“Help, I Can’t Open These Raw Files!”: What To Do When New Cameras are Released

Published September 1, 2016

Every time a new camera is released, and usually, for a couple of months afterward, I get lots of calls and emails from customers asking why they can’t read the Raw files they just shot.

“They’re just CR2/NEF/ARW files that I should be able to open! Something is wrong with the camera you sent me.”

Rest assured; the camera is not broken. If you can see the files but can’t open, the camera is fine. I still haven’t figured out why yet, but every time a manufacturer releases a new camera, they keep the file extension the same but change how the raw data is interpreted. This means third parties like Adobe, PhaseOne, and Camera Bits (Photoshop/Lightroom, Capture One, and Photo Mechanic, respectively) have to reverse engineer those raw files for their software to be able to work with them. That process usually takes a week or so after initial release, but eventually, they issue software updates, and all is well.

Or Is It?

Software costs money, and some of us don’t like to buy a new version when the old version still works perfectly fine. The problem is most companies will stop update support for older versions of their software (I’m looking at you, Adobe). Are you running Lightroom 3, 4, or 5? You’ll probably be left behind when the new Canon 5D Mk IV comes out. You’re already unsupported for the Canon 1DX MK II, Canon 5DS and Canon 5DSR, Canon 80D, and Canon T6i and Canon T6s, or for the Nikon crowd, the Nikon D5, Nikon D500, Nikon D7200, and Nikon D5500. Here’s a full list of cameras and supported version numbers for Adobe products.


If you haven’t already jumped on the Creative Cloud bandwagon, and you want to hold on to your old versions of Photoshop and Lightroom (or Elements, if that’s your thing), there is still hope for you. You can download the latest version of the standalone, free Adobe DNG Converter for your Mac or PC:

DNG Converter for Apple Computers

DNG Converter for PC

DNG stands for “digital negative” and is an open raw image file format. It’s a generic version of CR2, NEF, ARW, etc. that can be read by a variety of software platforms without needing proprietary decoding. There are a handful of cameras out there that shoot straight to DNG, including Leica bodies and Pentax bodies. It would be a much easier photo editing world if more companies would adopt the DNG format, but alas, it is not so. There are also some caveats to converting to DNG, but that’s really beyond the scope of this article.

If you just want to get up and running with old Adobe software, this is the quickest and easiest way to do it. Get the DNG converter, convert your raw files to DNG, then open them in your old Lightroom. Voila!

If you’re on Capture One, everything I’ve just said won’t matter to you. You know what you’re doing, and you’re ahead of the curve. This isn’t a slight against Adobe users; there are just a lot more amateurs using Adobe products. Same goes for Photo Mechanic users. Just check for updates and you’re all set. If there’s no update yet, just wait a few more days.

There are a handful of stubborn Digital Photo Professional and Capture NX users out there that none of this applies to as well. Canon and Nikon give you updates all the time when their new stuff comes out, often before the cameras start shipping. And both apps are free! Googling “Canon Digital Photo Professional” or “Nikon Capture NX-D” will get you going pretty quickly. Since they’re proprietary pieces of software reading proprietary raw file formats, they’re going to give you the best raw conversion results (I guess that’s pretty subjective, but that’s also a discussion for another time).

Are you using GIMP, Affinity, or anything else? Sorry, I am no help to you. Best hit the forums or contact the developer.

Hopefully, all of this makes sense. The digital photo world is always changing and updating, and it’s easy to get left behind. With a little luck and some handy links, though, you can get a little more life out of what you’ve already got in computers and software.

I’m Joey. I love cameras, especially old film cameras, and I can’t remember the last day I didn’t take a photo. Digital cameras are great, and they keep me employed, but I also still like processing my own film. I’m stuck somewhere in the middle. I shoot every single day, no matter what.

    Capture in DNG format. If anything, buy a camera that does allows this, as in in fact all cameras should. If a camera doesn’t, it would actually be comparable to a camera in analogic times that did not allow to use standard sized film rolls from the likes of Fuji, Kodak, Agfa, whatever.
    What a bloody, stupid, commercial world we humans have created, in which usefulness and/or creativity allways comes second to financial profit of companies that consider themselves powerful enough to dictate the rules, and Canon is one of the best examples of these dirty policies.

    I’ve tried converting with the DNG converter per the above, and still no luck. Any other suggestions on how to convert or read my files other than Canon software? I’d had to enter a serial on my rental camera, and the software acts buggy anyway.

  • Paul Ringger

    For the Canon 5D Mark IV, the “Official” Adobe Answer is “Use Canon Digital Photo Professional 4.5.0+”. There’s no ETA yet on when the software update will be released.

  • DrJon

    No as Adobe have stopped updating ACR for earlier versions of Photoshop, only Photoshop CC gets updates now. Lightroom 6 (the non-CC version you can buy) still gets all the new camera updates, but not feature updates.

  • DrJon

    This depends on whether you keep the original Raw, plus what choices the DNG converter makes (the DNG spec has several different ways to do things and I’ve yet to see a list of which choices it makes).
    Note you can select to have the original Raw file saved in the DNG, but it will double the size (I’d just keep it separately personally).
    There are a few interesting comments in this thread:

  • Shawn A Krueger

    No love for Apple Aperture? ;^)

  • Badboy35

    Because they lack features so aren’t complete solutions. They are good at what they do however.

  • Joey Miller

    Yes! Thanks for pointing that out.

  • Joey Miller

    That’s basically the same thing as getting the DNG Converter. Adobe lists them together on the link I provided.

    And then the support for new cameras in the system software…
    I am on Apple and Apple forces you (also in this way) to use their latest system software, even if it is called El C(r)apitan.
    Without it you cannot see the thumbnails of your new camera neither convert RAWs in Photos.
    Many thirdparty programs rely on Apples support; for instance Media Pro1.

    The most recent version of Canon Digital Photo Professional doesn’t even support CR2 files from their earlier models (i.e. EOS 5D Mk I) – this is the reverse of the situation described above, but just as important.

    Why do you call DPP/CaptureNEX users stubborn? 🙂 One would think the Canon raw converter would give the best results since it is made by Canon for Canon cameras?

  • Tim Dunnell

    Even though you can save DNG format with the Pentax K1, it is not compatible with Lightroom 4, but it can be read with Photoshop CS5. So even DNG versions are not the same. Had to upgrade to LR6…

  • Till Ulen

    Joey, what are the possible downsides of converting to DNG?

  • Shane Castle

    DxO Optics Pro has been very good about publishing updates to existing versions to cover new cameras rather than forcing users to upgrade in order to support their latest gear.

  • Cesjr86

    For converting the raw files can’t you just download the newest version of ACR and as long as Adobe has created a fix for those files it will work. I am not completely positive of this because first I never own a camera when it is first released (I am poor lol). Also, I currently have Adobe CC.
