HDR and camera evaluations


Geoff Boyle
 

I’ve only had a quick look at this but I thought that you’d like to see the preliminary results…

 

I’ve only looked at the Alexa so far, I’m using Resolve in ACEScct and the only grade I’m doing is a timeline colour balance to make the T16 Kodak Grey neutral.

 

Viewing is an Eizo CG318 which is 31” 4K and HDR 350, however it can simulate PQ1000.

 

With the ODT set to 709 and the monitor to 709/1886

 

Best overall look is at T16

 

Highlight retention is T11

 

Shadow detail is T32

 

With the ODT set to Rec 2020 ST2084 1000 P3 gamut clip and the monitor set to PQ1000

 

Best overall look is T11

 

Highlight retention is T2.8/T4 split

 

Shadow is still T32

 

With the ODT set to Rec 2020 and the monitor set to HLG

 

Highlight Retention is T8

 

Shadows still T32

 

The simple answer is that, bearing in mind the best overall image on screen, HDR has one stop more useable shadow detail and two and a half stops more highlight detail.

 

Or, three and a half more stops which kinda agrees with the numbers, rec 709 100nits, HDR 1000nits

 

Visually the difference is stunning.

 

Cheers
