Canon G12 4:3 Raws import to LR at 3:2

Apr 27, 2012 7:44 PM

Tags: #lightroom #raw #g12

1. Shot Raw+jpeg captures at 4:3 camera setting

 

2. For the Cr2 (not the jpeg) EXIF Tool shows EXIF image W&H as 3,648 x 2,736 (4:3)

 

3. Cr2 opens in Irfanview at 4:3 aspect ratio, exif reads full 3,648 x 2,736 (4:3)

 

4. Cr2 imports into LR "cropped" per se to 3,648 x 2,432 (3:2)

 

Tried in LR 3.3, also LR RC 4.1 w/ ACR 7.0

 

I want to be able to work with the full image data in Lightroom.

Thanks for any help.

    If you've set the aspect ratio in-camera to 3:2, LR will respect that even in the raw data.  Was your JPEG 3:2?

    Thanks, see above, camera set to 4:3 and the raw file is 4:3, as evidenced in exiftool and irfanview. Lightroom is treating it as 3:2

    I don't see how that's possible since the G12 has been out for a long time and no one else has reported it.  If you have a problem image, I suggest you upload it.  If this is happening to all your images, something is weird somewhere.

    good grief, we brought the file in question into DPP and it had white crop box for the aspect. We clear that, tagged it as 4:3, saved the RAW, and then LR finally recognized it as 4:3, but only in the preview, as soon as it actually brought it into LR, it snapped back to 3:2. So still not working. Any thoughts. LR3.3, ACR 6.6, assuming it's not a matter of old LR or ACR. Any help greatly appreciated. Thanks

    Okay, so it was set to 3:2 in-camera, and yout tried to use DPP to re-save the metadata so you could access it in LR?  If that didn't work, my only suggestion other than to wait for new functionality it to do a search for "DNG recover edges".

    In another forum someone reported that it is possible to reset a G12 CR2 to 4:3 with the following exiftool command:

     

    exiftool -AspectRatio=4:3 -CroppedImageWidth=3648 -CroppedImageHeight=2736 IMG_nnnn.CR2

     

    Note: Make a backup of the original file! Modifying the metadata of raws is inherently dangerous (although exiftool is quite reliable).

     

    P.S. There are two problem reports in the feedback forum on this. I made a proposal how to better handle the in-camera crop settings here: http://feedback.photoshop.com/photoshop_family/topics/lightroom_4_1_rc _trouble_with_canon_5d_mark_iii_aspect_ratio
