Headlight flashing

Headlight flashing refers to the act of either briefly switching on the headlights of a car, or of momentarily switching between a headlight's high beams and low beams, in an effort to communicate with another driver or drivers. This signal is sometimes called an optical horn, since it draws the attention of other drivers.

The signal can be intended to convey a variety of messages, including a warning to other drivers of road hazards or of speed traps, and it can also be a form of aggressive driving. The legality of headlight flashing varies by jurisdiction.

History

Headlight flashing might have come into more common use as a means of attempting driver-to-driver communication by the mid-1970s, when cars began to come with headlight beam selectors located on the steering column—typically activated by pulling the turn signal stalk—rather than the previous foot-operated pushbutton switches. The signal stalk configuration was wired to permit the momentary activation of the high beams regardless of whether the headlamp switch was turned on or off.

Flashing (cinematography)

In cinematography, flashing is a method of contrast control that takes advantage of the natural physical properties of chemical-emulsion film stock to bring out detail in darker areas of the print.

The effect is produced by adding a small and even level of exposure to the entire image. Since exposure levels increase logarithmically, this tiny level of additional exposure has no practical effect on an image's mid-tones or highlights, while it shifts the darker areas of the image into the film's practical sensitivity range, thus allowing darker areas of the image to show visual detail rather than uniform black.

Flashing can be applied to the film stock before, during, or after principal photography of the film, although always before the film's processing. When applied before or after shooting, this is generally done by a motion picture film lab. The level of flashing needs to be tested ahead of time and subsequently moderated appropriately against the light levels of the scene, or else it risks having minimal impact if too low or making the shadows "milky" when too high.

.museum

museum is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet used exclusively by museums, museum associations, and individual members of the museum profession, as these groups are defined by the International Council of Museums (ICOM).

In joint action with the J. Paul Getty Trust, ICOM established the Museum Domain Management Association (MuseDoma), headed by Cary Karp, for the purpose of submitting an application to ICANN for the creation of the new generic top-level domain (gTLD), and to operate a registry. The museum domain was entered into the DNS root on 20 October 2001, and was the first sponsored top-level domain to be instituted through ICANN's action.

The purpose of this domain is to reserve a segment of the DNS name space reserved for the use of museums; a name space whose conventions are defined by the museum community. The museum TLD grants users a quick and intuitive way to verify the authenticity of a museum site. Conversely, since it is a type of formal third-party certification, museums using this name space obtain a way to assure visitors of the site's validity.

Museum

A museum (/mjuˈziːəm/; myoo-zee-um) is an institution that cares for (conserves) a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance and makes them available for public viewing through exhibits that may be permanent or temporary. Most large museums are located in major cities throughout the world and more local ones exist in smaller cities, towns and even the countryside. Museums have varying aims, ranging from serving researchers and specialists to serving the general public. The goal of serving researchers is increasingly shifting to serving the general public.

Some of the most attended museums include the Louvre in Paris, the National Museum of China in Beijing, the Smithsonian Institution in Washington, D.C., the British Museum in London, the National Gallery in London and The Metropolitan Museum of Art in New York City. There are many types of museums, including art museums, natural history museums, science museums, war museums and children's museums.

Museum (TTC)

Museum is a subway station on the Yonge–University line in Toronto, Ontario, Canada. It opened in 1963 and is located under Queen's Park at Charles Street West, beside the Royal Ontario Museum after which it is named.

Structure

The station structure was created in the middle of the road using cut and cover, while immediately south of the station the line goes into a bored tunnel to run under Queen’s Park, passing east of the Ontario Legislative Building to reach Queen's Park station. The concourse is located under the roadway, one level above the north end of a centre platform, with entrances from either side of the road. There are two stairways on the west side adjacent to the southern end of the Royal Ontario Museum and two on the east, just south of Charles Street. Pedestrians are encouraged to use the station as a pedestrian underpass to cross Queen's Park, a wide and busy thoroughfare without a centre median. This station does not have an elevator and is not wheelchair accessible.
