User Manual

 Gamma: Five gamma settings are available, depending on what starting point you want
to use for further grading.
–
2.4: A simple power-function gamma setting commonly used for broadcast.
–
2.6: A simple power-function gamma setting commonly used for digital cinema
projection.
–
Rec. 709: A gamma of 2.35, with a linear segment near black, approximating the
EBU recommended gamma for broadcast.
–
sRGB: A gamma of 2.2, with a linear segment near black, intended for reproduction
on computer displays alongside the sRGB color space.
–
Linear: A simple linear gamma setting.
–
Blackmagic Design Film: A log-encoded gamma setting that approximates Cineon
encoding, the main difference being that more data is encoded in the darkest
portion of the Blackmagic Design Film signal. When you choose this setting, the
appropriate variation of gamma will be applied based on your particular sensor, be it
4K or 4.6K.
–
Blackmagic Design Video: A normalized gamma setting that provides a fast starting
point for grading if you don’t want to begin with a log-encoded image.
 ISO: A gain operation that keeps the black point at 0 while raising or lowering the white
point of the image, linearly scaling everything in between. Raising the ISO can push
image values above maximum white, but these values are not permanently clipped and
are retrievable using the Highlights parameter or using later adjustments. This control’s
default value and range is dependent on the type of camera the media was shot with.
You should also know that different log curves are applied to 4.6K media depending on
which ISO you choose, to deliver the best possible output.
 Highlight Recovery: A checkbox that lets you include additional highlight sensor
data that’s usually clipped by the standard decoding matrix. In cases where you have
extremely clipped highlights, you may obtain additional image detail this way, although
it may contain unusual color artifacts.
 Tint: Color balance correction for images with a green or magenta color cast, such as
fluorescent or sodium vapor bulbs. 0 is unity. The range is –150 to +150.
 Sharpness: A debayer-specific sharpness filter applied to provide the appearance of
enhanced image detail. 20 is unity. The range is 0 to 100.
 Highlights: Makes it easy to selectively retrieve blown-out highlight detail in high-
dynamic-range media by lowering this parameter and achieves a smooth blend
between the retrieved highlights and the unadjusted midtones for a naturalistic result.
0 is unity. The range is –100 (minimum) through +100 (maximum).
 Shadows: Lets you selectively lighten or darken shadow detail. Raising this value
retrieves shadow detail recorded below 0 percent, while leaving the midtones alone.
0 is unity. The range is –100 (minimum) through +100 (very high).
 Color Boost: Lets you naturalistically raise the saturation of regions of low saturation,
sometimes referred to as a vibrance operation. Can be used also to lower the
saturation of regions of low saturation. 0 is unity. The range is –100 (minimum) through
+100 (very high).
 Saturation: Adjusts the color intensity of the image. 0 is unity. The range is
–100 (minimum) through +100 (very high).
