Aperture
Some camera bodies allow you to adjust the aperture from your computer.
If you are using one of these bodies, then the Aperture setting controls
your camera body. For other camera bodies, this setting will be inactive
(grey).
Adjusting Light and Contrast
By default the Light and Contrast settings are done automatically, but
unchecking the Auto box will enable you to adjust these parameters
manually.
