This toolbar allows the current device's brightness, contrast and exposure properties to be adjusted.
The brightness level may be adjusted with this property. Increasing the brightness adds a constant value to all pixels.
The contrast of the image may be increased or decreased with this property.
Depending upon the setting of Swap Gain & Contrast, the controls for contrast may be in the Gamma & Sharpness Bar, and the controls for gain are found here.
This property is provided by cameras only. The exposure value specifies the period of time the imaging device of the camera is sensitive (like the shutter of a photo camera).
