Photography is the art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing, and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. A person who makes photographs is called a photographer.
Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. "Halftone" can also be used to refer specifically to the image that is produced by this process.
In photography and cinematography, a normal lens is a lens that reproduces a field of view that appears "natural" to a human observer. In contrast, depth compression and expansion with shorter or longer focal lengths introduces noticeable, and sometimes disturbing, distortion.
The Yoshizawa–Randlett system is a diagramming system used to describe the folds of origami models. Many origami books begin with a description of basic origami techniques which are used to construct the models. There are also a number of standard bases which are commonly used as a first step in construction. Models are typically classified as requiring low, intermediate or high skill depending on the complexity of the techniques involved in the construction.
Group f/64 or f.64 was a group founded by seven American 20th-century San Francisco Bay Area photographers who shared a common photographic style characterized by sharply focused and carefully framed images seen through a particularly Western (U.S.) viewpoint. In part, they formed in opposition to the pictorialist photographic style that had dominated much of the early 20th century, but moreover, they wanted to promote a new modernist aesthetic that was based on precisely exposed images of natural forms and found objects.
Steven Pippin is an English photographer and installation artist. Pippin works with converted or improvised photographic equipment and kinetic sculptures which are often based on physical models and are metaphors for social mechanisms.
Andreas Bernhard Lyonel Feininger was an American photographer and a writer on photographic technique. He was noted for his dynamic black-and-white scenes of Manhattan and for studies of the structures of natural objects.
Aerial survey is a method of collecting geomatics or other imagery by using airplanes, helicopters, UAVs, balloons or other aerial methods. Typical types of data collected include aerial photography, Lidar, remote sensing and also geophysical data (such as aeromagnetic surveys and gravity. It can also refer to the chart or map made by analysing a region from the air. Aerial survey should be distinguished from satellite imagery technologies because of its better resolution, quality and atmospheric conditions. Today, aerial survey is sometimes recognized as a synonym for aerophotogrammetry, part of photogrammetry where the camera is placed in the air. Measurements on aerial images are provided by photogrammetric technologies and methods.
The rule of thirds is a "rule of thumb" for composing visual images such as designs, films, paintings, and photographs. The guideline proposes that an image should be imagined as divided into nine equal parts by two equally spaced horizontal lines and two equally spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections. Aligning a subject with these points creates more tension, energy and interest in the composition than simply centering the subject.
Cropping is the removal of unwanted outer areas from a photographic or illustrated image. The process usually consists of the removal of some of the peripheral areas of an image to remove extraneous visual data from the picture, improve its framing, change the aspect ratio, or accentuate or isolate the subject matter from its background. Depending on the application, this can be performed on a physical photograph, artwork, or film footage, or it can be achieved digitally by using image editing software. The process of cropping is common to the photographic, film processing, broadcasting, graphic design, and printing businesses.
The term composition means "putting together". It can be thought of as the organization of the elements of art according to the principles of art. Composition can apply to any work of art, from music through writing and into photography, that is arranged using conscious thought.
Line engraving is a term for engraved images printed on paper to be used as prints or illustrations. The term is mainly used in connection with 18th- or 19th-century commercial illustrations for magazines and books or reproductions of paintings. It is not a technical term in printmaking, and can cover a variety of techniques, giving similar results.
Jay Hambidge (1867–1924) was an American artist who formulated the theory of "dynamic symmetry", a system defining compositional rules, which was adopted by several notable American and Canadian artists in the early 20th century.
Michael Wolf was a German born artist and photographer who captured daily life in big cities. His work takes place primarily in Hong Kong and Paris and focuses on architectural patterns and structures, as well as the documentation of human life and interaction in the city. Wolf has published multiple photo books, has had his work exhibited widely around the world, has permanent collections across Germany and the United States, and has won three World Press Photo Awards from 2005 to 2011.
Miss La La at the Cirque Fernando is an oil on canvas painting by the French Impressionist artist Edgar Degas. Painted in 1879 and exhibited at the Fourth Impressionist Exhibition in Paris that same year, it is now in the collection of the National Gallery in London. It is Degas's only circus painting, and Miss La La is the only identifiable person of color in Degas's works. The special identity of Miss La La and the great skills Degas used in painting her performance in the circus made this piece of art important, widely appreciated but, at the same time, controversial.
In photography and cinematography, headroom or head room is a concept of aesthetic composition that addresses the relative vertical position of the subject within the frame of the image. Headroom refers specifically to the distance between the top of the subject's head and the top of the frame, but the term is sometimes used instead of lead room, nose room or 'looking room' to include the sense of space on both sides of the image. The amount of headroom that is considered aesthetically pleasing is a dynamic quantity; it changes relative to how much of the frame is filled by the subject. Rather than pointing and shooting, one must compose the image to be pleasing. Too much room between a subject's head and the top of frame results in dead space.
Rabatment of the rectangle is a compositional technique used as an aid for the placement of objects or the division of space within a rectangular frame, or as an aid for the study of art.
Wall Street is a platinum palladium print photograph by the American photographer Paul Strand taken in 1915. There are currently only two vintage prints of this photograph with one at the Whitney Museum of American Art and the other, along with negatives, at the Philadelphia Museum of Art. This photograph was included in Paul Strand, circa 1916, an exhibition of photographs that exemplify his push toward modernism.
The golden triangle rule is a rule of thumb in visual composition for photographs or paintings, especially those which have elements that follow diagonal lines. The frame is divided into four triangles of two different sizes, done by drawing one diagonal from one corner to another, and then two lines from the other corners, touching the first at 90-degree angles. There are a couple ways this can be used:
The Destroyed Room is a color photograph executed by Jeff Wall in 1978. The photograph was entirely created in a set and depicts a room with several damaged items, while the walls also show signs of destruction. The picture has the dimensions of 159 by 234 cm and is exhibited in a lightbox. It is held in the collection of the National Gallery of Canada, in Ottawa.
