When planning for your next video shoot, and before considering buying another microphone for your
camera, you should become familiar with the two types of microphones: directional and nondirectional.
The directional microphone records sounds from a specific direction while eliminating most of the
background noise. This type of microphone records sound traveling from only one
direction. It is best to aim this type of microphone in the direction of the sound’s source. You will also
need to adjust your boom arm so that the position of the directional microphone is such that it’s pick up is clear and in keeping with the perspective of the scene.
The closer the microphone is to the sound’s source, the louder the sound will be heard in relation to extraneous noise, so you should maintain a perspective of the picture. We cannot shoot a long shot and
have the dialogue sound as if it were right beside us, nor can we have close-up sound when the
scene is a long shot.
Extremely loud sounds, particularly those with a sudden impact like a balloon popping or a child screaming should be recorded at a different level from your subject’s speaking voice. Therefore, during editing, you could combine the extremely loud sounds with your recordings and secure an overall effect which will sound normal to the human ear.
You probably already figured it out, Non directional microphones will pick up all the sounds and noises around it.
