User manual

For clips that were imported with native color metadata, the RED tab provides access to
the clip Color, Color Temp, and View metadata originally written by the RED camera.
However, this metadata can also be overwritten during ingest using a custom color-
processing option in the Log and Transfer window. These parameters are provided so
that you can begin grading each clip in the state at which it was originally monitored
during the shoot, or at which it was ingested using the Log and Transfer window.
Note — Although there is functional overlap between the controls found in this tab and
those found elsewhere in Color, the Kelvin and Tint controls are specially calibrated to
provide the most photometrically accurate white balance adjustments for RED
QuickTime media.
RED Image Controls
The RED tab has the following parameters and controls:
•
Enabled — Turns all of the parameters found within the RED tab on or off. Turning
Enabled off suspends the effect of these parameters on the final rendered image in
Color.
•
Saturation — This parameter is available in the RED cameraʼs Color submenu, and
adjusts the color intensity of the image. The overall range is 0 (monochome) through
5.0 (extremely high), where 1 is unity.
•
Kelvin — This value is set by options in the RED cameraʼs Color Temp menu, along
with Tint. This setting is designed to compensate for the “warmth” of the available
lighting to keep white elements of the scene looking neutral. Low Kelvin values will
compensate for “warmer” lighting (such as tungsten), while higher Kelvin values
compensate for “cool” lighting (such as noon-day sun or overcast days). Two user-
selectable options set Kelvin to predetermined values: Tungsten (3,200K), and
Daylight (5,600K). The Auto WB option automatically chooses a custom value for this
parameter based on analysis of a white card, while Manual WB lets the operator
choose any value. The correction made by this parameter is designed to work
specifically with RED linear light image data to provide the most photometrically
correct result.
•
Tint — This value is adjustable within the RED cameraʼs Color Temp menu, along with
Kelvin. Tint is designed as an additional white balance compensation for light sources
with a green or magenta component, such as fluorescent or sodium vapor bulbs. The
correction made by this parameter is designed to work specifically with RED linear
light image data to provide the most photometrically correct result.
•
Exposure — Available in the RED cameraʼs Color menu. Increases and lowers image
lightness in increments calibrated to ƒ-stops. When raising the signal up to 100 or
lowering it down to 0, the image is clipped at the boundaries of broadcast legality. The
overall range is –7 to +7, where 0 is unity.
•
Red, Green, and Blue Gain — Available in the RED cameraʼs Gain submenu. Allows
individual adjustment of each color channel. Adjusting any of these gain parameters
