Screen (magazine)

Screen is a leading weekly film magazine, published in India. Established in 1951, it is owned by The Indian Express publishing group. The content focuses on India's Hindi film industry, a.k.a. Bollywood, located mainly in Mumbai. It also has an e-magazine version.

History

Screen was first published on 26 September 1951 with Manorama Katju as its managing editor. She was succeeded in 1959 by S.S. Pillai who died in office in 1977. The magazines was started by the Indian Express newspaper group.

B. K. Karanjia who was previously editor of Filmfare, stayed Screen editor for 10 years.Udaya Tara Nayar, rose the ranks within Screen Magazine and became the editor between 1988-1996 and 1998-2000. Veteran film journalist, Bhawana Somaaya was the editor of the magazine (2000-2007). In 2007 she was replaced by Ex- Society Magazine and HT Style/Saturday editor Priyanka Sinha Jha who remains the editor till date.

Screen Awards

Screen organizes and sponsors the Screen Awards for movies in Hindi cinema, established in 1995. It also sponsors Screen Gold Medal for excellence in direction at the Film and Television Institute, established in 1967.

Blend modes

Blend modes (or Mixing modes) in digital image editing are used to determine how two layers are blended into each other. The default blend mode in most applications is simply to hide the lower layer with whatever is present in the top layer. However, as each pixel has a numerical representation, a large number of ways to blend two layers is possible. Note that the top layer is not necessarily called a "layer" in the application. It may be applied with a painting or editing tool.

Most graphics editing programs, like Adobe Photoshop and GIMP, allow the user to modify the basic blend modes - for example by applying different levels of opacity to the top picture.

Normal blend mode

This is the standard blend mode which uses the top layer alone, without mixing its colors with the layer beneath it.

Where a is the value of a color channel in the underlying layer, and b is that of the corresponding channel of the upper layer. The result is most typically merged into the bottom layer using "simple" (b over a) alpha compositing, but other Porter-Duff operations are possible. The compositing step results in the top layer's shape, as defined by its alpha channel, appearing over the bottom layer.

Conclusion (music)

In music, the conclusion is the ending of a composition and may take the form of a coda or outro.

Pieces using sonata form typically use the recapitulation to conclude a piece, providing closure through the repetition of thematic material from the exposition in the tonic key. In all musical forms other techniques include "altogether unexpected digressions just as a work is drawing to its close, followed by a return...to a consequently more emphatic confirmation of the structural relations implied in the body of the work."

For example:

End (graph theory)

In the mathematics of infinite graphs, an end of a graph represents, intuitively, a direction in which the graph extends to infinity. Ends may be formalized mathematically as equivalence classes of infinite paths, as havens describing strategies for pursuit-evasion games on the graph, or (in the case of locally finite graphs) as topological ends of topological spaces associated with the graph.

Ends of graphs may be used (via Cayley graphs) to define ends of finitely generated groups. Finitely generated infinite groups have one, two, or infinitely many ends, and the Stallings theorem about ends of groups provides a decomposition for groups with more than one end.

Definition and characterization

Ends of graphs were defined by Rudolf Halin (1964) in terms of equivalence classes of infinite paths. A ray in an infinite graph is a semi-infinite simple path; that is, it is an infinite sequence of vertices v₀, v₁, v₂, ... in which each vertex appears at most once in the sequence and each two consecutive vertices in the sequence are the two endpoints of an edge in the graph. According to Halin's definition, two rays r₀ and r₁ are equivalent if there is another ray r₂ (not necessarily different from either of the first two rays) that contains infinitely many of the vertices in each of r₀ and r₁. This is an equivalence relation: each ray is equivalent to itself, the definition is symmetric with regard to the ordering of the two rays, and it can be shown to be transitive. Therefore, it partitions the set of all rays into equivalence classes, and Halin defined an end as one of these equivalence classes.
