Based on the description given, what is not shown in this "fly on the wall" mode is any interaction between the filmmaker and the subject being filmed. The filmmaker is not providing any commentary or direction, and the camera is simply recording what is happening without any editing or manipulation of the footage.
Framing, angle, and lighting can all have a significant impact on our perceptions of the subject being filmed. For example, a close-up shot can make the subject feel more intimate and personal, while a wide shot can create a sense of distance and detachment. The angle of the shot can also influence how we perceive the subject, with low angles making the subject appear more powerful or dominant, and high angles making them appear weaker or more vulnerable. Lighting can also be used to create different moods or atmospheres, with bright lighting creating a sense of energy and excitement, and dark lighting creating a more somber or ominous mood.
