and in the past I had converted them from Canon's .CRW file format to Adobe's .DNG format. I've just checked in Aperture, and it is indeed only these which are washed out - all of the Canon .CRW files look fine, it's the Adobe .DNG files which are a mess. I'll hazard a guess that Aperture doesn't support the Adobe .DNG format I have and that is the issue, but why they are supported in iPhoto and no the professional app I can't imagine. A call to Apple tomorrow morning is in order to sort this one out I think unless any of this excellent forum's followers can offer help. Has anyone had a similar experience importing .DNG files into Aperture 3? I should add that they bad either form the original import from iPhoto, or directly importing into Aperture.
    Thanks James.

    Hi Bob, here's a quote from the link Stephen provided:
    "Adobe Camera RAW converted DNGs won’t work because the fine print of Apple’s DNG support shows that it only works with unconverted DNGs—and the new lensdata support of Adobe’s DNG specification generates converted DNGs. While, Adobe may disagree with me (and there is a good reason why they should), this is just the sort of moving-target that causes me to argue against converting to Adobe DNGs."
    As I said in the post this provides some useful background information, but I can't imagine that iPhoto uses a better DNG converter than Aperture (although perhaps older, so maybe that's why I can see the files okay in iPhto and not Aperture?). As for my OS, it's the latest version, I've done two software update checks this week so would for sure have run that when it came around, but I appreciate yours and others thinking on this problem of mine.

  • Aperture lack of DNG support unfortunate

    It's difficult to understand why Aperture does not offer support for Adobe DNG files. 
    DNG/RAW files are being used by some camera manufacturers that I work with, and they contain a wealth of metadata as well as the broadest range of image data, including "altitude", which is now very useful in my professional work.
    This lack of support has forced me to go back to Lightroom, and to reconsider that application as my primary media catalogue and editing application.

    A JPEG saved as a DNG isn't really a DNG file.
    It is true that Aperture doesn't have "comprehensive" DNG support. It doesn't support linear DNGs, and it doesn't support some of the newest DNG extensions that Adobe has added (lossy compressed DNGs, etc.). I don't know the exact version of the spec that Aperture supports.
    But do note that DNG is a lot of things. It's a fairly comprehensive spec that has many versions, with lots of different things. Aperture does support many DNG properties, but not all of them. If you want the latest, greatest, most comprehensive DNG support, then Adobe will have it, as it's their specification.
    I personally just use the RAW files that come out of camera - whether they be NEF, CRW, CR2, or DNG. I _never_ convert my camera RAW files into DNG, because that actually strips some data (in my case, focus point informatin from CR2 files that Aperture can display, is removed from the converstion to DNG). There are many long-winded discussions on the "value" that DNG provides, and I don't subscribe to them. It provides no legay-proofness today that's unavailable other places.

  • Using Sigma DP1 Raw X3F files via Adobe DNG Converter to Aperture 2.1.2

    I wish to use Aperture 2.1.2 with my Sigma DP1 raw ( X3F format) photos.
    I used the latest Adobe DNG converter 5.1.0.30 to successfully convert Sigma DP1 X3F to DNG format files. After importing the DNG files into an Aperture directory, they were not an acceptable file format, and thus I could not use them.
    Does this mean that Aperture is not reading the DNG file correctly or Adobe has got it wrong with their DNG conversion of the X3F file format ?
    Do I need to wait for an Aperture update to fix the problem of using the X3F file format ? Is there a solution around in using Aperture with Sigma X3F raw photos ?

    Aperture does not currently support Sigma X3F or linear DNG (only raw DNG), and Adobe's DNG Converter can only yield a linear DNG from an X3F. So your only choices right now are to use a different product such as Lightroom which does support X3F, or use the supplied Sigma Photo Pro software to generate 16 bit TIFFs which you can then import into Aperture. Because Sigma Photo Pro is unstable and slow on Macs, I've been effectively forced to use Lightroom. Lightroom is a capable product, but it lacks the elegance of Aperture, so I remain dimly hopeful that Apple will eventually support X3F, and somewhat more hopeful that it will at the very least eventually support linear DNG.

