I have a stack of RAW photos shot using the in-camera crop on the 5d Mk3 at 1:1 aspect ratio.

When I open them in ACR, I am unable to open out the crop to the native (3:2) aspect ratio. The image previews in-camera and in Finder show these images in their 3:2 entirety.

How do I get these photos back to 3:2?

  • Have you tried opening them in Canon's Digital Photo Professional? – Michael C Aug 31 '14 at 15:15
  • I've never even installed the Canon software, but thanks for the suggestion. I'll give it a go. What I'm confused by is that the data is still there, so why isn't the crop data editable in ACR? Surely that's the point of RAW; that data remains editable. – Undistraction Aug 31 '14 at 15:19
  • @Pedr The data is there don't worry. But Adobe applies the cropping you set in camera as default. – Hugo Aug 31 '14 at 15:35
  • Adobe products ignore most of the maker note section of the EXIF info. I suspect that is where your problem lies. When you first open your files in DPP they will display in the 1:1 crop, but open the trimming/angle tool (Alt+C) and you should be able to change it. – Michael C Aug 31 '14 at 16:08
  • @MichaelClark Opened in DPP, cleared crop info so that it shows original 3:2 and saved as a new file. However ACR still opens it with 1:1 crop applied. – Undistraction Aug 31 '14 at 16:21

So the only solution appears to be:

  1. Install Exiftool (Free)
  2. Open Terminal and navigate to the directory containing the image(s):
  3. For a single image called BD3A6291.CR2 with dimensions of 5760 x 3840 execute:

    exiftool BD3A6291.CR2 -AspectFrame="0 0 0 0" -DefaultCropOrigin="" -DefaultCropSize="" -CroppedImageWidth="5760" -CroppedImageHeight="3840"

  • Nice! It's been a while - want to mark this as accepted? – Cullub Feb 27 '15 at 16:55
