When shooting RAW, the OM-D records 4:3 files no matter what the aspect ratio is set to. If you set it to 3:2 (for example), the camera records some sort of metadata to communicate this information to Lightroom, which honors the setting. So far, so good.
My question is, is there any way to override that setting? I have a photo shot at 3:2, but I can see from the in-camera preview that it'd be a better shot with the whole thing. But I can't figure out how to get LR 4.1rc2 to show me the whole thing!
Unfortunately, there is no way in LR directly. You may be able to restore the settings directly in the raw file using exiftool (tags "aspectratio" and "aspectframe", there are instructions in some forums I think), but it is generally not advisable to manipulate original raws that way (at least, a backup should be made).
It would be great, if the aspect ratio meta data from the raw file was mapped to the "Crop Overlay" tool in the Develop section. If the import just converted the information to a crop overlay development step, it could be easily altered later on.
Totally. In fact, I half expected that to be the case already.
By the way, the magic incantation seems to be:
exiftool -AspectFrame="0 0 0 0"
It doesn't seem to work on DNGs, which is unfortunate since I am in the habit of converting to DNG on import. For now, I am simply shooting in 4/3s format. It is, after all, the camera's native format; and perhaps I will come to love it.
I created a little LightRoom plugin, which automates the exiftool process and stacks the new raw on top of the old one:
It's my first LR plugin, so it is quite possible that it still is somewhat buggy. So far I only tested it with Olympus ORF raws.
Have you tried if it works? I think the plugin should be independent of the extension:
local ext = LrPathUtils.extension(path)
local newPath = LrPathUtils.replaceExtension(path, ".deaspect."..ext)
LrTasks.execute("exiftool.exe -AspectFrame=\"0 0 0 0\" -o \""..newPath.."\" \""..path.."\"")
I've used exiftool directly on DNGs, using the same arguments I used to fix ORFs, and it didn't work. It produces no error message, and creates a new file and everything, but the crop doesn't change.
Also, if I'm not mistaken, your plugin won't work for me at all, because my copy of exiftool is just called "exiftool", not "exiftool.exe". I'm on a Mac and I installed exiftool using MacPorts.
I updated the tool according to your input, now it should work on mac and I succesfully tested DNGs on windows.
Can you please try and see if everything works on your side? Thanks.

Now when I try it on a photo (which happens to be DNG), I get a dialog box:
An internal error has occurred.
LrCatalog:addPhoto: no file at path
Can't try it on an ORF right now, my baby's demanding attention ...
