Ghost
A ghost is the soul or spirit of a dead person or animal that is believed to be able to appear to the living. In ghostlore, descriptions of ghosts vary widely from an invisible presence to translucent or barely visible wispy shapes, to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a ''séance''. Other terms associated with it are apparition, haunt, phantom, poltergeist, shade, specter or spectre, spirit, spook, wraith, demon, and ghoul. The belief in the existence of an afterlife, as well as manifestations of the spirits of the dead, is widespread, dating back to animism or ancestor worship in pre-literate cultures. Certain religious practices—funeral rites, exorcisms, and some practices of spiritualism and ritual magic—are specifically designed to rest the spirits of the dead. Ghosts are generally described as solitary, human-like essences, though stories of ghostly armies and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spirit Photography
Spirit photography (also called ghost photography) is a type of photography whose primary goal is to capture images of ghosts and other spiritual Non-physical entity, entities, especially in ghost hunting. It dates back to the late 19th century. The end of the American Civil War and the mid-19th Century Spiritualism movement contributed greatly to the popularity of spirit photography. Photographers such as William H. Mumler, William Mumler and William Hope (paranormal investigator), William Hope ran thriving businesses taking photos of people with their supposed dead relatives. Both were shown to be frauds, but "true believers", such as Arthur Conan Doyle, Sir Arthur Conan Doyle, refused to accept the evidence as proof of a hoax. As cameras became available to the general public, ghost photographs became common due to natural camera artifacts such as flash reflecting off dust particles, a camera strap or hair close to the lens, lens flare, pareidolia, or in modern times, deception ...

Afterimage
AfterImage is a Filipino rock band formed in 1986, best known for their songs "Habang May Buhay", "Next in Line", and "Mangarap Ka". They disbanded in 1997 and became active again in 2008 after they reunited and released their fourth studio album. After disbanding in 1997, Wency Cornejo, the band's vocalist, pursued a solo career. In January 1992, the band signed with Dyna Records, The band's first album, entitled ''Touch the Sun'', was released in July 1992. Among the eight songs that the album contained, four were released as singles: "Next in Line", "Bai (Sa Langit ang Ating Tagpuan)", "Only You", and "Pagtawid". The title of the album, which was the concluding part of the lyric to "Next in Line", was said to have just been a spontaneous utter of phrase which Cornejo made during the recording session for the said song. History The band was composed of five members: Bobit Uson on bass guitar, Chuck Isidro on lead guitar, Rogie Callejo on drums, Arnold Cabalza on keyboards and ...

Ghosting (television)
In television, a ghost is a replica of the transmitted image, offset in position, that is superimposed on top of the main image. It is often caused when a TV signal travels by two different paths to a receiving antenna, with a slight difference in timing.Jorma Hyypia, ''Beating TV Interference'', ''Popular Mechanics'' , June 1980 page 126 Analog ghosting Common causes of ghosts (in the more specific sense) are: * Mismatched impedance along the communication channel, which causes unwanted reflections. The technical term for this phenomenon is ringing. * Multipath distortion, because radio frequency waves may take paths of different length (by reflecting from buildings, transmission lines, aircraft, clouds, etc.) to reach the receiver. In addition, RF leaks may allow a signal to enter the set by a different path; this is most common in a large building such as a tower block or hotel where one TV antenna feeds many different rooms, each fitted with a TV aerial socket (kno ...

Image Persistence
Image persistence, or image retention, is the LCD and plasma display equivalent of screen burn-in. Unlike screen burn, the effects are usually temporary and often not visible without close inspection. Plasma displays experiencing severe image persistence can result in screen burn-in instead. Image persistence can occur as easily as having something remain unchanged on the screen in the same location for a duration of even 10 minutes, such as a web page or document. Minor cases of image persistence are generally only visible when looking at darker areas on the screen, and usually invisible to the eye during ordinary computer use. Cause Liquid crystals have a natural relaxed state. When a voltage is applied they rearrange themselves to block certain light waves. If left with the same voltage for an extended period of time (e.g. displaying a pointer or the Taskbar in one place, or showing a static picture for extended periods of time), the liquid crystals can develop a tendency t ...

Screen Burn-in
Screen burn-in, image burn-in, or ghost image, is a permanent discoloration of areas on an electronic display such as a cathode ray tube (CRT) in an old computer monitor or television set. It is caused by cumulative non-uniform use of the screen. Newer liquid-crystal displays (LCDs) may suffer from a phenomenon called image persistence instead, which is not permanent. One way to combat screen burn-in was the use of screensavers, which would move an image around to ensure that no one area of the screen remained illuminated for too long. Causes With phosphor-based electronic displays (for example CRT-type computer monitors, oscilloscope screens or plasma displays), non-uniform use of specific areas, such as prolonged display of non-moving images (text or graphics), repetitive contents in gaming graphics, or certain broadcasts with tickers and flags, can create a permanent ghost-like image of these objects or otherwise degrade image quality. This is because the phosphor compound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
