The daily Perseverance Rover calibrated color images on https://areo.info/mars20 are now shown in Ultra HDR!

Since sol 1277 my site is publishing them now in this new format. Automatically works with Chrome, Opera, Edge and Brave on Macbooks and iMacs since M1 / 2020 and recent Android phones. On Windows only if an HDR-capable display is attached.

Now the full 12 bits/channel camera data can be seen for the first time on your web browser! Below a try to demonstrate the difference in a screenshot photo comparing standard JPEG (SDR) on the left and new Ultra-HDR on the right. But in reality it's much better, you have to see it yourself!

This is as far I know the first website showing the full capability of the 3 Navcam / Hazcam pairs on because without HDR on the display software and hardware side it was impossible to experience the full dynamic range the 12-bits per RGB color channel the original raw camera data provides. The other color cameras on board, Watson and Mastcam-Z have 11-bits/channel, Ingenuity Helicopter only transmitted in 8 bit.

The 3rd image below is one of the UltraHDR ones. It will only show the HDR effect when clicking on it to view the full size. On other browsers / hardware it will be shown as normal image without the additional extreme high contrast effect you get in a HDR capable system.

It's preparation for further HDR images from space. For example Artemis where Nikon Z9 cameras will be used, which are currently tested on the ISS. And those produce as raw format 14 bits/channel data, far more than any standard dynamic range display system where 8 bits are standard can show. For example with HDR, the lunar surface and stars are possible to show at the same time without overexposing the surface.
