Exposure (magic)

Exposure in magic refers to the practice of revealing the methods of magic tricks.

The practice is generally frowned upon amongst magicians, who believe that it ruins the experience of magical performances for audiences.

Exposure is uniquely impactful to magicians, as magic relies heavily on the elusive nature of secrets and methods in order to create mystery.

Background

Magic effects have been exposed by both professional and amateur magicians. Some magic effects have been exposed in stage shows, and in other public media including television, the Internet, certain video sharing interfaces, discussion forums, and blogs.

One notable case of exposure on network television involved Val Valentino, performing as the "Masked Magician" in the Fox series Breaking the Magician's Code: Magic's Biggest Secrets Finally Revealed, which ran between 1997 and 1998. Valentino was ostracized by the magic community and received much criticism from magicians for contravening the joint International Brotherhood of Magicians and Society of American Magicians ethics statement.

Exposure (heights)

Exposure is a climbing and hiking term. Sections of a hiking path or climbing route are described as "exposed" if there is a high risk of injury in the event of a fall because of the steepness of the terrain. If such routes are negotiated without any protection, a false step can result in a serious fall. The negotiation of such routes can cause fear of falling because of the potential danger.

Definitions

What constitutes exposure on a path is fairly obvious, however, an "exposed" location or section of a climbing route is not uniformly or clearly defined in the literature. There are no threshold values, for example, based on the gradient of the terrain, the height of rock faces or the character of an ridge or arête. Authors tend to use their own definition of the terms "exposure" or "exposed" when describing routes, for example:

Exposure (photography)

In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.

In photographic jargon, an exposure generally refers to a single shutter cycle. For example: a long exposure refers to a single, protracted shutter cycle to capture enough low-intensity light, whereas a multiple exposure involves a series of relatively brief shutter cycles; effectively layering a series of photographs in one image. For the same film speed, the accumulated photometric exposure (H_v) should be similar in both cases.

Underexposure and overexposure

A photograph may be described as overexposed when it has a loss of highlight detail, that is, when important bright parts of an image are "washed out" or effectively all white, known as "blown-out highlights" or "clipped whites". A photograph may be described as underexposed when it has a loss of shadow detail, that is, when important dark areas are "muddy" or indistinguishable from black, known as "blocked-up shadows" (or sometimes "crushed shadows", "crushed blacks", or "clipped blacks", especially in video). As the image to the right shows, these terms are technical ones. There are three types of settings they are manual, automatic and exposure compensation.

Exposure (UK TV series)

Exposure is a current affairs strand, broadcast in the United Kingdom on the ITV network. The programme comprises long-form films, investigating and exploring domestic and foreign topics. Episodes are produced both by independent production companies and in-house by ITV Studios. The average budget for a single edition is between £150,000 and £200,000.

The series was commissioned by Peter Fincham, ITV's Director of Television, and is a sister show to year-round current affairs strand Tonight. It made its debut on Monday 26 September 2011 – airing at 22.40, directly after ITV News at Ten. Since its launch, the programme has usually occupied this near-peak slot, but has also been shown as late as 23.10. On 3 March 2015, it made its only appearance to date in primetime, airing at 21.00.

The series was broadcast on Mondays in 2011 and Wednesdays in 2012. The 2013 series was billed as an eight-episode run (the longest to date), with five of the editions airing on consecutive Thursdays in their traditional autumn slots and the remaining three being broadcast as standalone episodes between February and July 2014.

Exposure (U.S. TV series)

Exposure is a short-film oriented science-fiction anthology series that aired on the Sci-Fi Channel between the years of 2000 and 2002. The series showcased the short sci-fi films of both unknown and known (Tim Burton, George Lucas and Kevin Smith) filmmakers, giving rise to the channel's own Exposure Studios. Hosted by actress Lisa Marie, the films presented a wide range of science fiction subject matter. The series received poor ratings and was canceled in the fall of 2002. The series was originally shown on Sundays at 10:00pm EST and was repeated the following Saturday at 2:00am EST, later on the time was changed to 11:00pm EST and still repeated the following Saturday well after Midnight, which probably is a major reason for the poor ratings this show received. The series also had two guest hosts. Terry Farrell (Star Trek: Deep Space Nine) would host the "Best of Season One" episode and director Kevin Smith hosted the "Star Wars Short Films Showcase".

The Sci-Fi Channel had also struck a deal with AtomFilms which gave them the broadcast rights of any of Atom Films' new science-fiction acquisitions, as well as all science fiction films currently in their library, for Exposure.
