It’s just Microsoft being too cheap to pay for their own RAW parser, like (for example) Apple does. That would be an understandable sacrifice if Windows 10 itself was open source, but it’s not. Download from Windows Store If you experience difficulties downloading or installing the product, please contact. (Their closed-source FastRAWViewer does have preliminary CR3 support, so I assume libraw will gain the support eventually.) Microsoft’s RAW support will therefore remain incomplete indefinitely. Windows RT, Windows 8 and Windows 10 Download RAW Image Viewer from Windows Store by clicking on the link below, or Windows Store icon. CR2 thumbnails taken with my old 600D just fine, but cannot do the same for photos taken with 6D Mk II. It doesn’t reflect well on Microsoft that it took them until 2019 to try to address RAW files, and when they finally did, they decided to be lazy and rely on libraw’s clean-room reverse engineering efforts, instead of signing NDAs with the camera makers and implementing the actual written specs.Īs much as I admire the efforts of the libraw authors and the determination to keep things open source, their support sometimes lag the latest state of art by quite a bit-for example, the published version of libraw as of today still does not support Canon CR3, which is used in EOS M50, R and RP. 1 So it seems that for newer Canon cameras, Windows is no longer supporting codec updates which would allow the newer RAW files these cameras generate to be viewable in Windows file explorer as images in the icons view.