  • Adobe DNG Converter For Panasonic LX3?

    The recent Apple update still does not recognize Panasonic's LX3 camera. I believed I could still get a Raw image into Aperture by doing the following:
    Using Adobe DNG Converter, and looking at Aperture's requirement that the linear compression option be turned off. I converted the Raw format file to DNG and then tried to import it into Aperture. Aperture seems to "digest" the image, but then states the format is unsupported. Am I doing something wrong? Why doesn't this seem to work?

    I think the problem is, for the LX3, Adobe demands that Linear conversion be on for the LX3. Given Aperture doesn't support this... I think you may be at loggerheads.

  • How to save 12-bit RGGB RAW in 10-bit log Adobe DNG?

    I am implementing a vision project, and want to save disk space by converting the 12-bit linear raw files to 10-bit log Adobe DNG files.
    I went though the DNG document but could not find the formula or matrix to convert from 12-bit linear RAW to 10-bit log DNG.
    Can someone kindly offer these details ?
    Cheers!

    I'm glad you mention the issues with packing bytes.
    I had 12-bit RGGB raw saved as  a DNG, but the colors were off.
    The byte order in Adobe is different and seems to be undocumented.
    I had not problems with 8-bit RAW converted to DNG.
    https://dl.dropboxusercontent.com/u/9906333/12-bit.zip
    I have code that writes packed data, but it would be nice to access the way that DNG expects the packed data to be written.
    For 10-bit, I would be looking at 4 pixels in 5 bytes. I am unaware of any packing that would allow this, and if Adobe DNG actually supports this.
    At least with 12-bit, 3 pixels in 2-bytes, there seems to be support - however, the actual pixel order is unknown.
    I will go through the Linearization tables in the DNG spec now.

  • Leica M Monochrome DNG support

    It doesn't seem like Aperture supports this file format, can someone help as I seem to have exhausted every other option.

    Unfortunately Apple still does not support the Monochrom RAW/DNG file. Actually Apple does not support any non-Bayer sensor (Fuji Xtrans for example).
    The workaround suggested by leonieDF unfortunately does not work. The Adobe DNG converter generates dng files that are still not supported (regardless of "convert to linear image", "compression" options or any raw version chosen).
    Bruce's option works. Unfortunately the TIFF file generated is usually 3x the size of the DNG and does not seem to be as good to be manipulated (shadow detail for example). You can use Adobe Camera RAW but there are at least 2 other RAW converters (RPP and Photo Ninja) out there that now supports MM DNG's.
    There are a number of programs that now support the DNG for the Monochrom. Lightroom would be the obvious one since comes with the Camera. PhaseOne C1 also now supports the DNG.
    I understand that Apple is working on getting the MM files supported. It seems that it may require not only a RAW support update but also OS update. I would suggest to send a feedback to both Aperture team and Apple OS team. The more feedback, the more they will know we want support for this camera.
    What I have been doing so far is to shoot JPG+DNG and editing the JPG. Once support is released, I can just use the RAW as primary and the edits will then be done at RAW level (may need more adjutments though). Not ideal (far from) but I am not ready to move to Lightroom.
    Cheers

  • Can't open .CR2 files in PhotoShop CS5, Camera RAW or Adobe DNG Converter

    Firstly take note I shot these with a Canon EOS 450D (or Rebel XSi)...
    I see a lot of answers speaking about having the most up to date version of the Camera RAW Plug-in.
    I have a similar issue with my .CR2 files... I cannot open them in Camera RAW because it tells me that my camera model or make is not supported by the Plug-in, and so I was directed by other forums to just try converting the .CR2 files to .DNG. I already had the Adobe DNG Converter (version 6.5 I believe), so I tried this. It too told me that my files or camera make were not supported.
    However, I have always been able to successfully both open my .CR2 files AND convert them to .DNG. I had not updated anything on my camera nor on my Adobe programs and for some reason this last attempt to open RAW files failed me... I have no idea what change would have led to it. Luckily I shot in both RAW and Large JPG but I certainly don't want to rely on my JPGs of course... Any idea why this problem might have arisen now if it had always worked easily in the past?
    Thanks!

