Types of Camera Shots

Medium shot:

In film, a medium shot is a camera angle shot from a medium distance. The dividing line between "long shot" and "medium shot" is fuzzy, as is the line between "medium shot" and "close-up". In some standard texts and professional references, a full-length view of a human subject is called a medium shot; in this terminology, a shot of the person from the knees up or the waist up is a close-up shot. In other texts, these partial views are called medium shots. (For example, in Europe a medium shot is framed from the waist up). It is mainly used for a scene when you can see what kind of expressions they are using

Long shot:

In photography, film making and video production, a Long Shot (sometimes referred to as a Full  shot or a wide shot) shows the entire object or human figure and is usually intended to place it in some relation to its surroundings. It has been suggested that long-shot ranges usually correspond to approximately what would be the distance between the front row of the audience and the stage in live theatre. It is now common to refer to a long shot as a "wide shot" because it often requires the use of a wide-angle lens. When a long shot is used to set up a location and its participants in film and video, it is called an establishing shot.

Establishing Shot:

An establishing shot in film making and television production sets up, or establishes the context for a scene by showing the relationship between its important figures and objects. It is generally a long- or extreme-long shot at the beginning of a scene indicating where, and sometimes when, the remainder of the scene takes place (Setting)

Close up:

In filmmaking, television production, still photography and the comic strip medium a Close Up tightly frames a person or an object. Close-ups are one of the standard shots used regularly with medium shots and long shots. Close-ups display the most detail, but they do not include the broader scene. Moving in to a close-up or away from a close-up is a common type of zooming.
