if you’re setting your camera on a tripod‚ at very slow shutter speeds (of half a second or more‚ such as one would use at night)‚ you might see some blur because of camera shake. Diaphragm (Apperture) The diaphragm or what we used to know as aperture is also plays significant part of the result on your pictures‚ the smaller the lens diaphragm the better‚ because it takes sharper image and better lightning quality. E.g a lens with 1.4 Diaphragm produce better picture than standard lens or lens

Important Personalities in Police Photography *Joseph Nicephore Niepce - was able to obtain camera images on papers sensitized with silver chloride solution in 1816.He invented a photographic process which he called "heliography" meaning "writing of the sun" *Louis Jacques Mande Daguerre - invented "Daguerreotype"‚ an early photograph produced on a silver or silver-covered copper plate.It formed an image directly on the silver surface of a metal plate.It was a positive process‚thus‚it yielded

DIGITAL TRANSMISSION Definition: Transmittal of digital signals between two or more points in a communications system. Advantages of Digital Transmission • Noise immunity • Ease of processing and combining • Ease of measuring and evaluating • Disadvantages of Digital Transmission • Requires more bandwidth • Necessitates encoding and decoding circuitry • Requires precise time synchronization • Incompatible with older analog transmission systems Pulse Modulation Pulse Modulation

1/Nastic Movement: "Nastic movements are non-directional responses to stimuli (e.g. temperature‚ humidity‚ light irradiance). The movement can be due to changes in turgor or changes in growth. Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus‚ whereas the direction of nastic movements is independent of the stimulus. The rate or frequency of these responses increases as intensity of the stimulus increases. An example of

How the Predator UAV Works Military commanders use tactics and strategy in combat to inflict as much damage on the enemy while trying to risk as few personnel and resources as possible. This principle was at the heart of the development of the RQ-1 and MQ-1Predator Unmanned Aerial Vehicle. These high-tech aircraft‚ controlled by a crew miles away from the dangers of combat‚ are capable of reconnaissance‚ combat and support roles in the hairiest of battles. In a worst-case scenario‚ if a Predator