    Are these the same exact files you've opened before that you cannot now open?
    Or are they newly copied files (camera or CF card to computer)?
    Can you not open ANY Canon 450D files, even those you find online and download?
    What I'm getting at with these questions is to try to eliminate or suspect data corruption of the files on your disk.
    Exactly what versions of the various tools do you have, specifically (don't guess - go check)?

  • Adobe DNG Converter can't recognize any files

    Hi All!
    I'm new here and would very  much appreciate help.
    I am running a Mac OS X 10.04.11 and would  like to open .CR2 files (native file from my Canon 500D) in PS4      / Bridge  CS4. My problem is that although I have downloaded the Adobe DNG Converter and Camera Raw 5.1  update as described  here: http://www.adobe.com/support/downloads/detail.jsp?ftpID=4057,  the DNG Converter can't recognise any files at  all (they are greyed-out  when I go to select any folder). I also followed these steps from the aforementioned link (well at  least I hope I did it right, I found the reference to step 4 slightly  confusing):
    To install with Adobe Creative  Suite 4 or Photoshop CS4:
    Automated installation on Mac or Windows®:
    1. Select "Updates..." from the Help menu
    2. Follow the on-screen dialogs to download and  install the latest  available Camera Raw update  
    Manual installation on Mac:
    1. Exit Photoshop CS4 and Adobe Bridge.
    2. Open the Finder.   
    3. Navigate to the root of the local disk (not the user's home  folder).   
    4. Navigate to: (Please read directory carefully)
    Library/Application Support/Adobe/Plug-Ins/CS4/File Formats
    5. Move the existing plug-in to another location (for example, a new  folder on your desktop). Ensure you keep this version in case you need  to revert back.
    6. Copy the Camera Raw plug-in, Camera Raw, from the download  into the same folder as in Step 4.   
    7. Launch Photoshop CS4 or Adobe Bridge.   
    Is that version the right one for CS4?
    Only Finder and the Canon Software can preview my .CR2  files, Photoshop still gives the message: "Could   not complete  your request because Photoshop does not recognise this  type of file." and   Bridge only shows me a generic RAW thumbnail. This message also  appears in PS when I double-click on the  Camera-RAW.plugin. I also  restarted my computer,  but that didn't fix it.
    Can  anyone help me out please? I'd urgently need a solution.
    Thanks in advance!

    I now uninstalled the older 5.1 version and  instead installed the DNG Converter 6.3 separately and it works  perfectly.
    About the Camera Raw 5.6 update: I also downloaded the plug-in  (which I think should be the last version CS4 supports) and can now open  my .CR2 files in PS, Bridge previews them too. :-)
    Is it advisable to keep both, .CR2 as well as .DNG files? Why is it  that my .DNG files are lighter than the native .CR2?
    Thanks again!

  • Can't find any raw files to convert when I am using Adobe DNG converter

    Recently I purchased a new Olympus XZ-1 camera. I shoot exclusively RAW pictures (raw files for this camera are called .orf). Then when I tried to import these .orf files in the organizer of Phtoshop Element 8 it was imposible, nor then I could see those pictures in the organizer. By surfing on diffrent forums, I was able to figure out that Camera Raw included in Element 8, Camera Raw 5.5, is not supporting the .orf raw from Olympus and if I didn’t want to upgrade my Element 8 to Element 9 or 10, a simple alternative was to download Adobe DNG converter to convert all my .orf files into dng files, which could then imported by Element 8 and opened in Camera raw 5.5.
    I downloaded DNG converter version 6.6 and installed it in on my computer running on Windows 7. The problem is that once inside DNG converter, when selecting the folder where all my .orf files are (Select folder), I can't see any raw files to convert there! I tried to select a folder with NEF files instead (raw files from Nikon) and it is the same problem! Why can’t I see those files of mine I want to convert when I select the folder in DNG converter?
    I'm dying for help!
    Thanks a lot!

