A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically . There is no major difference in principle ...
For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus in the image. [ 1] ". Acceptably sharp focus" is defined using a property called the "circle of confusion". The depth of field can be determined by focal length ...
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens ( prime lens ). A true zoom lens or optical zoom lens is a type of parfocal lens, one that maintains focus when its focal length changes. [1] Most consumer zoom lenses do not maintain ...
However, they have been available for amateur motion picture, video and still cameras since the 1950s. [1]: 182–183 Before the zoom lens, afocal attachments were a way to provide a cheap sort of interchangeable lens system to an otherwise fixed lens camera. In the zoom lens era, they are a cheap way to extend the reach of a zoom.
Science of photography. The science of photography is the use of chemistry and physics in all aspects of photography. This applies to the camera, its lenses, physical operation of the camera, electronic camera internals, and the process of developing film in order to take and develop pictures properly. [1]
Macro photography. Macro photograph of a common yellow dung fly ( Scathophaga stercoraria) made using a lens at its maximum 1:1 reproduction ratio, and an 18×24mm image sensor, the on-screen display of the photograph results in a greater than life-size image. Headshot of a dragonfly taken with a 100 mm macro lens coupled with a 50 mm lens in ...
Film theory. Film theory is a set of scholarly approaches within the academic discipline of film or cinema studies that began in the 1920s by questioning the formal essential attributes of motion pictures; [ 1] and that now provides conceptual frameworks for understanding film 's relationship to reality, the other arts, individual viewers, and ...
Bokeh can be made with a combination of both lenses, and shots can be refocused even after they are captured, adding bokeh effects with different depths. [26] In early 2018, the Honor 9 Lite smartphone was released with quad cameras (two dual-lens). Both the front and back cameras have a 13 MP main lens and a 2 MP lens for capturing bokeh depth ...
