“Is the Barten Ramp the correct threshold?”
The Barten Ramp is calculated from P. G. J. Barten’s 1999 Contrast Sensitivity Function (CSF), a model that supposedly incorporated most of the important variables in the ability of the HVS to detect contouring in digital display systems. Note this is modeled rather than measured data and the model is based on data that predates... Continue Reading →
“Television Better Served By HLG“
“The PQ system was developed by Dolby, a company whose main focus is on the cinema while the HLG system was developed jointly by BBC and NHK, two organizations whose main focus is on television… Television is probably better served by the HLG system that was designed from the ground up by television engineers for...

Narrow vs. Full Range

Cinema Camera WCG Capability
Shane Mario Ruggieri, in his podcast with Mixing Light, said that not all cameras with high dynamic range can capture very saturated, accurate colors at high luminance levels. The diagrams illustrate the light gathering ability of a few cinema cameras capable of recording between 11 and 12 stops of dynamic range (Imatest). The OG Sony... Continue Reading →
“10 Stops Is Perfectly Good”(Provided You’re Confining Yourself to SDR Levels)
What cameras do you normally come across when you're working in HDR? Is there any specific camera that's worked really well for you? Are there cameras that are problematic? "I remember something that Bill B., the guy who put me in the business, he told me something when I asked him what camera I should... Continue Reading →
Want to enjoy your HDR videos in a bright viewing environment? Shoot HLG!
“With both PQ and HLG, if video content is displayed at the same brightness and in the same viewing conditions as those in which it was produced, it will look the same as it did on the production monitor. The creative intent will be maintained. Indeed, under these conditions PQ and HLG deliver identical looking... Continue Reading →

How to save trimmed R3D files in DaVinci Resolve
Go to File > Media Management > Press Start Mission completed! The .RDC folder containing the R3Ds and .rtn as well as the .drt have been saved.
“The most important aspect of any TV system is the OOTF”
In their Quick Start Guide to DaVinci Resolve Studio, Dolby Vision says to set the input and output DRTs to none on the color management page, which is why we're guessing that they wouldn't be overly fond of choosing tone-mapping in Resolve's OFX CST either - but there's no prohibition against OOTF that we're aware...

QD-OLED vs. WRGB OLED: Red, Green & Blue Pixel Luminance
"On QD-OLEDs, the peak brightness is the sum total of the red, green and blue outputs.... By contrast, [...] WRGB OLEDs use white subpixel boosting to achieve higher brightness, so if we do the same measurements of red luminance, green luminance and blue luminance on a WRGB OLED television, you will see that they only...

Nonsense About Display-Referred Workflow
If you even think about this for a second, you realize it doesn't make sense. “If we start with the concept of a display referred workflow, […] it basically comes down to this idea of working in a color space that matches the output display. In other words, the physical device on which the end... Continue Reading →
