Viewfinder

In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of different types: still and movie, film, analog and digital. A zoom camera usually zooms its finder in sync with its lens, one exception being rangefinder cameras.

History

Before the development of microelectronics and electronic display devices, only optical viewfinders existed.

Direct optical viewfinders

Direct viewfinders are essentially miniature Galilean telescopes; the viewer's eye was placed at the back, and the scene viewed through the viewfinder optics. A declining minority of point and shoot cameras use them. Parallax error results from the viewfinder being offset from the lens axis, to point above and usually to one side of the lens. The error varies with distance, being negligible for distant scenes, and very large for close-ups. Viewfinders often show lines to indicate the edge of the region which would be included in the photograph.

Viewfinder (short story)

Viewfinder by Raymond Carver is one of the short stories in the What We Talk About When We Talk About Love compilation. It is told in the first person perspective of a man who is visited by an elderly man with hook hands. The man comes to his house to try and sell him a picture of the narrator's house. The narrator is obsessed with the fact that the elderly man has hook hands and invites him into his house to see how he will hold a cup of coffee with his hook hands. The narrator decides to have the hookhanded man take more pictures in his house. The story ends with the narrator climbing onto the roof so that his picture could be taken as he throws a rock off the roof.

Indicative of Carver's often dissociative and working class themes, the story focuses on the connection between physical and social deformity, the hook arms a shadow of the narrator's anti-social behavior.
