6. Using Auto Exposure
The camera’s exposure parameters can be controlled
manually or with auto exposure by adjusting the settings on
the camera’s LCD screen or with iX Capture.
Auto exposure controls the camera’s three exposure parameters:
• ISO
• Aperture
• Shutter speed
When auto exposure is activated, the camera reads the
histogram of each image after it is captured and adjusts the
exposure parameters for the next image. The adjustments are
in third stop increments.
To use Auto Exposure mode, do the following:
• Select Auto Exposure Range
• Select Auto Exposure Priority
• Activate Auto Exposure Mode
• Adjust Auto Exposure Bias (if needed)
The camera uses the following parameters for the first exposure:
• ISO — Value selected in Auto Exposure Minimum.
• Aperture — Average aperture between Auto Exposure
Minimum and Maximum.
• Shutter speed — Value set in Auto Exposure Maximum.
When using auto exposure, the camera uses the parameters
listed above for the first exposure. Capture a few images
before your first flight line in order for auto exposure to set
the optimum exposure.
When Auto Exposure mode is activated, the exposure
parameters (ISO, aperture and shutter speed) are grayed out.
If the camera has Auto Exposure mode and FMC activated,
Auto Exposure mode only controls ISO and aperture. The
shutter speed is controlled manually.
