Final answer:
The photographic examination method historically used photographic film or sensitized paper with light-sensitive silver compounds that when exposed to light and developed, produced a lasting image.
Step-by-step explanation:
The photographic examination method uses photographic film or sensitized paper. This involves a historic process where a light-sensitive chemical coating, typically comprised of silver compounds, is applied to a substrate such as glass or film. When exposed to light and developed, this coating produces a lasting record of an image. Early photographic techniques such as the collodion process required this emulsion to be wet during exposure, necessitating portable darkrooms for field use. Over time, advancements in photography have given rise to more efficient and convenient methods, with modern digital sensors now largely supplanting traditional film and paper.
