Canon RAW files or DNG

Is it safe to assume that the .CR2 Canon RAW format will be around for a while or should I look at converting to DNG format? If the latter, I wonder when Aperture will be able to read DNG files?
Is there a way of converting all my .CR2 files that currently reside in my Aperture library to DNG format?
Many thanks

CR2 Canon RAW is a safe format. Millions of pix exist on it and it is unlikely to be dropped from support by major apps witnout upgrade conversion being made available.
Vendors like Nikon and Canon have been supporting their products for many more decades than Adobe has existed.
Camera vendors keep RAW image info proprietary and constantly evolving for improved image quality. DNG is Adobe's attempt at genericizing RAW capture but who says Adobe's conversion is in any way preferable? Each camera is somewhat different, but in general Aperture does a better job than Adobe ACR (the underlying converter for DNG), and often the individual camera vendors' RAW converters are better still.
DNG is only really useful for folks with brand new camera releases supported by Adobe but as yet unsupported by Aperture, and even then only if for some reason the camera vendor's free RAW converter is lame.
If the latter, I wonder when Aperture will be able to read DNG files?
Aperture reads DNG now.
Is there a way of converting all my .CR2 files that currently reside in my Aperture library to DNG format?
Sure, using Adobe Camera RAW (ACR), a subset of Photoshop. But unless ACR does a better job on your camera's files than both Canon and Aperture, which is highly unlikely, doing so IMO would at best be a waste of time, at worst lead to lowered image quality.
Edit:
The quality of RAW conversion in addition to being specific to each DSLR also is a matter of opinion subject to individual brain/eyeball evaluation.

  • I can't convert .cr2 canon raw files with DNG converter.

    I have a Canon 1000D, and im trying to open RAW files to edit in cs4. Everytime i open it, photoshop says that it doesnt recognise this type of file, but i open my friends RAW file (450D) and it can read it. I have also downloaded DNG converter, and it comes up with this message (first image) but my folder has .cr2 files......im really lost
    I have also asked for help on the photoshop forum, but they referred me here...
    Thanks

    That file is only 2.7 megabytes.  Raw files are usually larger.  That likely means it's truncated (cut off prematurely).
    You haven't selected one of the modes called sRAW (Small Raw) have you?

  • Converting Canon .CR2 files to .dng

    I have what appears to be the latest version of the Adobe DNG Converter (8.6.0.254); but when I direct it to a folder containing .CR2 files from my Canon PowerShot G7X camera, it tells me "No items match your search" and does no conversion. How can I convert this type of RAW file to .DNG?

    I don't understand your question. Here is what I do in the Digital Negative Converter:
    - Step 1 is "Select the images to convert"; I click on "Select folder" and navigate to the folder containing a .CR2 file
    - in that window, I see "No items match your search." even though it contains a .CR2 file from my Canon camera. Whether I then click on Select or Cancel makes no difference, since the program does not recognize any files.
    - If despite that, I click on Convert, I receive an error message "The source folder does not contain any supported camera raw files."
    In other words, .CR2 raw files are not being recognized by the latest released production version of the converter.

  • How do I open .CR2 Canon Raw Files in PS Elements 8 for iMac

    When I open a .CR2 Canon Raw File (Canon T3i camera) in PSE 8 for iMac, I get all greys - no color.  It is showing as color as a .CR2 on my desktop - when I bring it into PSE, it is grey.  I chose first 16 bit, then 8 bit.  Same result.  What am I doing wrong?  Thanks.  George

    Thank you Barbara for pointing this out. Since I'm new to forum stuff so missed the catch here. Got exactly same information as you posted. Got to know that ACR 6.2 doesn't support T3i files. It's ACR 6.4 which supports them but is incompatible with PSE8 ( http://kb2.adobe.com/cps/407/kb407111.html ).
    So the solution seems to be either upgrade to a newer version of Elements or download the free DNG Converter ( http://www.adobe.com/products/photoshop/extend.displayTab2.html ) and convert the raw files to DNG.
    Thanks again for correcting me here

