![]() Nowadays movies even have 4DX ( HERE), which go beyond visual and auditory signals.ĭiscussion has to be reopened and the use of bt1886 gamma reevaluated.Ī gamma standard that wants to emulate a "perfect" gamma 2.4 device and suggests an average that is closer to PLG (Power Law Gamma) 2.2 on an "oled level grading device" (0.02 nits black) is a joke.Ī gamma standard that jumps from an average near 2.2 (oled mastering standard) to an average near 2.4 in one case and one case only (once black approaches 0,00002 or below) is a joke.Ī gamma formula that suggests it can both emulate CRT characteristics and on some devices produce a perfectly linear 2.4 gamma at the same time, is a joke.Ī gamma standard that introduces luminance differences of +200% at 5 IRE and +26% at 30 IRE in TVs released in 2016 alone is a joke. I get it, it's all about sensory DYNAMICS! That way I can see and hear everything without being too attentive or on a sensory overload. I lower the gamma to 1.80 or lower, and super compress the audio so that explosions and whispering are practically the same. To add to that, for casual daytime on secondary monitor watching I do exactly the opposite. Yes, I realize I'm being captain obvious here, but my point is if movies were mastered with gamma of 2.2 for dim domestic ambient lighting, then lowering the ambient light to even darker means we can raise the gamma value and get even more "popy" or "contrasty" image with the same contrast ratio display/projector while preserving the colorist intention. ![]() I think the main factor of what gamma looks natural to our eye is the ambient light, the darker the room the higher the gamma that looks natural to us. In a fully dark room I can set the brightness to -70 which translates to around 3.2 gamma and have a very beautiful picture, although I find that I need to raise the black level +3 click so step 16 is visible. Gamma of 2.6 would be -25 brightness, 1.8 would be +25, each 0.1 gamma step is 6.25 on the brightness. * The Brightness control in MPC-HC with MadVR is actually a Gamma control and let me play with any gamma value I want. Then I play a movie with a dark scene and turn the gamma up till the dark scene looks natural and not overbright.Īlso, a nice side effect of higher gamma is more saturated colors as they have smaller range to from dark to bright,yet still a natural transition unlike increasing the saturation control. What I do is completely eliminate all light source from the room including the keyboard Num-Lock led and let my eye adapt to the very dark room. I have discovered that when the eye is completely adopted to darkness I can watch movies with 3.0 (not a mistake) gamma without loosing any shadow detail and having almost blinding white level, very contrasty picture yet still quite natural on skin tones. ![]() I've been playing with gamma recently and trying to figure what the eye likes at what environment light level.Īlthough we're at the dawn of a new era of ST.2084 which defines precise light output level for each input word, Gamma is still the standard for SDR displays and it is not as concrete.
