Photographic lens design
The design of photographic lenses for use in still or cine cameras is intended to produce a lens that yields the most acceptable rendition of the subject being photographed within a range of constraints that include cost, weight and materials. For many other optical devices such as telescopes, microscopes and theodolites where the visual image is observed but often not recorded the design can often be significantly simpler than is the case in a camera where every image is c…
Science of photography
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 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 …
Panoramic photography
Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with horizontally elongated fields of view. It is sometimes known as wide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in ...
Timeline of photography technology
1986 – Kodak scientists invent the world''s first megapixel sensor. 1987. Canon releases the first camera for its fully electronic autofocus EF lens mount, the EOS 650 [20] Photoshop developed by Thomas and John Knoll. 1990 — Adobe Photoshop 1.0 released on February 19, for Macintosh exclusively.
Zoom lens
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 ...
Polarizing filter (photography)
Polarizing filter (photography) Circular polarizer /linear analyzer [1] filtering unpolarized light and then circularly polarizing the result. A polarizing filter or polarising filter (see spelling differences) is a filter that is often placed in front of a camera lens in photography in order to darken skies, manage reflections, or suppress ...
Telecentric lens
Telecentric lens. A telecentric lens is a special optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity. The size of images produced by a telecentric lens is insensitive to either the distance between an object being imaged and the lens, or the distance between the image plane and the ...
Monochrome photography
Monochrome photography is photography where each position on an image can record and show a different amount of light, but not a different hue includes all forms of black-and-white photography, which produce images containing shades of neutral grey ranging from black to white. Other hues besides grey, such as sepia, cyan, blue, or brown can also be …
Lens (optics)
A lens is a clear ( transparent) object (like glass, plastic or even a drop of water) that changes the way things look by bending the light that goes through it. They may make things appear larger, smaller, or upside-down. Some places lenses are used include spectacles ( eyeglasses ), contact lenses, cameras, projectors, microscopes, telescopes ...
Double-Gauss lens
The earliest double Gauss lens, patented by Alvan Graham Clark in 1888, consists of two symmetrically-arranged Gauss lenses. Each Gauss lens is a two-element achromatic lens with a positive meniscus lens on the object side and a negative meniscus lens on the image side. In Clark''s symmetric arrangement, this makes four elements in four groups ...
Pinhole camera
A home-made pinhole camera lens. A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole )—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura ...
Bokeh
Coarse bokeh on a photo shot with an 85 mm lens and 70 mm entrance pupil diameter, which corresponds to f / 1.2 An example of a portrait photo (of Katherine Maher).Note the ''swirly'' bokeh. How the bokeh varies with the aperture. In photography, bokeh (/ ˈ b oʊ k ə / BOH-kə or / ˈ b oʊ k eɪ / BOH-kay; Japanese:) is the aesthetic quality of the blur …

Tilt–shift photography
Tilt-lens photo of a model train. Note how the focus plane is along the train, and how the blurring of the background proceeds from left to right. Tilt–shift photography is the use of camera movements that change the orientation or position of the lens with respect to the film or image sensor on cameras .
Flat lens
A flat lens is a lens whose flat shape allows it to provide distortion-free imaging, potentially with arbitrarily-large apertures. ... Traditional curved glass lenses can bend light coming from many angles to end up at the same focal point on a piece of photographic film or an electronic sensor. Light captured at the very edges of a curved ...

Periscope lens
Periscope lens. Schematic of a conventional and a periscope zoom lens. A smartphone with a 5x optical zoom periscope lens camera, recognizable by the rectangular shape of its lens. A periscope lens, sometimes called a folded lens, is a mechanical assembly of lens elements that uses a prism or mirror to redirect the light through the lenses with ...
