When using an ordinary video camera all settings are automatic and nothing needs to be done manually, however, in order to improve your camera work, you must learn to take control of your camera and set all settings manually. In most cases auto-functions work very well, however, it may go in and out of focus, this affecting the quality of the shot you were looking for. Auto-focus gives an ameatur shot, in order to operate manually the camera should have a focus ring at the front. Turning the focus ring clockwise gives a closer focus and turning it anti-clockwise gives a more distant focus.
There are many other manual functions such as Zoom, Iris, White Balance, Audio, Shutter and Effects.
Zoom moves you closer or further away from your point of view. Zooming is easy to do, however, it works well in moderation.
Iris is an adjustable opening that controls the amount of light going in, this is known as exposure. Most professional cameras have an Iris Ring, which turning it anti-clockwise opens and lets more light in.
White Balance tells the camera what whit should look like in your shot, therefore balancing the other colours. This function is normally done automatically, however can this sometimes can make the colours in the shot look unnatural.
Audio is very important and should not be overlooked. Most cameras come with a built-in microphone which work fine for general work, however, external microphones can be used.
The Shutter is usually used for fast action footage. An advantage to the shutter is that it can make a shot sharper, however, the disadvantage being it can make a shot jerky.
Most cameras come with a range of effects, some can look brilliant or, if used too much, can look tacky. Again, they should be used in moderation.
