A lens where the focal length is approximately equal to the diagonal of the film size it's being used for. This is also representative of the field of view of human sight. In 35mm format it is approximately 50mm, in medium format approximately 90mm, in 4x5 approximately 250mm.
A lens that shows objects without severely exagger- ating or reducing the depth of the scene's planes. In 35mm filming, a normal lens is 35 to 50mm. See also telephoto lens, wide-angle lens.
A lens that shows objects without severely exaggerating or reducing the depth of the scene's planes. In theatrical filmmaking, a normal lens is 35mm to 50mm. See also telephoto lens, wide-angle lens.
a lens whose focal length is equal to the field of view of human beings
Pictures taken with a 50mm lens resembles human vision.
A lens with a focal length approximately the same as the diagonal measurement of the film being used. This produces an image that approximates the same angle of view and perspective of the human eye. For a 35mm camera, the 50mm lens is considered normal. OCR Acronym for Optical Character Recognition. It is a software that converts scanned text documents fron an image back into editable text Panning Moving the camera so that the image of a moving object remains in the same relative position in the viewfinder as you take a picture.
25mm lens (for 16mm cameras) and 50mm lens (for 35mm cameras).
This term designates lenses that have an angle of coverage of approximately 46 degrees, which corresponds to the perspective given by the human eye. In 35mm photography, lenses of focal length between 48 and 60 degrees fall in this category. However, due to the refraction phenomenon, a 35mm lens used underwater behind a flat port has an angle of 46 degrees and is dubbed "normal".
A lens that makes the image in a photograph appear in perspective similar to that of the original scene (approximately 45°). A normal lens has a shorter focal length and a wider field of view than a telephoto lens, and a longer focal length and narrower field of view than a wide-angle lens. Normal lenses corresponding to that portion of human vision in which we can discern sharp detail; technically defined as a lens whose focal length is approximately equal to the diagonal of the film frame; in 35mm photography, the diagonal measures 43mm, but in practice, lenses with focal lengths from 50mm to 60mm are considered normal.
A lens with a focal length of approximately the diagonal measurement of the film image area. A 50mm lens is considered the normal lens for 35mm photography. Normal lenses view the subject like unaided human eyes, neither reducing or enlarging the subject size.
A lens that accommodates an image of approximately the same angle of view and the same proportion as that of which the human eye is capable.
In photography and cinematography a normal lens is a lens that generates images that are generally held to have a "natural" perspective compared with lenses with longer or shorter focal lengths.
