RAW files automatically cropped in LR when imported

Hi!

A very annoying issue that I know had been discussed a few years ago but I couldn't find a convincing answer...

I am using a Canon G7X (compact camera), shooting in RAW (cr2 file format)

When look at the preview in the default Windows app (Photos), the image is a bit distorted but full. When I import in LR Classic, it automatically must apply a lens correction which crops the edges of the picture quite agressively.

I've tried the workarounds I could find online (open in PS; change the "develop settings" to "camera settings" in Develop; create a default in preferences -> presets -> "Overall global setting for specific camera"...)

Nothing works and I have a little inform box in Develop->lens correction "built-in lens profile applied", saying when I click on it "Canon PowerShot G7X - This raw file contains a built-in lens profile for correction distortion and chromatic aberration. The profile has already been applied automatically to this image"

-> how can I avoid that from happening? I'm ok with the slightly distorted picture, but I need uncropped.

 

The info in the raw file is still there because I can see the whole picture when I open the raw with another software (Photos, RawDigger...)

 

It's very frustrating.

 

Any help would be greatly appreciated! Thanks!!!

On "The profile has already been applied automatically to this image -> how can I avoid that from happening? I'm ok with the slightly distorted picture, but I need uncropped." I think this is done in your camera so you would have to check with Canon.

What do you see when you go into the Cropping Tool in Develop? Do you see a crop of your original image?

On viewing in LrC, have you checked your Navigator settings to see if you are zoomed in? Is FIT selected?

I have a Sony RX100 M7 that is similar in size and shape.  It does the same thing as your Canon.  Part of the Canon and Sony lens magic is that camera firmware corrects for the natural distortion that comes with the complex lens design needed by such small cameras.   The camera bakes it into the image file.  As far as I know, it can't be turned off in either the camera or in Lightroom.

Building on Bill's comment, the camera has embedded its own lens profile in the raw file and automatically applied it, and LR won't let you disable it. Years ago, Adobe employee Rikk Flohr implied this was because Adobe was following the directions of the camera manufacturers:

https://community.adobe.com/t5/lightroom-classic-discussions/severe-color-shifts-from-raw-in-lrc-and...

 

You can manually disable built-in lens profiles by doing the menu command Library > Convert Photos To DNG to convert the .cr2 to a DNG.  Then use the free Exiftool to remove the lens profile:

 

exiftool -exif:opcodelist3= myfile.dng

 

Then remove the .dng from your catalog and reimport it.

 

I don't have any sample G7 X raws, but I do have a couple of G7 X II raws. In the screenshots below, I've overlayed the version with the lens profiles automatically applied with the version with the profile manually removed. The sample taken at the widest-angle focal length shows a lot of lens vignetting, and the lens profile corrects the distortion and crops out a fair bit to remove the vignetting:

The sample taken at the longest focal length doesn't show any vignetting, with the profile correcting the pin-cushion distortion from the center out, with very little cropping at the edges:

Thank you all. I think you guys nailed it especially you @johnrellis .

 

I found a "workaround" by editing in RawDigger, saving as TIFF, then import in LRC. Does the trick but cumbersome.

I will try your solution too @johnrellis. might be neater!

 

Below my 2 images to show the amount of crop automatically applied an why I really wanted to recover the edges 🙂

For the bit of nose and tail cut off, have you tried the Generative Fill tools in Photoshop?
