.CR2 files incredibly dark for a while, .CR3 files not shown at all

[mattnoir]

QuickLook is not working for Canon RAWs as it should, they are either incredibly dark for several seconds (.cr2), or just show info and not the picture (.cr3). Checked with Nikon and those work as intended
I also have installed RAW image extension from windows store for .cr3 support

Desktop (please complete the following information):

• OS Version: Windows 10 2004
• QuickLook Version: 3.6.10 from windows store

.cr2

.cr3

The dark image you saw in the first seconds is the thumbnail extracted from the CR2 file. QuickLook uses Exiv2 to extract thumbnails and does not perform postprocessing: the dark thumbnail is from the original CR2, and I'm not able to fix that.

The same applies to CR3, which is not supported by Exiv2. I can add the support to QL but you have to wait for a few seconds to see the full image.

You can try out the CR3 previewing here: https://ci.appveyor.com/project/xupefei/quicklook/builds/35813695/artifacts
It will be slow nonetheless.

Thank you for clarifying this, however the thumbnail is not as dark (I would have problem with photos like that) at all and it was actually working well before (not sure when sadly), so I was just surprised that it now takes seconds to show proper picture. So unfortunately now I have to use xnview more, which is a few more clicks to close than just a spacebar.
Other than that, thank you for this amazing software