  • Trouble converting Canon Raw images to DNG

    Hello!
    I have been using the Adobe DNG converter for a while without any trouble to convert my .CR2 (Canon Raw) files, but today all I'm getting when opening the program is this:
    So obviously I can't click on any of the buttons. I had the 8.7.1 version, so I downloaded the 8.7 version and the problem persists. I'm using a PC with Windows 7 if that helps. So far I've tried restarting my computer, uninstalling and re-installing the program (both versions), trying it with Photoshop opened/closed. Nothing works
    Do you have any idea what I could do to fix this? Or is there an alternative that I could use to convert .CR2 files to .DNG?
    Thank you!

    Here is another thread indicating the same problem, and a possible solution:

  • Options for Canon RAW files?

    I have a PowerPC at the office running 10.5.8. I am a graphic designer & photographer. Previously I was able to use iPhoto with my older DSLR to import Canon RAW files. I've upgraded to a Canon 60D and iPhoto no longer reads these new Canon CR2 files. As you know, CS4 is the latest version of the creative suite I can use on this Mac, and Photoshop CS4 doesn't open these RAW files either.
    I checked out Adobe DNG converter but it won't run on this system.
    Are there any options or is it just time to upgrade to a new Mac?

    I don't currently have the install disc with me, but I can try that later when I remember to bring it with me.
    I went to the Canon site to download a driver and it either is not available for my OS, or says I don't need it.
    I want to do all of the above (import from camera/SD Card, open, convert/modify) in a seamless workflow. I use Lightroom 4 at home which I love but only have access to iPhoto at work.
    Thanks for the help!

  • Canon RAW files

    Is PSE 12 compatible with Canon RAW files? I have just bought a Canon 5d Mk III and PSE 9 doesn't recognise the RAW files. I need to be sure I can convert my RAW files in PSE 12 before I upgrade. I also had a similar problem with PSE 9 crashing every second time I opened it and when I tried to back up the catalogue. Took the advice about creating a new catalogue and it seems to have fixed the problem.Now I have to work out how to back up the old file.....

    While Photoshop Elements works with Raw files, each new camera requires updates to the Camera Raw plug-in. To work with the Canon 5d Mk III you need Camera Raw version 6.7/7.1 (http://helpx.adobe.com/creative-suite/kb/camera-raw-plug-supported-cameras.html).
    Not all versions of Photoshop Elements will work with all versions of the Camera Raw plug-in. To use the Camera Version 6.7 you need Photoshop Elements 10. To work with Camera Raw 7.1, you need Photoshop Elements 11 (http://helpx.adobe.com/x-productkb/global/camera-raw-compatible-applications.html).
    So Photoshop Elements 12 will be able to work with this camera straight out of the box.
    To work with this camera in Photoshop Elements 9, you would have to convert your raw files to DNG with the free DNG Converter.

  • 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.

  • Can't open Canon RAW files in LR1.3, Photoshop, Bridge

    Hi.
    I'm having a problem with some Canon RAW image files a second photographer sent me. He sent about 800 files and I'm only able to import into LR (1.3) about 15% of the files. The remainder will not import. Upon import, LR says something to this effect: "files appear to be unsupported or damaged." I tried them on both of my macs (my G5 and laptop) and had the same thing happened. Photoshop says: "Could not complete your request because Photoshop does not recognize this type of file."
    They show with this icon: file:///Users/marthafitzsimon/Desktop/Picture%203.png
    When I do the "get info" on these files, under "General:" it says, e.g., that a file is a 10.8MB file. Under the "More info:" box, it says the dimensions are 0x0 (that's weird because when I look at this for other good files there are numbers for the dimensions).
    This is a picture of the "get info" window:
    file:///Users/marthafitzsimon/Desktop/Picture%201.png
    I have tried to open these files in LR, Photoshop, Bridge and Preview and nothing will open these.
    The files are locked so I unlocked one, but that made no difference whatsoever.
    I noticed one thing about the naming convention on the files,but I don't think this matters. My own Canon RAW files always have the .CR2 extension. All of his files have the .cr2 extension. Mine are all uppercase and his are lowercase. However, I don't think this could matter because the files I was able to download of his all had the .cr2 extension, just like the ones I couldn't download.
    (PS: Just in case you saw my earlier posting, this problem has nothing to do with that. This is another second photographer's files that I'm having problems with. Jonathon LeFaive solved that other problem for me.)
    Thank you for any help you can provide! Martha

