HISTOGRAM
This section describes the elements that comprise the Histogram section in the Lower Status Row. This section
of the GUI helps ensure that recorded footage is properly exposed.
Tap the Histogram in the Lower Status Row to access the Tools menu. For more information, go to
“Tools” on
page 58 .

# HISTOGRAM ITEMS DESCRIPTION
1 RAW Level Bar (left)
1
Also known as a “goal post”. Displays the amount of pixels in the image
that are underexposed (noise)
2 RGB Histogram Provides a visual representation of exposure and sensor data levels for
Red, Green, and Blue channels; meter is affected by White Balance, ISO,
and VIEW/LOOK settings
3 RAW Level Bar (right)
1
Also known as a “goal post”. Displays the amount of pixels in the image
that are overexposed (clipping)
4 RAW Clip Meter Also known as “traffic lights”. Displays RGB sensor RAW clipping status
1. The RAW Level Bars display the amount of pixels in the image that are noisy or clipped in relation to the total number of pixels in the
image. For example, if the left RAW Level Bar is 1/8 of the total height, that means that approximately 1/8 of the total pixels in the total
image are at an exposure level that is at risk of displaying noise when pushed to higher ISO or FLUT values in post-production.
SYSTEM STATUS INDICATORS
This section describes the colors and behavior of the System Status indicators in the Lower Status Row. Tap
the System Status indicators in the Lower Status Row to access the System Status menu. For more information,
go to “System Status” on page 108 .
CAL: T/E INDICATOR
The CAL: T/E indicator shows changes to temperature (T) or exposure (E) in relation to the active calibration
map. If the temperature or exposure change significantly, black shade the camera at the desired temperature
and exposure. Failure to properly calibrate the sensor may reduce image quality.
Green : Sensor temperature or exposure are properly calibrated for current settings.
Yellow : Slight change in sensor temperature or exposure.
Red : Significant change in sensor temperature or exposure.
The – and + indicate whether the sensor temperature or exposure has decreased or increased, respectively.
NOTE: T and E indicators change colors independently of each other.
TC INDICATOR
The TC indicator shows the current timecode status.
Gray : No analog time code is detected.
Red : Analog timecode is detected but not enabled.
Green : Analog timecode is used to jam the time of day time code.
For more information, go to “Timecode, Genlock, Multi-Camera Setup” on page 143 .
