TEST SIGNAL

Use the Test Signal menu to replace the video monitor outputs with one of the following video test patterns:

 Chip Chart

 SMPTE Bars

 Luma

To enable a test signal, select the test signal box. To exit, tap the touchscreen or press the Enter or Menu

button. If needed, enable an Audio Tone.

NOTE: Test signals are not recordable; they are provided to help align external HD-SDI and HDMI monitors.

LOOK

The Look menu includes: Color, Gain, ISO/FLUT, Sharpness, Curves, Video, Color Temperature, and LGG (Lift,

Gamma, Gain).

The Look settings affect the look of the monitor path, but do not affect the recorded RAW data.

COLOR

 Saturation: Adjusts color saturation. Range is 0.0 (monochrome) to 4.0 (super color). Default is 1.0.

 Contrast: Adjusts the overall contrast of the image. Range is –1.0 (flat) to 1.0 (max contrast). Default is 0.0.

 Brightness: Adjusts brightness without crushing highlights. Available range is –10.0 to 10.0. Default is 0.0.

 Exp Comp: Adjusts exposure compensation. Available range is –7.0 to 7.0. Default is 0.0.

GAIN

Adjust the Red channel, Blue channel, and Green channel individually. The range for each is 0.0 (none of the

color) to 10.0, and the default for each is 1.0.

ISO/FLUT

Use the ISO/FLUT menu to adjust ISO, FLUT, and Shadow. For more information, see the following articles:

 Exposure with RED Cameras: Strategy, available at www.red.com/learn/red-101/exposure-with-red-

cameras

 ISO Speed Revisited, available at www.red.com/learn/red-101/iso-speed-revisited

ISO

Select the camera ISO rating. The sensitivity value increments in 1/3 stops. When the ISO rating is adjusted,

the camera logs the change as metadata and the monitor path reacts accordingly. Higher ISO values lead to

brighter images in the monitor path, and vice versa.

RED recommends setting the ISO to the default, then adjust the aperture, lighting, and ND filters to match. The

ISO can later be adjusted around one (1) stop for fine-tuning.

Range is ISO 250 to 12,800. Default is ISO 800.

FLUT

Floating Point Lookup Table (FLUT) is an exposure control exclusive to RED. FLUT works like a traditional

ISO setting, but can be fine-tuned in post production to any level of exposure precision. FLUT automatically

protects highlights and shadows, even when changed substantially.

The FLUT setting is expressed in terms of relative exposure value (EV), where each unit represents a 1-stop

change in midtone exposure level. Range is –8.0 to 8.0. Default is 0.0.
