Under the Camera Controls tab, make the appropriate
adjustments from the menu list to fine tune the image
related parameters such as Brightness, Contrast,
Saturation, Sharpness, Hue, Backlight, and Exposure or set
to Default.
Brightness tells how much white or black that exists in
the image. It is the amount of light reflected in proportion
to the amount absorbed by the material in the image.
Therefore, reflective objects are bright, and vise versa.
Contrast is the degree of difference in tone between the
light and dark parts of an image. The higher the contrast
the brighter the image and the lower the contrast the
darker it will become.
Saturation is an expression for the relative bandwidth of
the visible output from a light source. As saturation
increases, colors appear more pure and as it decreases,
colors appear more washed out.
Sharpness determines how crisp the image quality looks.
For example, when sharpness is high, the picture will look
crisp and edges will be well-defined.