    When you are selecting the folder in the DNG converter, you only click on the folder.  You DON'T double click on the folder.  After you have set your options, and chosen the folder, you click on the Convert button.  It is only after you have clicked on Convert that you will see the list of files that are being converted.  You will also be able to see an indicator of the progress of the conversion.  It really does work.  Just to verify, the procedure I outlined is one that I did just prior to trying to write the instructions.  It really isn't rocket science.  Just choose the folder, only the folder, and click on the Convert button.
    You'll notice that the button prompts you to select the folder, it doesn't say anything about selecting a file.  You only select the folder that contains the files.  You will never see a list of files using this method.  If you only want to convert one or two images you can use the other method.  Leave the DNG converter closed, open the folder containing the DNG files in your operating system folder browsing utility, choose the file you want to convert, and drag it onto the icon for the DNG converter.  That is how you choose individual images.

Despite downloading and installing the latest version of Adobe DNG converter, I receive an error message saying that Photoshop CS4 can't open up/convert raw files (.CR2).

  • Problem with Adobe DNG in Aperture 2.1.4

    I've never had a problem with DNGs until now. I have Pentax DSLRs and can import their RAW format (PEFs), but my workflow involves converting PEFs to DNGs using Adobe RAW Converter, then importing the DNGs to my managed Library.
    Just got a Panasonic Lumix DMC-LX3 which has RAW format of RW2 which I understand is not supported by Aperture 2.1.4. However, given my workflow, I simply converted the RW2s to DNGs using ARC v.5.6. The problem is Aperture doesn't recognize the DNGs. This doesn't make sense as I would think the DNG coming out of ARC should be readable irrespective of what the original RAW file format was.
    Any ideas on what the problem is (short of upgrading to Aperture 3)? This seems like an Adobe DNG problem, not an LX3 file format issue.
    Thanks for any help anyone can provide.
    Steve

    The buttons are on the same line. I would like to upgrade to 2.2 and I'm sure that we will at some point, but it won't happen without some time dedicated to testing. I'd like to get this figured out with version 2.1. The strange part is that it just showed up after the portlet was enhanced. I looked at everthing changed and I can't figure out what could have caused it. Anyone have any idea what would cause 2 buttons in one TD tag not to both receive the onclick event?

  • Trouble with Adobe dng converter and 5d mark iii

    I have recently downloaded the dng converter 6.7 to convert my cr2 files from my 5d mark iii, however it keeps on telling me i have no files to convert, is there anything i can do about this? i am using elements 10

    Test with the new 7.1 DNG converter:
    Windows: http://www.adobe.com/support/downloads/detail.jsp?ftpID=5389
    Mac: http://www.adobe.com/support/downloads/detail.jsp?ftpID=5388
    See if that changes anything. If not, we'll want to take a look at one of your files to test.

  • I cannot convert my .cr2 files in Adobe DNG

    Hello,
    Can someone help me with my problem before I loose this client.
    I've recently started using the Canon 60D to shoot videos and take pictures. Since I've started using the 60D I was able to land a client who needs pictures taken for his clothing store. I understand that taking RAW pictures are better than JPEG so I am just now experiencing RAW. However I've come across a problem that I cannot find a solution to. I currently own Photoshop CS4 and I do not have the means right now to upgrade to CS5. Photoshop does not recognize my .cr2 files and I later downloaded Adobe DNG 6.4 to convert my files. DNG does not recognize my files, since then Ive removed it and downgraded  to DNG 6.3 and it still does not recognize my files.
    I've tried everything imaginable and nothing seems to work. I've tried dragging and dropping my pics into the Adobe DNG icon, moving my pics to my C drive, downloading Canon RAW codec which then turned my files into a unrecognizable data file and I had to reupload my pictures from the camera again. I do not have a CD-ROM for my camera because it is not mine, but someone elses who is letting me use it for business. I have to show this client the pictures by Tuesday and if I do not have this problem resolved by then I could loose this client and all of this hard work was for nothing. Please help, Thank you. 

    According to the readme file, the 60D was not supported in ACR 5.7 which was the last version created that is compatible with Photoshop CS4.  If you are not in a position to upgrade to Photoshop CS5 then download the latest DNG converter (currently version 6.4) and convert your raw images to DNG files.  Then make you will be able to open those with what you have.
