Catch Light
Catch light or catchlight is a light source that causes a specular highlight in a subject's eye in an image; the term may also refer to the highlight itself. They are also referred to as eye lights or Obies, the latter a reference to Merle Oberon, for whom the light was invented by then husband and cinematographer, Lucien Ballard. The catch light is either an artifact for a lighting method, or purposely engineered to add a ''glint'' or ''spark'' to a subject's eye during photography. The technique is effective in both still and motion picture photography; helping to draw attention towards the subject's eyes, which may otherwise get lost among other elements in the scene. History The lighting instrument was invented during filming of '' The Lodger'', on which Oberon's husband was the cinematographer. Ballard wanted to alleviate Oberon's facial scars following a car accident in 1937, successfully done through make up and good lighting; attaching a small light mount on the side of ...

Red-eye Effect
The red-eye effect in photography is the common appearance of red pupils in color photographs of the eyes of humans and several other animals. It occurs when using a photographic flash that is very close to the camera lens (as with most compact cameras) in ambient low light. Causes In flash photography the light of the flash occurs too fast for the pupil to close, so much of the very bright light from the flash passes into the eye through the pupil, reflects off the fundus at the back of the eyeball and out through the pupil. The camera records this reflected light. The main cause of the red color is the ample amount of blood in the choroid which nourishes the back of the eye and is behind the retina. The blood in the retinal circulation is far less than in the choroid, and plays virtually no role. The eye contains several photostable pigments that all absorb in the short wavelength region, and hence contribute somewhat to the red eye effect. The lens cuts off deep blue and ...

Photographic Techniques
Photography is the art, application, and practice of creating durable 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 (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

Anime
is Traditional animation, hand-drawn and computer animation, computer-generated animation originating from Japan. Outside of Japan and in English, ''anime'' refers specifically to animation produced in Japan. However, in Japan and in Japanese, (a term derived from a shortening of the English word ''animation'') describes all animated works, regardless of style or origin. Animation produced outside of Japan with similar style to Japanese animation is commonly referred to as anime-influenced animation. The earliest commercial Japanese animations date to 1917. A characteristic art style emerged in the 1960s with the works of cartoonist Osamu Tezuka and spread in following decades, developing a large domestic audience. Anime is distributed theatrically, through television broadcasts, Original video animation, directly to home media, and Original net animation, over the Internet. In addition to original works, anime are often adaptations of Japanese comics (manga), light novels, ...

Trope (literature)
A literary trope is the use of figurative language, via word, phrase or an image, for artistic effect such as using a figure of speech. Keith and Lundburg describe a trope as, "a substitution of a word or phrase by a less literal word or phrase." The word ''trope'' has also come to be used for describing commonly recurring or overused literary and rhetorical devices, motifs or clichés in creative works. Literary tropes span almost every category of writing, such as poetry, film, plays, and video games. Origins The term ''trope'' derives from the Greek (''tropos''), "turn, direction, way", derived from the verb τρέπειν (''trepein''), "to turn, to direct, to alter, to change". Tropes and their classification were an important field in classical rhetoric. The study of tropes has been taken up again in modern criticism, especially in deconstruction. Tropological criticism (not to be confused with tropological reading, a type of biblical exegesis) is the historical study of ...

Portraiture
A portrait is a painting, photograph, sculpture, or other artistic representation of a person, in which the face and its expressions are predominant. The intent is to display the likeness, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, in order to most successfully engage the subject with the viewer. History Prehistorical portraiture Plastered human skulls were reconstructed human skulls that were made in the ancient Levant between 9000 and 6000 BC in the Pre-Pottery Neolithic B period. They represent some of the oldest forms of art in the Middle East and demonstrate that the prehistoric population took great care in burying their ancestors below their homes. The skulls denote some of the earliest sculptural examples of portraiture in the history of art. Historical portraitur ...

Retina
The retina (from la, rete "net") is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the film or image sensor in a camera. The neural retina consists of several layers of neurons interconnected by synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rods and cones. Rods function mainly in dim light and provide monochromatic vision. Cones function in well-lit conditions and are responsible for the perception of colour through the use of a range of opsins, as well as high-acuity vision used for task ...

Cornea
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. The cornea can be reshaped by surgical procedures such as LASIK. While the cornea contributes most of the eye's focusing power, its focus is fixed. Accommodation (the refocusing of light to better view near objects) is accomplished by changing the geometry of the lens. Medical terms related to the cornea often start with the prefix "'' kerat-''" from the Greek word κέρας, ''horn''. Structure The cornea has unmyelinated nerve endings sensitive to touch, temperature and chemicals; a touch of the cornea causes an involuntary reflex to close the eyelid. Because transparency is of prime importance, the healthy cornea does not have or need blood vessels with ...

Specular Highlight
A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image on right). Specular highlights are important in 3D computer graphics, as they provide a strong visual cue for the shape of an object and its location with respect to light sources in the scene. Microfacets The term ''specular'' means that light is perfectly reflected in a mirror-like way from the light source to the viewer. Specular reflection is visible only where the surface normal is oriented precisely halfway between the direction of incoming light and the direction of the viewer; this is called the half-angle direction because it bisects (divides into halves) the angle between the incoming light and the viewer. Thus, a specularly reflecting surface would show a specular highlight as the perfectly sharp reflected image of a light source. However, many shiny objects show blurred specular highlights. This can be explained by the existence of microfacets. W ...

Soft Box
A soft box is a type of photographic lighting device, one of a number of photographic soft light devices. All the various soft light types create even and diffused lightBrooks, David. ''How to Control and Use Photographic Lighting''. HPBooks, 1980, p. 54. by transmitting light through some scattering material, or by reflecting light off a second surface to diffuse the light. The best known form of reflective source is the umbrella light, where the light from the bulb is "bounced" off the inside of a metalized umbrella to create an indirect "soft" light. A soft box is an enclosure around a bulb comprising reflective side and back walls and a diffusing material at the front of the light. The sides and back of the box are lined with a bright surface - an aluminized fabric surface or an aluminum foil, to act as an efficient reflector. In some commercially available models the diffuser is removable to allow the light to be used alone as a floodlight or with an umbrella reflecto ...

Ring Flash
A ring flash is a circular light that is often operated with a camera lens in the center to take photographs. Unlike point light sources, a ring flash can illuminate a subject with minimal shadows by closely and evenly surrounding the optical axis of the camera lens. This makes it a popular choice for various types of photography, including macro, portrait and fashion photography. Closely related to the ring flash is the continuous ring light, which can produce a consistent level of light for video recording or to see a live preview before capturing photographs. Continuous ring lights are popular for improving picture quality on video calls, social media selfies, and video blogging. For example, Cornell University offers a photo kiosk equipped with a continuous ring light and iPad to take social media profile pictures for students, faculty, staff, and alumni. Modern continuous ring lights frequently use light-emitting diodes (LEDs) because they are bright, energy-efficient, an ...
