I shot RAW images on a Canon 5D Mark III using the camera’s 1:1 aspect ratio setting. In camera and in Finder, the files preview with the full 3:2 frame, but when I open the CR2 files in Adobe Camera Raw, the images are constrained to the 1:1 crop and I can’t expand them back to the native sensor area. Is there a way to recover the full 3:2 framing from these RAW files?

So the only solution appears to be:
- Install Exiftool (Free)
- Open Terminal and navigate to the directory containing the image(s):
For a single image called
BD3A6291.CR2with dimensions of 5760 x 3840 execute:exiftool BD3A6291.CR2 -AspectFrame="0 0 0 0" -DefaultCropOrigin="" -DefaultCropSize="" -CroppedImageWidth="5760" -CroppedImageHeight="3840"

Yes. The RAW data is still there, but Adobe Camera Raw is honoring the crop metadata written by the camera. Based on the community solution, you can remove or reset that metadata with ExifTool so ACR shows the full uncropped frame again.
For example, for a 5D Mark III file at 5760×3840, run ExifTool on the CR2 and clear the crop-related fields:
- reset AspectFrame to 0 0 0 0
- clear DefaultCropOrigin and DefaultCropSize
- set CroppedImageWidth to 5760
- set CroppedImageHeight to 3840
That removes the in-camera 1:1 crop instruction and restores the native 3:2 view in ACR.
Before editing metadata, make a backup of your RAW files. If you have multiple files, apply the same process in batch with the correct native dimensions for your camera/files.
