HDR experiment

I’ve tried my first HDR experiment on Vimeo, if you can stream HDR then please check it out…

It should be possible to download the original file as well.

 

As it says on the page _ This is my first attempt to upload an HDR file.
It's PQ2084 1000nits and is the end of the presentation that I did at IBC 2018
The intention is to show the difference between SDR and HDR from the perspective of a cinematographer protecting their highlights as they usually do.
The result is that the highlights stay roughly the same but that the shadow detail hugely increases.
This is the opposite of everything I read about HDR giving you way more highlights...

Annoyingly Panasonic have removed the Vimeo app from the App Store so I can’t help :-(

Hmmm. I’m curious about this. Did you protect the highlights during shooting? Anything above 90% reflectance should land in HDR territory.

 

And yes, HDR highlights get a lot of press because they are fairly consistent across TV sets, whereas HDR shadows get less credit because they aren’t as stunning unless you view them on an OLED. They’re so deep that a lot of colorists say that they don’t like grading HDR blacks as pure black as they can be very disturbing. They always like to see some detail.

 

It’s a good idea to halve your ISO, as noise becomes pretty obvious. I just shot some test footage this way for an HDR grade and it turned out well.
