From the EXPOSURE menu, you can control how the camera reacts to lighting

conditions.

SHUTTER: This setting controls the behaviour of the electronic shutter. In a

nutshell, it controls how long the camera will expose each frame. The longer that

the electronic shutter is “open”, the more light it will let in.

We recommend leaving this on AUTO (this will adjust the shutter speed

automatically). Only on rare occasions will AUTO not prove the best option -

however, these are so infrequent as to be almost unmentionable.

BRIGHTNESS: How light/dark the images coming from the camera will be. Unlike

the SHUTTER setting, this won’t affect how much light the camera needs to see to

create a high quality image. Rather, it affects how the camera processes the images

once they’ve been captured.

Increasing the BRIGHTNESS setting can be useful if you have an unusually dark

monitor/television, or are trying to view images in a very bright environment.

Typically, the default value is ﬁne unless you have speciﬁc problems you’re trying

to overcome.

AGC (Automatic Gain Control): Gain is a fancy term for amplifying a video

signal. It works in a similar way to amplifying music – the higher the gain, the

louder/brighter your images will be, but so will the background “noise” (in video

terms, “noise” refers to the random, grainy speckles that appear in images).

When should you decrease/increase the gain? Well, probably never. The MIDDLE

gain control is reliable and quite accurate. Only in the event of extremely unusual

lighting conditions or a very non-standard monitor/television should the automatic

gain control be adjusted.
