How to watch HDR photos on HDR TV…

Hello,

Hdr TV’s are available already about 10 years.

HDR photos also exist quite long. There are different 10/12 bits RAW file formats from DSLR and Mirrorless cameras. And 10 bits HEIC/HEIF file formats, produced by phone cameras and Mirrorless cameras from Sony / Canon / Nikon. 
I wonder why is still so little interest in displaying those files especially HEIF on HDR TV?
i tried to google this topic and found literally nothing.

So i have about 4 hardware players connected to my TV. Nvidia Shield TV, Fire TV 4K, Dune 4K, Intel Nuc…

Tried different photo viewers on all them today. And they even couldn’t recognize HEIF files.

But the requirement is not only recognizing but also to send HDR metadata to TV so it can switch automatically to HDR10 mode!

is this really so bad, and no solution yet? Why HDR photo is not as popular as HDR video?

HEIF files are still Apples domain... I bet if you hooked up an AppleTV you'd be able to view them.

Personally, I convert any family provided iphone HEIF's immediately to TIFF and delete the HEIF's... I like universally accepted formats over proprietary ones... problem solved.

You actually cannot view them even with an AppleTV. Yes, the AppleTV “Photos” app will display iPhone Dolby Vision videos in HDR, but not the HDR HEIF still files from the same iPhone. Those display in SDR. Why does it not support this? Who knows.

I don't think Linux or Windows can display anything other than 8 bit with high bit depth supported monitors and graphics cards. And online photo sharing sites and web browsers don't support them either.

because you can't mix the two - one is source processing, and the other is output processing,

You can do the output processing to photos too(technically speaking), just nobody makes tools to do it.

If OLED TV has 10 bits panel - it should be very simple to output 10 bits photos.

Viewer just should use RGB10 surface instead of RGB8. And probably should send some meta data to HDMI to switch TV to proper mode.

But I thing there is even no standards for TV’s to display HDR still images. But there are over four HDR standards to display HDR video. HDR10, HDR10+, Dolby Vision, HDR HLG, …

And BTW heif is not apple proprietary format. It was introduced by MPEG group in 2015.

But unlike jpg is not widely supported by photo viewers yet.

Some viewers support heif from iPhone, like ACDSee. But do not support HDR heif from Canon EOS R5. Which is out of my mind. Both are HDR.

that's like saying an amp should be very simple to go louder if the knob can go to 11
