Hi  I have just had a new camera and when looking at files on my laptop some are not opening correctly.  They do open ok in Canon DPP4 and Microsoft photos the files I am trying to edit are raw files, the screenshot attached is a .jpg.

Can anyone help please

Can you upload that particular CR3 file (shown above) to the forum?

Original CR3 file.    I took 13 photos just testing my new camera 8 of which have the same issue when using the longer focal length 132plus and opened with Affinity photo. All 13 images look ok through the view finder of the same image opened in Canons DPP4 it also opens okay in Microsoft photos. I just prefer to edit the raw files in affinity those taken between focal length 18-71 look fine

Not seeing any problems here, I am on Mac OS 11.6.1

I changed from the Apple engine for raw to Serif's engine for raw and there was no change, I turned on and off various lens corrections and there were changes but nothing like what you see.

I would suggest you make sure that the lens in the listing is in actual fact the lens you used. Canon EF-S 18-135 f/3.5-5.6 IS STM 

And finally you could try turning off the hardware acceleration in Preferences.

I have never mastered color management, period, so I cannot help with that.

Aside Old Bruce's hint: Months ago I experienced such a circular shape with CR3 files from a new camera which had not yet its lens profile implemented in APhoto. In that case it was possible to adjust it manually within APhoto. From the displayed pixel dimensions it appeared that macOS and DPP were able to read the lens distortion info saved with the image while APhoto did not, and thus the image was opened in APhoto with larger pixel dimension whereas it has been cropped during lens correction in macOS and DPP.

Note that your image in APhoto has 5120 x 3414 px, compare the size of this image corrected in macOS or DPP, I suppose the latter are smaller. The dimensions in your screenshot give the impression the images were taken as C-RAW or S-RAW in the sake of lower resolution and smaller file size. Just in case, and not related to this topic actually, you might want to read this article about these special kinds of RAW formats, in particular concerning compression / quality. If you need to take pictures in smaller file size then it may appear even useful to take them as high quality JPGs.

4) sRAW is NOT RAW

An uncompressed RAW / NEF file contains 14-bits of data per filtered pixel, so color and luminance information is demosaiced by software to form RGB pixel data. When you open a RAW file in Camera RAW or Lightroom, the software reconstructs the image in color by using a demosaicing algorithm on the bayer pattern. An sRAW file is already demosaiced and reconstructed by manufacturer’s camera firmware, so it does not contain most of the information from the RAW file.

Are you using an adapter ( EF-EOS R: C ) to adapt a APS-C lens to your full frame mirrorless? Reading up on your camera, it must use the RF mount lenses., unless you use the mentioned adapter.

Thank you all for you help.

My os is Windows

My lens is EF-S18-135mm F3.5-5.6 IS STM

Excuse my ignorance Old Bruce but not sure where to turn off the hardware acceleration in Preferences

I have selected raw files in camera not c - raw cannot recall seeing s - raw option

I am using a MOUNT ADAPTER EF-EOS R

Thanks Joan

I'm still thinking that it has to do with an APS-C designed lens used with a full frame body. What you're seeing is common when this is attempted. I think the adapter just allows you to mount the lens to your body.

About the only workaround I know of, is to crop it.

EDITED:

When you use a full-frame lens on a APS-C (Crop Sensor) body, the lens provides more light than the sensor has space. So that area outside the physical dimension of the sensor is just not captured, ie; cropped out by the camera.

Reverse that, using a lens that is designed to be used on APS-C camera bodies, and put that on a Full-Frame body, then the lens does not provide enough light to cover the size of the full-frame sensor. So the result is the black area, where there is no light (data) for the sensor. Thus the vignette effect.

It's not Hardware Acceleration as I don't use it and I see the same as you, using the Canon EF-S 18-135 f/3.5-5.6 IS STM lens profile (see image below)

If I select the profile above it (Canon EF-S 18-135 f/3.5-5.6 IS) the problem disappears

With activated hardware acceleration the image appears to me 'normal' if I choose a slightly different lens profile. At first this CR3 opens as shown in your screenshot and with your according lens correction activated, deactivating lens correction doesn't change the round shape. If I switch to the lens version USM (instead STM) the image switches to rectangular and if lens correction gets deselected now shows a minimal change in its center only. The someway confusing part is that deactivating both the lens correction AND the profile now doesn't show the initial elliptical shape but remains squared, whereas if I switch back to your STM lens it occurs again, with or without lens correction activated.

The Exiftool reports for this file "CRAW" * / "compression JPEG" / Image Size "5088 x 3392".
*edit: after an update of the Exiftool the type is reported now as "CR3", ".CRX" and "Compressor ID CRAW"

Considering that your camera can output images larger than 8000 x 5000 this size appears to be reduced, quite likely caused by the fact that it needs to get cropped because of the lens, as @Ron P. pointed out. The technical data seem to note this image size in particular as "1.6x (crop)" which would mean only 2/3 of the full format sensor may be used for an image with this lens / adapter.

Thank you the lens data is correct.  Not sure where to turn off hardware acceleration is this in windows?

Thank you all for your generous help

 

I have checked the lens and what I used was correct although as Carl mentioned if I select (Canon EF-S 18-135 f/3.5-5.6 IS) it does indeed give the rectangle.

I have compared the exif from Canon DPP4 (attached)and checked the crop being 1.6 and the file is RAW.  I also noted the comments regarding the size of the file being reduced.

I will try some more practice with my other lenses and take on board all of your comments and maybe realise they may have to go in favour of buying new lenses for the R5.

Thank you all once again for your assistance it is much appreciated.  Shame Canon are not so helpful when selling the adapters but I keep learning

Regards

Joan
