Question

what is the purpose of long shots film techniques

Answer 1

Explanation:

Long Shot (aka Wide Shot)  Shows the subject from top to bottom; for a person, this would be head to toes, though not necessarily filling the frame. The character becomes more of a focus than an Extreme Long Shot, but the shot tends to still be dominated by the scenery. This shot often sets the scene and our character’s place in it. This can also serve as an Establishing Shot, in lieu of an Extreme Long Shot.
