I am trying to figure out how to achieve a technically correct exposure, regardless of the scene. Is there a specific way to achieve exactly 42 IRE with the C70? C70 false color sets 18% grey at 39.8 IRE. Zebras are not as accurate. 42 IRE is about 0.25 stop...
The asterisks (*) next to sRGB and Rec.709 are references that indicate that these color modes are Calman Verified.
Considering a colour look for a creative project before production is an essential part of any process. Pixar, one of the masters of storytelling, creates a range of colour scripts before production even commences. These indicate the colour palette that will be used for each scene, ensuring ...
Rec.709 (now often called SDR) is expected to be "graded" on a screen with 100 nits brightness. It used to be called 100IRE brightness. Clear so far, right? Nits again is just a terminology change from an engineering type name to a video post user name. Same t...
SL-HDR2 is quite similar in concept to HDR10, but with the addition of dynamic metadata for improved scene-to-scene image quality. Unlike SL-HDR1, there is no SDR-compatible version, making it less desirable for broadcasters. Little is known about SL-HDR3, but it is believed ...
Then, at night shoot a scene with people maybe before a fire, using D-Log, Normal and Low Light. In any case remember to create a proper project that matches the color profiles you recorded with. Finally, I find that when applying the D-Log to Rec. 709 LUT that DJI gives us for ...
The S-Log format by Sony, for example, is a gamma curve with a wide dynamic range and color gamut greater than the Rec709 color space. During color grading, the colorist, therefore, has greater artistic control to achieve the desired look....
Real Scene Brightness: 1,810 cd/m2 HDR Image -TCL 4 Series/S446 2021 QLED Contrast:1,253:1 Real Scene Brightness: 228 cd/m2 Peak brightness is probably one of the most important aspects of HDR. This is where high-end TVs have the biggest advantage, as HDR content makes use of their...
最理想的情况是使用HDR同款监视器,这样能够最大程度保持色彩一致性。当作SDR监看时,需要将其设置为Rec709 Bt.1886/Gamma 2.4, 100尼特,Full Range或SDI Full Range。这会帮你省下很多不必要的时间来匹配不同监视器之间的色差,这也是最为常见的潜在问题。
Dynamic range refers to the range of the brightest and darkest tones that can be captured by a camera. Not like human eyes, the camera delivers a very narrow dynamic range. Therefore, it is hard to photograph a high-contrast scene with details remained. To set dark partial as the focal ...
