Tip Using IPods or Digital Cameras To Store Your Data

View Camera ... The bellows is a flexible, accordion-pleated box, which encloses the space between the lens and film, and has the ability to flex to accommodate the movements of the standards. The front standard is a board at the front of the camera which holds the lens and, usually, a shutter...

Camera ... Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum... A majority of cameras have a lens positioned in front of the camera's opening to gather the incoming light and focus all or part of the image on the recording surface... The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture...

Single-lens Reflex Camera ... Prior to the development of SLR, all cameras with viewfinders had two optical light paths: one path through the lens to the film, and another path positioned above (TLR or twin-lens reflex) or to the side (rangefinder)... Most SLR cameras permit upright and laterally correct viewing through use of a roof pentaprism situated in the optical path between the reflex mirror and viewfinder...

Photography ... Digital cameras use an electronic image sensor based on light-sensitive electronics such as charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) technology...

History Of Photography ... Ibn al-Haytham (Alhazen) (965–1040) studied the camera obscura and pinhole camera, Albertus Magnus (1193/1206–80) discovered silver nitrate, and Georges Fabricius (1516–71) discovered silver chloride. Daniel Barbaro described a diaphragm in 1568...

International Space Station ... The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars...

Mobile Phone Features ... The common components found on all phones are: A battery, providing the power source for the phone functions. An input mechanism to allow the user to interact with the phone...

Fisheye Lens ... For digital cameras using smaller electronic imagers such as 1/4" and 1/3" format CCD or CMOS sensors, the focal length of "miniature" fisheye lenses can be as short as 1 to 2mm...

Box Camera ... Etienne Carjat (1828–1906) another French photographer created "le Phobus'" around the late 1870s. It was a simple mahogany box camera...

Shutter (photography) ... Other mechanisms than the dilating aperture and the sliding curtains have been used; anything which exposes the film to light (for a specified time) will suffice. The time for which a shutter remains open (exposure time) is determined by a timing mechanism...

Optics ... Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice...

Film Crew ... Crew are distinguished from cast, the actors who appear in front of the camera or provide voices for characters in the film. Crew are also separate from producers, those who own a portion of either the film company or the film's intellectual property rights...

Full-spectrum Photography ... Modified digital cameras can detect some ultraviolet, all of the visible and much of the near infrared spectrum, as most digital imaging sensors are sensitive from about 350nm to 1000nm...

Angénieux Retrofocus ... The telephoto lens configuration combines positive and negative lens groups with the positive at the front, so as to reduce the back focal distance of the lens (the distance between the back of the lens and the image plane) to a figure shorter than the focal length. This is for practical, not optical reasons, because telephotos can then be made shorter and less cumbersome...

Folding Camera ... Folding cameras were dominant from the beginning of the 20th century to WWII, and medium format folders were produced in USSR until the 1960s... The use of folding cameras began to decline after WWII with the development of the 35mm film format, which allowed the construction of small-sized cameras without use of a bellows...

Independent Film ... Because of this, a number of filmmakers responded by building their own cameras and moving their operations to Hollywood, California, where the distance from Edison's home base of New Jersey made it more difficult for the MPPC to enforce its patents...
