User manual

boosts or lowers the maximum value of the corresponding color channel, and scales
the midtones while pinning the bottom of the channel to 0 percent. Lowering does the
opposite. The overall range is 0 to 10, where 1 is unity.
•
Contrast — Available in the RED cameraʼs Color menu. Raising the contrast boosts
the highlights and lowers the shadows, while leaving the midtones centered around 50
percent unaffected. As the video signal reaches the boundaries of 100 and 0 percent,
itʼs compressed rather than clipped. The overall range is –1 to +1, where 0 is unity.
•
Brightness — Available in the RED cameraʼs Color menu. Raises and lowers image
lightness. When raising the signal close to 100 or lowering it down to 0, the image is
compressed rather than clipped. The overall range is –10 to +10, where 0 is unity.
•
Gamma pop-up menu — In-camera, the Gamma setting is determined by the Color
Space option thatʼs selected in the RED Cameraʼs View menu (itʼs not available as an
individually adjustable parameter). There are six options for gamma available in Color.
•
Linear Light — No gamma adjustment is applied at all, linear-to-light as captured
by the Mysterium sensor.
•
Rec. 709 — The standard gamma curve as specified by the Rec. 709 standard for
video gamma.
•
REDspace – Similar to Rec. 709, but tweaked to be perceptually more appealing,
with higher contrast and lighter midtones.
•
REDlog – A nonlinear, logarithmic gamma setting that maps the native 12-bit RED
image data to a 10-bit curve. The blacks and midtones that occupy the lowest 8
bits of the video signal maintain the same precision as in the original 12-bit data,
while the highlights that occupy the highest 4 bits are compressed. While this
reduces the precision of detail in the highlights, this is a relative loss as the linearly
encoded data has an overabundance of precision.
•
PDLOG 685 – Another logarithmic gamma setting that maps the native 12-bit RED
image data into the linear portion of a Cineon or film transfer curve.
•
Color Space pop-up menu — These options are available in the RED Cameraʼs
View menu (in-camera these options are tied to corresponding Gamma settings).
•
CameraRGB — Identified on the camera as RAW, this mode bypasses the RED
camera matrix and represents the original, uncorrected sensor data.
•
REDspace — Fits the raw RED image data into a color space thatʼs larger than
that of Rec. 709. Appropriate for digital cinema mastering and film output.
•
Rec. 709 — Fits the raw RED image data into the standard color space specified
by the REC 709 standard for high definition video. Appropriate for HD video
mastering.
•
ISO pop-up menu — A gain operation (similar to Exposure), which pins the black
point at 0 while raising or lowering the white point of the image, linearly scaling
everything in between. The range is 100–2000; 320 is the default unity gain setting (no
change is made). Raising the signal too much can result in clipping.
