Gain To adjust the distance correctly there is a particular sequence of actions: first, the main object must be zoomed-in, then the focus ring of the lens must be used to sharpen the picture and only then should the image section be fixed to finally start the recording. When the actors are moving either towards or away from the camera, the distance consequently changes so the sharpness must be adjusted on an ongoing basis during the recording. The same needs to be done for movements of the camera. However, this is part of more highly developed camera work and thus is explained later in more detail. 43
