Flag (lighting)

A flag is a device used in lighting for motion picture and still photography to block light. It can be used to cast a shadow, provide negative fill, or protect the lens from a flare. Its usage is generally dictated by the director of photography, but the responsibility for placing them can vary by region, usually devolving to either the gaffer and electricians or the key grip and lighting grips.

Flags come in a wide variety of shapes and sizes, from mere square inches ("dots and fingers") to many square feet ("meat axes"). Most "industry-standard" flags consist of a square wire frame stitched with black duvetyne, which minimizes any reflected light and keeps the flag lightweight. Flags are distinguished from larger light-cutting tools such as overhead rigs or butterflies in that they can be mounted on individual C-stands, as opposed to being affixed to collapsible frames.

The above notwithstanding, given smaller budgets or extenuating circumstances, virtually any opaque object can be used to flag light.

Flag (anime)

Flag (フラッグ, Furaggu) is a 13-episode Japanese mecha-genre anime series directed by veteran director Ryosuke Takahashi. It was broadcast as pay per view streaming web video on Bandai Channel starting on June 6, 2006. Episodes 1 and 2 were scheduled to be broadcast on the anime PPV channel SKY Perfect Perfect Choice ch160 Anime from August 18, 2006. Stylistically, the series makes use of a still and video cameraman POV, as well as "web cam" images to create a documentary-like narrative, despite being an animated drama.

Setting

Saeko Shirasu is a 25-year-old war frontline photo-journalist who became a celebrity after taking a picture of civilians raising a makeshift UN flag in war-torn Uddiyana. The image then became an instant symbol for peace. However, just before the peace agreement is achieved, the flag was stolen by an armed extremist group in order to obstruct the truce. The UN peacekeepers decide to covertly send in a SDC (pronounced as Seedac—Special Development Command) unit to retrieve the flag. Because of her connection with the "Flag" photo, Saeko Shirasu was offered the job of following the SDC unit as a frontline journalist. The SDC unit is equipped with an HAVWC (High Agility Versatile Weapon Carrier—pronounced "havoc") mecha armored vehicle.

Flag (geometry)

In (polyhedral) geometry, a flag is a sequence of faces of a polytope, each contained in the next, with just one face from each dimension.

More formally, a flag ψ of an n-polytope is a set {F₋₁, F₀, ..., F_n} such that F_i ≤ F_i+1 (−1 ≤ i ≤ n − 1) and there is precisely one F_i in ψ for each i, (−1 ≤ i ≤ n). Since, however, the minimal face F₋₁ and the maximal face F_n must be in every flag, they are often omitted from the list of faces, as a shorthand. These latter two are called improper faces.

For example, a flag of a polyhedron comprises one vertex, one edge incident to that vertex, and one polygonal face incident to both, plus the two improper faces. A flag of a polyhedron is sometimes called a "dart".

A polytope may be regarded as regular if, and only if, its symmetry group is transitive on its flags. This definition excludes chiral polytopes.

Incidence geometry

In the more abstract setting of incidence geometry, which is a set having a symmetric and reflexive relation called incidence defined on its elements, a flag is a set of elements that are mutually incident. This level of abstraction generalizes both the polyhedral concept given above as well as the related flag concept from linear algebra.

Dirt

Dirt is unclean matter, especially when in contact with a person's clothes, skin or possessions when they are said to become dirty. Common types of dirt include:

Exhibitions and studies

A season of artworks and exhibits on the theme of dirt was sponsored by the Wellcome Trust in 2011. The centrepiece was an exhibition at the Wellcome Collection showing pictures and histories of notable dirt such as the great dust heaps at Euston and King's Cross in the 19th century and the Fresh Kills landfill which was once the world's largest.

Foci

Computer keyboards are especially dirty as, on average, they contain 70 times more microbes than a lavatory seat.

Cleaning

When things are dirty they are usually cleaned with solutions like hard surface cleaner and other chemicals; much domestic activity is for this purpose — washing, sweeping and so forth.

Dirt!

Dirt! is the sixth album by the Canadian comedy music group The Arrogant Worms, released in 1999.

Dirt (Florida Georgia Line song)

"Dirt" is a song recorded by American country music duo Florida Georgia Line. It is the first single from their sophomore studio album Anything Goes, which was released on October 14, 2014.

Content

Written by Rodney Clawson and Chris Tompkins, the song is a mid-tempo ballad about various life events centering on dirt.

The final lines of the song include the lyrics "You know you came from it / Someday you'll return to it", which the duo initially did not want to include as they felt it was a cliché. However they eventually decided to include the line. Brian Kelley, one-half of the duo, told the Chicago Sun-Times, "I think a 'Cruise'-type song would have been accepted, but just when you think you have FGL figured out, we wanted to go against the grain and change it up with a song like 'Dirt'".

Music video

The music video was directed by Nigel Dick. It follows the life of a married couple, alternating between the past and present, where the family is gathered for the mother's funeral. It stars J. D. Souther in the leading role and Lindsay Heyser as the young Rosie.
