EXPOSURE

Select the exposure (shutter speed) of each frame. You can change exposure while recording.
Decreasing shutter speed increases the amount of time that light hits the sensor, which increases exposure and

motion blur of moving objects. Increasing shutter speed decreases the amount of time that light hits the sensor,

which decreases exposure and motion blur of moving objects.
The Upper Status Row displays the exposure as either shutter speed or shutter angle. For more information,

go to

“Exposure” on page 64

If the camera is able to achieve the target exposure, the exposure value displays in white. If the camera is

unable to achieve the target exposure, the exposure value displays in yellow, and the camera uses the closest

available exposure.
NOTE: If using speed ramp mode, select an exposure that is valid for each ramp target frame rate. If the camera

ramps to a frame rate that is incompatible with the current exposure, the exposure changes to the longest

exposure possible for the frame rate. For more information, go to

“Speed Ramp Mode” on page 94

EXPOSURE (SHUTTER SPEED)

Enter the exposure value as a shutter speed (1/xx sec).

MYSTERIUM-X: Slowest speed is 1/sensor frame rate. For 24 FPS, the slowest speed is 1/24 sec.

RED DRAGON: Slowest speed is 1/8 sec, regardless of the sensor frame rate.

The fastest speed is 1/131,579 sec. Default is 1/48 sec.

INTEGRATION TIME

Enter the exposure value as a shutter integration time (xx msec). The available integration times depend on the

sensor frame rate.

MYSTERIUM-X: Slowest speed is 1000 msec (1/1 sec).

RED DRAGON: Slowest speed is 125.109 msec (1/8 sec).

Default is 20.833 msec.

ANGLE (SHUTTER ANGLE)

Enter the exposure value as a shutter angle (xx°). Range is 1.000–360.000°. Default is 180.000°.

CONVERT SHUTTER SPEED TO SHUTTER ANGLE
Shutter Angle = (Shutter Speed x Frame Rate x 360)
Example: (1/48 x 24 x 360) = 180

CONVERT SHUTTER ANGLE TO SHUTTER SPEED
Shutter Speed = 1/(Frame Rate x 360/Angle)
Example: 1/(24 x 360/180) = 1/48
