Document Summary

Aberrations constitute the main problem of lens design. A method to correct this is stop down the lens, making it more like a pinhole. Coating of surfaces makes lens nearly transparent. Fish eye lenses produce extremely wide angle that you produce extreme examples of distortion. Anamorphic lenses gives a wide screen view with an undiscovered image. Shutter - device that controls exposure time. Stop action photograph object without getting streaks in the direction of motion. Fast refers to various different features that enable pictures to be taken in a short time. Focal plane shutters admit from the entire length about the exposure, whereas between the lens shutters cover up a portion of the lens during the opening and closing phases. Stop an opaque barrier with a hole. F-numbers = focal length of lens / diameter of stops hole.
