    Default Problem with RAW import to Nebulosity



    Hello folks,

    I am having a problem getting RAW images into Nebulosity. I am using a new Mac with Image Capture to get them into the computer as RAW files. They seem to import as RAW files, though I can't view them. I just see a blank white box in place of the image. When I try to preview them in Nebulosity, I get an error message telling me it is "not a valid Canon RAW file - unexpected byte order."

    Any ideas as to how to proceed would be much appreciated. I've been stuck on this for hours.

    What version of OS X are you running and is it fully updated? Apple releases RAW compatibility updates occasionally as new cameras come on the market.

    Which camera is it?

    Hi Alan,

    It's an older Canon 570IS. And I'm running the latest updated OS X 10.7.3.

    Though I can't view the RAW files on the Mac, when I right click and select "get info", it does identify them as RAW files. So if they have been imported to the Mac as RAW files, I wonder why Nebulosity won't let them load into the program?

    Alan,

    And I forgot to mention that I get the same error message even if I try to load the RAW files into Nebulosity directly from the SD card using the built in card reader on the Mac.

    Dean from what I can tell the "RAW" images that are captured using the 570IS are not standard Canon DIGIC RAW format. The only work around I could find is as follows:

    "As for RAW files, you can set it to take them but since we are technically cheating, Photoshop, Lightroom, and Bridge don't recognize the files it creates in RAW. I've had to use GIMP 2 and the UFRaw plug-in. Both are free to use and it will open your new RAW files."

    The information came from here: Talk:A570 IS - CHDK Wiki

    Hope this helps.

    Thanks Gordon,

    And I just found the same info an hour ago at CHDK Wiki. So I downloaded and installed Gimp 2 and the UFRaw plug-in. It does open the RAW files, but they still will not import into Nebulosity! And the saved versions of the RAW files from Gimp still don't open on the Mac. They only seem to be viewable in Gimp.
    Never thought I'd be pining for my old PC.....Nebulosity seems to be one of the only Mac compatible programs for this purpose, and it's proving to be useless.

    Dean,

    Exactly. That's the whole problem. The RAW files from your camera are not compatible with the DIGIC raw format. Try opening them in GIMP then do a 'save as' in a .tif format. That should open in Nebulosity etc etc.

    Hi Gordon,
    Thanks for the tip. Unfortunately, Gimp won't let me save in .tif or anything else. The save options are greyed out.

    In GIMP can you export them?

    Hi Kevin,

    I can't even find an export command option in any of the menus in Gimp.
