Digital Camera Backs
A digital camera back is a device that attaches to the back of a camera in place of the traditional Negative (photography), negative film holder and contains an electronics, electronic image sensor. This allows cameras that were designed to use photographic film, film take digital photography, digital photographs. These camera backs are generally expensive by consumer standards (US$5,000 and up) and are primarily built to be attached on Medium format (film), medium- and large format, large-format cameras used by Photography#Commercial, professional photographers. Types Two sensor back types are commonly used: single shot back (non-scanning) and scan back. Some backs, primarily older ones, require multiple exposures to capture an image; generally one each for red, green, and blue. These are called multi-shot or 3-shot backs. As technology advanced single-shot backs became more practical; by 2008 most backs manufactured were single-shot. Early backs had to be used tethered by a c ...

Sensor IMG 2924
A sensor is often defined as a device that receives and responds to a signal or stimulus. The stimulus is the quantity, property, or condition that is sensed and converted into electrical signal. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into Attitude and heading reference system, MARG sensors. Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
