Canon R5 Mk II and display issues with Windows 11

[BWCorpus]

Picked up an r5 Mk II for a Australian trip and the while I love the camera, the

raw images are not displaying well with my Win 11 laptop. The image come up ok, then switched to this after about a second.



Any advice on an updated video driver would help!

It looks like the raw file format is too new for Windows, so it assumes that the black level is 0 in the raw image, when in fact it should be 512 or 2048. So, it is doing a conversion on the raw data that adds a blanket of false light on the image, which turns to a purple/magenta cast after white balance. I have never used the OS for looking at raw files, so I don't know if there are any settings you can use to tell windows to just show the embedded JPEG. You can, of course, assign another app to open the images, like Irfanview or Faststone Image viewer, both of which show the embedded JPEG images by default. FastRawViewer is another app that you can use, and choose between its conversion and the embedded JPEG (its raw converter is pretty literal, and does not do lens corrections or noise reduction or sharpening).

This has nothing to do with a video driver. It's Windows' image codex for R5-II files that needs to be updated. The programs I mentioned can be slow at adopting new cameras for raw conversion, too, but they do allow you to choose the embedded JPEG.

Another clue that Windows is confused by the raws is the presence of those borders on the left and top; those are pixels normally in a raw file, but cropped away in a converter, because they are masked over and never get exposed to light, and they should be at the black raw level.

It has nothing to do with the video driver - for a quick solution, download DPP (digital photo professional) software or one of those suggested above by John Sheehy.

Another note - critical workflow should have been tested before the trip (e.g. how you manage your images).

The Windows Photos app can open CR3 files if it you have the latest codecs; it opens the embedded JPEG preview first then opens the raw data and tries to open the RAW data and apply automatic contrast enhancement. That can do spectacularly wrong with high contrast images like that that sunset and astro images but it is what it is. For example,




Exported as JPEG from Windows Photos




Exported from PhotoLab 7 with lens corrections, 16:9 crop, +1 stop expsure increase, DeepPRIME XD noise reduction

If you open a CR3 file that's been made with a lens designed for electronic distortion correction you can see the whole shape of the image change as it goes from the JPEG preview to the RAW data. The colour changes are little more subtle than what you get if you open an image on the GIMP then go <Colors> <Auto> <Equalize>, but the Windows Photos app is just about my least favourite method of viewing RAW files.

Does this happen in Explorer or in a specific application? If Explorer (and/or the native Windows Photo app), check that the RAW Image Extension is installed. You can get it in the Microsoft store or at the following link.