    LR 3 is a complete new build so it will not overwrite the earlier version of LR 1.3 or its catalog or other settings.
    The install procedure will recognize your LR 1.3 catalog and ask if you wish to create/ convert to a LR 3 catalog. This procedure will not overwrite your 1.3 catalog but will create a LR 3 compatable copy.
    Download the trial which is good for 30 days before you will need to pay the upgrade price of $99 if you decide to keep. The trial is the full package and you will not be restricted in any way.
    The new features are a substantial upgrade with significant improvement in the conversion output of your raw files.
    Full details are provided in the "read me file" included with the download which should be read carefully before you install. The decision should be a no brainer.

  • Just upgraded to 10.8.4 and now can't open canon raw files in photoshop cs5 with camera raw plug in 6.7

    i've just upgraded to os 10.8.4 and now i can't open canon raw files in photoshop cs5 with camera raw plug in 6.7 which worked perfectly prior to the upgrade....anyone else encountered this issue?

    Adobe's software is a mess in terms of the fact that it's sprayed all over the place and may not survive an OS upgrade.  Try reinstalling Photoshop CS5.

  • Aperture 3.1 can't find/see my Canon RAW files when importing

    Aperture 3.1 cannot see my CANON RAW files when doing import!!!
    Do I really have to re-reference each image in the library if I have moved the library to a different volume? Images are not moved to the library, only referenced.

    You don't want to re-import files if you move the library. You just need to reconnect the masters.
    If you moved the whole thing over at once it should be easy; if you monkeyed with the folder names you could have a lot of work on your hands.

    What camera generated your Canon raw files.
    A lot more information about your hardware and software is needed.
    BOILERPLATE TEXT:
    If you give complete and detailed information about your setup and the issue at hand,
    such as your platform (Mac or Win),
    exact versions of your OS, of Photoshop (not just "CC", but something like CC2014.v.2.2) and of Bridge,
    your settings in Photoshop > Preference > Performance
    the type of file you were working on,
    machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
    what troubleshooting steps you have taken so far,
    what error message(s) you receive,
    if having issues opening raw files also the exact camera make and model that generated them,
    if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
    a screen shot of your settings or of the image could be very helpful too,
    etc.,

  • When i open my Canon RAW-files with preview or transfer them to another program using preview they change to color despite the fact that they where all shot in B/W... How to change this?

    When i open my Canon RAW-files with preview or transfer them to another program using preview they change to color despite the fact that they where all shot in B/W... How to change this?

    I shoot only RAW - no JPEG-files except those visualizing the files on my memorycard or computer. I think i have to refine my question;
    1. I know there is possible to make B/W HDR-images.
    2. I know the best HDR images are based on RAW-files.
    3. When i transfer the images in question to a HDR software they change, so when i view them in the software (either Preview or the HDR software) they are suddenly viewed (and processed) in color.
    4. This never happend on my PC so i know it has to do  with either Finder or Preview.
    5. Do i have to make all my B/W HDR-images on the PC or is it a way for me to change how Finder/Preview show/alter my images?

  • Unable to covert raw files to dng?

    using photo cs 3 ,unable to convert raw files to dng?

    Make sure you have the latest version of ACR for CS3 installed. I seem to remember it was something like ACR 4.6.  Check and see if it can save DGN conversions. I don't use DNG format for its not as well supported as manufactures raw formats.
    You can always download the latest DNG converter or a version 4 DNG converter http://www.adobe.com/support/downloads/product.jsp?product=106&platform=Windows
