Title: Test Pattern - ITU-R BT.2111 PQ 10,000 Nits (for testing Tone and Gamut Mapping)
Post by: jmone on May 30, 2023, 08:10:42 pm

I could not find exactly what I wanted to test JRVR's Tone and Gamut Mapping in a single test pattern, so I made this 1 minute one up.  Unless I've stuffed something up this should be the ITU-R BT.2111 PQ Test pattern (from Davinci Resolve's Pattern Generator) rendered out covering the full 2020 gamut / 10,000nits / 16-235 "video" range.  AKA - the most you would ever see on a UHD HDR BD.

Anyway, according to the spec it should display as per the attached pic when played on your display.

It certainly helps me see how JRVR's Gamut and Tone mapping algorithms and settings look on different displays.

Rrrr, I knew I'd stuff something up!  I used the wrong "Pattern Generator" in Resolve (selected Full not Narrow "aka" Limited).  Re-uploaded the test pattern in the original post.  Sorry.
