Polaroid Impulse
The Polaroid Impulse is a camera produced by Polaroid Corporation between 1988 and 1994. The camera uses Polaroid's 600-series integral film. The Impulse is distinguished from Polaroid's other 600-series cameras by its always-on flash, binocular-style grips, larger viewfinder, and self-timer (autofocus models only). Models The Polaroid Impulse was manufactured with two different lens configurations. The first featured a fixed-focus lens (sometimes paired with a secondary close-up lens), while the second featured Polaroid's sonar autofocus system. Both configurations were released under a variety of names in gray, black, yellow, blue, green, and magenta colorways. *Some versions of the Impulse AF include a remote control port, compatible with the Polaroid Spectra System Remote Control.''''

Polaroid Corporation
Polaroid is an American company best known for its instant film and cameras. The company was founded in 1937 by Edwin H. Land, to exploit the use of its Polaroid polarizing polymer. Land ran the company until 1981. Its peak employment was 21,000 in 1978, and its peak revenue was $3 billion in 1991. When the original Polaroid Corporation was declared bankrupt in 2001, its brand and assets were sold off. The "new" Polaroid formed as a result, itself declared bankruptcy in 2008, resulting in a further sale to Polish billionaire Wiaczesław Smołokowski. In May 2017, the brand and intellectual property of Polaroid Corporation were acquired by the largest shareholder of the Impossible Project, which had originally started out in 2008 by producing new instant films for Polaroid cameras. The Impossible Project was renamed Polaroid Originals in September 2017, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polaroid SX-70
The SX-70 is a folding single lens reflex Land camera which was produced by the Polaroid Corporation from 1972 to 1981. History In 1948, Polaroid introduced its first consumer camera. The Land Camera Model 95 was the first camera to use instant film to quickly produce photographs without developing them in a laboratory. The popular Model 95 and subsequent Land Cameras required complex procedures to take and produce good photographs. Photographic paper had to be manually removed from cameras, peeled open after 60 seconds, needed several minutes to dry, and often left developing chemicals on hands. The instructions for the Model 20 Swinger, introduced in 1965, warned that, if not followed, "you’re headed for plenty of picture taking trouble". Pictures from the SX-70, by contrast, ejected automatically and developed quickly (fully within 10 minutes) without chemical residue. Polaroid founder Edwin H. Land announced the SX-70 at a company annual meeting in April 1972. On s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instant Film
Instant film is a type of photographic film that was introduced by Polaroid Corporation to produce a visible image within minutes or seconds of the photograph's exposure. The film contains the chemicals needed for developing and fixing the photograph, and the camera exposes and initiates the developing process after a photo has been taken. In earlier Polaroid instant cameras the film is pulled through rollers, breaking open a pod containing a reagent that is spread between the exposed negative and receiving positive sheet. This film sandwich develops for some time after which the positive sheet is peeled away from the negative to reveal the developed photo. In 1972, Polaroid introduced ''integral film'', which incorporated timing and receiving layers to automatically develop and fix the photo without any intervention from the photographer. Instant film has been available in sizes from (similar to 135 film) up to size, with the most popular film sizes for consumer snapshots be ...

Autofocus
An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers.

Fixed-focus Lens
A photographic lens for which the focus is not adjustable is called a fixed-focus lens or sometimes focus-free. The focus is set at the time of lens design, and remains fixed. It is usually set to the hyperfocal distance, so that the depth of field ranges all the way down from half that distance to infinity, which is acceptable for most cameras used for capturing images of humans or objects larger than a meter. Rather than having a method of determining the correct focusing distance and setting the lens to that focal point, a fixed-focus lens relies on sufficient depth of field to produce acceptably sharp images. Most cameras with focus-free lenses also have a relatively small aperture, which increases the depth of field. Fixed-focus cameras with extended depth of field (EDOF) sometimes are known as full-focus cameras. Concept In order to reach a minimal focal distance, the aperture and the focal length of the lens are reduced (a slow wide-angle lens), to make the hyperfocal d ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...
