Halation
A landmark scientific study on halation photography and cinematography by Dr. V. B. Sease (DuPont, 1931). This article from American Cinematographer explains what halation is, what causes it — scattered light reflecting off the back of film or glass plates — and traces the complete history of anti-halation techniques from early collodion plate backings to modern double-coated emulsions. Essential reading for anyone studying the physics of film emulsions.
