Sample footage, Sony a7 III HLG HDR. To be seen correctly, must be viewed on an HDR display. SDR (standard dynamic range) rec. 709 video contains at most around six or seven stops of dynamic range while HLG HDR video is capable of as many as 17.5 stops – though both the Sony and my LG C7 OLED TV probably max out at somewhere around ten. Meaning you can see massively more detail in highlights and shadows, an example of which can be seen in the shot of the alley, where direct sunlight is hitting the wall yet it is possible to see texture and there is even detail in the darkest shadows. Specular highlights are more realistic and intense. And because of the insane black levels, next to no blooming of highlights and superb local contrast of OLED displays, images appear incredibly lifelike and detailed. Footage shot with ordinary glass like the FE 85mm looks like it was shot with Zeiss Otus (exaggerating a bit, but you get the idea!). And that is with in-camera sharpening dialed all the way down to -7 and no sharpening added in post. YouTube’s HLG is vastly superior to either 1080p or 4K.
