FLUT
You can adjust the following:
ISO (Native): Adjusts the camera’s native ISO value. RED recommends that you set the ISO near 800, then
adjust the lens T-stop and lighting or ND filters to match. The ISO can later be adjusted around one stop
for fine-tuning. Range is ISO 250–12,800. Default is ISO 800.
FLUT: FLUT (Floating Point Lookup Table) adjusts mid-range tone values. Range -8.0 to +8.0. Default is 0.0.
Shadow: Adjusts the toe value of the FLUT, or in other words, the tone near Black. Range is -2.0 to +2.0.
Default is 0.0. Increasing the Shadow value raises the video level of near Blacks. Lowering the Shadow
value crushes the video level of near Blacks.
CURVES
You can define the curves for the Luma, Red, Green, and Blue channels.
Select Reset Curve to reset the currently selected curve.
COLOR/GAMMA
You can adjust the monitor output Color Space and Gamma curves. RED recommends using the most recently
released Color Space and Gamma settings, and use legacy settings (such as REDcolor2) only if you need to
record footage to match footage that you recorded with that legacy setting.
For more information about RED gamma settings, check out the Understanding REDlogFilm and REDgamma
article available at www.red.com/learn/red-101/redlogfilm-redgamma.
COLOR TEMPERATURE
Color temperature range is 1700–100,000 K, with a default of 5600 K.
TINT
Color temperature calculations assume a pure light source that may not be true in the specific scene the cam-
era is imaging. To compensate for any residual colorcast, the Tint parameter adjusts the RGB color balance
with a compensating magenta-green color component. Tint range is -100 to +100, with a default of 0.000.
NOTE: Selecting Auto White Balance calculates a new Tint value. This value doesn’t change if you adjust the
color temperature manually. If you select any preset, Tint will be reset to 0.000.
PRESETS
Each preset has 0 Tint. Available preset options are:
Incandescent: 2800 K
Tungsten: 3200 K
Fluorescent: 4500 K
Flash: 5500 K
Daylight: 5600 K
Cloudy: 7500 K
Shade: 9000 K
AUTO WHITE BALANCE
The auto white balance function analyzes the central 25% of the image visible in the monitor to calculate a color
temperature that will render a white object as white.
To use the auto white balance function, follow the instructions below:
1. Place a white or gray object under the ambient light.
2. Select Auto White Balance.
