The largest possible angle of incidence which still results in a refracted ray is called the critical angle; in this case the refracted ray travels along the boundary between the two media. Refraction of light at the interface between two media. For example, consider a ray of light moving from water to air with an angle of incidence of 50°.
When dealing with a beam that is nearly parallel to a surface, it is sometimes more useful to refer to the angle between the beam and the surface tangent, rather than that between the beam and the surface normal. The 90-degree complement to the angle of incidence is called the grazing angle or glancing angle. Incidence at small grazing angles ...

The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. [1] Adams described the Zone System as "[...] not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40."
Lev Vladimirovich Kuleshov (Russian: Лев Владимирович Кулешов; 13 January [O.S. 1 January] 1899 – 29 March 1970) was a Russian and Soviet filmmaker and film theorist, one of the founders of the world's first film school, the Moscow Film School. [1] He was given the title People's Artist of the RSFSR in 1969.
In film, an insert is a shot of part of a scene as filmed from a different angle and/or focal length from the master shot. Inserts cover action already covered in the master shot, but emphasize a different aspect of that action due to the different framing. An insert differs from a cutaway as cutaways cover action not covered in the master shot.
The imaginary line allows viewers to orient themselves with the position and direction of action in a scene. If a shot following an earlier shot in a sequence is located on the opposite side of the 180-degree line, then it is called a "reverse cut".
Formalist film theory is an approach to film theory that is focused on the formal or technical elements of a film: i.e., the lighting, scoring, sound and set design, use of color, shot composition, and editing. This approach was proposed by Hugo Münsterberg, Rudolf Arnheim, Sergei Eisenstein, and Béla Balázs. [1]
