A while ago I saw Corry’s work in creating HDR emoji, and I thought I’d see if animated emoji would allow the same thing. I tried this for a little while and although it’s possible to upload an animated png to Slack, it will only display the first frame. I found the same thing with LinkedIn when I tried it there, but maybe someone else will find a platform where this works. I did at least verify that this renders in HDR on an M1 MacBook Pro running the latest Chrome.

Rotating HDR Earth (this might not display in HDR, depending on your hardware and software)

I generated this from the first animated GIF I found, using the following command line.

magick earth.gif -profile 2020_profile.icc -coalesce -evaluate Multiply 1.1 -evaluate Pow 0.9 apng:earth.png
