EXPOSURE ASSIST
The Exposure Assist menu provides access to settings for the Auto Exposure (AE) feature. The AE feature
maintains a constant image brightness, even if the actual scene brightness changes.
The AE feature is different than traditional AE, in that RED AE only controls the amount of light that hits the
sensor, either by adjusting F stop or exposure. RED AE analyzes RAW data before the ISO curve, and ensures
that the sensor matches the user-selected brightness.
AUTO EXPOSURE MODES
SINGLE SHOT EXPOSURE
In Singe Shot mode, you can trigger an exposure adjustment manually. The camera attempts to meet the
selected brightness by adjusting the F stop and exposure. Map the AE:Recalc action to the desired key to
trigger the exposure calculation.
CONTINUOUS IN PREVIEW
When in Continuous in Preview mode, the camera continuously adjusts F stop and exposure to meet the user-
selected brightness. The auto exposure adjustments are only made in preview modes.
CONTINUOUS IN PREVIEW/RECORD
When in Continuous in Preview/Record mode, the camera continuously adjusts F stop and exposure to meet
the user-selected brightness. The auto exposure adjustments are applied in preview and record modes.
AUTO EXPOSURE SETTINGS
EV SHIFT
EV shift adjusts the brightness of the image. The default setting of zero (0) attempts to match the average
brightness on an 18% gray-target. When AE is enabled, the target and current measured brightness for the
selected metering area display in the histogram as a gray and white line, respectively.
You can also map these actions to user keys:
AE: Decrease EV Offset: Reduces the EV Offset in increments of 0.2.
AE: Increase EV Offset: Increases the EV Offset in increments of 0.2.
