EXP COMP AND EV SHIFT
Use the
Exp Comp
(Exposure Compensation) slider and the
EV Shift
setting to adjust the brightness of the image.
The default setting of zero (0) attempts to match the average brightness on an 18% grey-target. When AE is
enabled, the target and current measured brightness for the selected metering area display in the histogram as
a grey 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.
METERING MODE
Metering determines the area of the sensor that is used for brightness evaluation:
Spot
: Weights the measurement to the center 5% of the sensor, approximately.
Center
: Weights the measurement to the center 25% of the sensor, approximately.
Average
: Averages the entire image area of the sensor.
SPEED
The Speed setting determines how quickly the algorithm adapts to changing light.
Slow
: Settings adapt in small steps. Use this setting for fewer and gradual adjustments.
Normal
: Settings adapt in medium steps.
Fast
: Settings adapt in large steps.
SELECTION
The Selection setting determines which values the algorithm uses. This enables you to modify the list of values
so that the algorithm selects only specific parameters. Use
Free Value Selection
to improve accuracy.
For example, you can modify the aperture list to include f/2.8 and f/5.6. If Free Value Selection is enabled, the
algorithm only selects aperture parameters between f/2.8 and f/5.6. This setting limits the range of focal depth.
AE INDICATORS
When the AE feature is able to match the sensor brightness, the overlay turns yellow. If the brightness fluctuates
more than half of a stop, the overlay turns red.
When AE is enabled, the “AE” indicator displays before the aperture and exposure parameters in the Upper
Status Row. The user-selected brightness and current measured brightness display in the histogram as grey
and white lines, respectively.
AE LIMITS
All limits, includes custom modifications made to available menu items, are taken into account when AE is
active. For example, if you modify the available list of exposure values, only those values are considered.
