ers at one go, click the Default button. To reset one of them, double-click its value at

Tuning Light in the Image
To tune illumination, install a lens (see “Installing Lens” on page 26 ).
To tune light in the image:
1 Use maximum diaphragm aperture of your lens.
2 Try to get enough light using the Exposure slider.
3 If the Exposure slider is at maximum and more light is needed, decrease frequency
(it will enlarge the exposure interval).
4 If illumination is not enough, use the Gain group of sliders (All, R, G, B).
5 Press e on the keyboard to adjust the exposure automatically.

image becomes as bright as you need.
