Im working on a final project for college, so fast replys would be appreciated if able

Im having an issue with lightroom very slightly cropping my images, and I have been unable to find a way to restore the full resolution. Ive attached some screenshots showing the raw files in explorer, the import settings, and the files in library with the changed dimentions. Ive already looked at a lot of guides having simmilar but not the exact same issue, and no fixes ive tried have worked.

I tried just resetting the crop in the develop module but it doesnt show any crop to reset, Ive tried a very old plugin to restore edges and that didnt work either. I dont think its a camera setting as the actual raw file has the expected resolution, its just lightroom thats cutting it down. I also have made sure there is no lens correction being applied either.

Im at a loss here, any help is appreciated

I was having a similar issue. What I found to be the culprit was this setting under "Optics". It had 'Distorion Correction' at nearly 50%. This was causing my image to be automatically squeezed down and causing a headshot I took to be cutting off. Once I changed that to 0, it brought the image back to normal.

Running Canon R5 MII, with RAW .CR3 files, just a FYI.

The EOS Ra is no diferent to the EOS R in respect to its RAW image size as specified by Canon: 6720 x 4480

In both cameras, the actual sensor pixel width and height is larger: 6888 x 4546

The Exif data specifies the left image area starts at 156 and the right is 6875, giving a width of 6720. The top image area starts at 58 and the bottom is 4537, giving an image height of 4480.

LrC complies with Canon's specifications. Deep Sky Stacker does not and neither does Windows. Dark Table also comes up with 6742 x 4498, while Raw Therapee does its own thing, coming up with 6734 x 4490.

LrC is not cropping, the others are sampling outside the manufacturer's specified image area of the sensor.

The Canon EOS R RAW file is 6720 x 4480 pixels, which is what LrC is reporting and what is recorded in the .CR3 file's Exif data.

Why Windows Explorer is different is any one's guess, but you will find that it's not 6742 x 4498.

Your images are not being cropped by LrC on Import.

Deep Sky Stacker(astrophotography software) is reading my calibration frames as 6742x4498 as well, and same for these light frames if I load them into DSS before importing them to lightroom. Its problematic because DSS wont stack images if the resolution is mismatched, and im not getting the quality I want out of the stack with the unedited RAWs, so I have to pass them through lightroom first to make some edits. Im also shooting on an EOS Ra, which does have a slightly modified sensor from a EOS R, so it might shoot at a different resolution
