Photo Manipulation
Photograph manipulation involves the transformation or alteration of a photograph using various methods and techniques to achieve desired results. Some photograph manipulations are considered to be skillful artwork, while others are considered to be unethical practices, especially when used to deceive the public. Other examples include being used for political propaganda, or to improve the appearance of a product or person, or simply as entertainment or practical jokes. Depending on the application and intent, some photograph manipulations are considered an art form because it involves the creation of unique images and in some instances, signature expressions of art by photographic artists. Ansel Adams employed some of the more common manipulations using darkroom exposure techniques, burning (darkening) and dodging (lightening) a photograph. Other examples of photo manipulation include retouching photographs using ink or paint, airbrushing, double exposure, piecing photos or ...

List Of Video Editing Software
The following is a list of video editing software. The criterion for inclusion in this list is the ability to perform non-linear video editing. Most modern transcoding software supports transcoding a portion of a video clip, which would count as cropping and trimming. However, items in this article have one of the following conditions: # Can perform other non-linear video editing function such as montage or compositing # Can do the trimming or cropping without transcoding Free (libre) or open-source The software listed in this section is either free software or open source, and may or may not be commercial. Active and stable *Avidemux (Linux, macOS, Windows) * Losslesscut (Linux, macOS, Windows) * Blender VSE (Linux, FreeBSD, macOS, Windows) *Cinelerra (Linux, FreeBSD) *FFmpeg (Linux, macOS, Windows) – CLI only; no visual feedback *Flowblade (Linux) *Kdenlive (Linux, FreeBSD, macOS, Windows) *LiVES (BSD, IRIX, Linux, Solaris) *Olive (Linux, macOS, Windows) - ''currently in ...

Graphics Software
In computer graphics, graphics software refers to a program or collection of programs that enable a person to manipulate images or models visually on a computer. Computer graphics can be classified into two distinct categories: raster graphics and vector graphics, with further 2D and 3D variants. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that operate on both. It is simple to convert from vector graphics to raster graphics, but going the other way is harder. Some software attempts to do this. In addition to static graphics, there are animation and video editing software. Different types of software are often designed to edit different types of graphics such as video, photos, and vector-based drawings. The exact sources of graphics may vary for different tasks, but most can read and write files. Most graphics programs have the ability to import and export one or more graphics file formats, including those formats written for ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Assembly Language
In computer programming, assembly language (or assembler language, or symbolic machine code), often referred to simply as Assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Assembly language usually has one statement per machine instruction (1:1), but constants, comments, assembler directives, symbolic labels of, e.g., memory locations, registers, and macros are generally also supported. The first assembly code in which a language is used to represent machine code instructions is found in Kathleen and Andrew Donald Booth's 1947 work, ''Coding for A.R.C.''. Assembly code is converted into executable machine code by a utility program referred to as an ''assembler''. The term "assembler" is generally attributed to Wilkes, Wheeler and Gill in their 1951 book ''The Preparation of Programs for an Electronic Digital Com ...

Intel 8088
The Intel 8088 ("''eighty-eighty-eight''", also called iAPX 88) microprocessor is a variant of the Intel 8086. Introduced on June 1, 1979, the 8088 has an eight-bit external data bus instead of the 16-bit bus of the 8086. The 16-bit registers and the one megabyte address range are unchanged, however. In fact, according to the Intel documentation, the 8086 and 8088 have the same execution unit (EU)—only the bus interface unit (BIU) is different. The original IBM PC is based on the 8088, as are its clones. History and description The 8088 was designed at Intel's laboratory in Haifa, Israel, as were a large number of Intel's processors. The 8088 was targeted at economical systems by allowing the use of an eight-bit data path and eight-bit support and peripheral chips; complex circuit boards were still fairly cumbersome and expensive when it was released. The prefetch queue of the 8088 was shortened to four bytes, from the 8086's six bytes, and the prefetch algorithm was s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concentric Data Systems
Concentric Data Systems, Inc. was founded in December 1979 by John J. Henderson and Jonathan Sachs, both having left their jobs as system programmers at Data General Corporation. Originally, the company undertook a variety of software consulting projects for the Data General line of computers. In 1981, the company developed a spreadsheet product, CompuCalc, that ran on Data General hardware and was modeled after VisiCalc. In 1982, Sachs left and joined Mitch Kapor to found Lotus Development Corporation. Concentric transitioned to a product development company, producing a series of software products for the IBM PC. The products were a file manager, C.I.P, followed by a report writer for Lotus, 1-2-3 Report Writer, followed by a series of report writers marketed under the name R&R. The R&R products worked with dBase, FoxBase, FoxPro FoxPro was a text-based (computing), text-based Procedural programming, procedurally oriented programming language and database management s ...

Maryland
Maryland ( ) is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware and the Atlantic Ocean to its east. Baltimore is the largest city in the state, and the capital is Annapolis. Among its occasional nicknames are '' Old Line State'', the ''Free State'', and the '' Chesapeake Bay State''. It is named after Henrietta Maria, the French-born queen of England, Scotland, and Ireland, who was known then in England as Mary. Before its coastline was explored by Europeans in the 16th century, Maryland was inhabited by several groups of Native Americans – mostly by Algonquian peoples and, to a lesser degree, Iroquoian and Siouan. As one of the original Thirteen Colonies of England, Maryland was founded by George Calvert, 1st Baron Baltimore, a Catholic convert"George Calvert and Cecilius Calvert, Barons Baltimore" William Hand Browne, ...
