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.

...if DNG is such a 'standard' and I was around when it was originally being developed and presented as a tool for circumventing the various manufacturer nuances, please tell me why, as a standard, Lightroom 5 reads these files just fine, and Aperture replys as "Unsupported Format." 

Because folks who call DNG an "industry standard" are wrong. I too was here at the inception of DNG. Adobe wanted to control imagery so Adobe created the DNG format and tried to push the world to adopt it. However Adobe is a software vendor not an image maker, and most of those  pesky camera companies including Nikon and Canon rightfully said something to Adobe to the effect of "are you nuts?"

 

The rationale Adobe made when pushing DNG was "use our DNG and everyone will always be on the same page, the world will be a better place" (coincidentally, tech improvements by camera makers would need to comply with Adobe's wants and needs). Obviously (per the OP's experience that started this thread) every DNG file is not the generic solution stated by Adobe at the inception of DNG. IMO Adobe's rationale was false from the beginning.

 

Another absurd claim Adobe made at the time was that only DNG would allow image files to read far into the future. As readers for NEF and CRW will somehow fail to exist because Adobe is not in control.

 

I have been an Adobe user since the early days and own more than a dozen current Adobe products but today the firm makes me a bit sick. CS6 is my last upgrade.

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.

    DNG is supported by Aperture. See list of file formats supported on page 29 of User Guide (Aperture 3.5).  Also while in Aperture, go to Help and search on 'dng' there you will find instructions on how to handle the format when importing.

     

    Hope this helps.

    hey geomon....

     

    I have been working with DNG files from a camera that will not import into Aperture although the same files import into Lightroom. 

     

    I believe that Aperture has some limitations to it's DNG support. 

     

    As I test, I took a jpeg file (created by the same camera and which would import into Aperture), opened it in Camera Raw, and then Saved it as a DNG. 

     

    Aperture would not import that file reporting an "Unsupported File Format."

    What camera are you using that Aperture won't support with its RAW files?  I can't think of a single one that doesn't work.

  • geomon Level 1 Level 1

    Rich - surprise, surprise!. Always something not quite the way it is documented with this paraticular app (rant). 

     

    I very intentionally keep my reliance on AP3 to straightforward DAM work with .cr2 as raw.  I was working with another fellow just recently who keeps dng as his archive format and AP3 took the images and metadata. 

     

    If a camera uses DNG, and that camera manufacturer supplies software, the software  will support DNG. However, the DNG implementation off the camera may be supported  only via that sofware and not generically. Since the camera manufacturer is not named, I cannot be more specific. Other software from other developers may not be aware of how that camera manufacturer implemented DNG. Since Adobe is the developer of the the DNG format, I would expect them to make sure they support virtually every combination of implementaiton of the standard.  It would seem Apple  provides only a partial solution. So, not much more to say except to revert back to Terrence Develin's suggestion.

    The D4s is a good example of a currently non-supported camera. It will be supported RSN, but not as of this writing.

    Well, I  meant cameras that have been out for more than a month or so.

    There's something to be said for those CCD sensor cameras.  What RAW format did Panny use for those?

  • Keith Barkley Level 5 Level 5

    The RAW format is irrelevant. Each camera needs to be supported, even if they all have the same RAW format. For example, Canon probably has a dozen cameras that use the 18MP APS-C sensor and raw format, but they all had to be supported individually.

    It's not irrelevant as the DNG file format is something of an industry standard developed by Adobe.  For example, Aperture could read the DNG files from my Pentax long before Aperture supported the camera itself.  Now for something like a Canon, which uses a proprietary RAW format (CRW I think), Aperture must support the camera before those RAW (CRW) files can be read.

  • Rich Hayhurst Level 1 Level 1

    I would prefer camera RAW as well, but the camera provider does not offer it, only offering DNG support.  My guess (a bit cynical I might add) is that Adobe is paying them for the "privlidge" of only offering DNG, that is not supported by Aperture.   And conversely, I would guess that Apple is not going to chase every iteration of DNG that Adobe creates.

  • Rich Hayhurst Level 1 Level 1

    The camera is attached to a drone (quadcopter, multirotor, etc), from dji.com.  No raw off the chip is offered.  The images are beautiful in DNG (Lightroom) but while the camera also does a jpeg conversion simultaneously, it's 2nd rate imho.   The manufacturer of this camera is not provided (that I can find) by dji.com.
