LAW  OF  REFLECTION–The angle of reflection is equal  to  the  angle  of  incidence. LENS–In  photography,  the  optical  instrument  or arrangement  of  light-refracting  elements  in  a  group; the whole designed to collect and distribute rays of light in the formation of an image. LENS,  COMPOUND–A lens composed of two or more separate elements with a common axis. (PIA) LENS, MIRROR–One  employing  reflecting  elements in addition to light-transmitting elements; usually to obtain compactness in telephoto objectives. (PIA) LENS ELEMENTS–Individual simple lenses that are combined to form a compound lens. (PIA) LIGHT,  AMBIENT–Surrounding  light;  the  general room  illumination  or  light  level. LIGHT,  DIFFUSED–Light that does not reach the subject in a single beam but is scattered by a medium, such as clouds, ground glass, spun glass, or thin fabric. LIGHT, FILL-IN–Secondary  illumination  directed  to illuminate shadow areas and avoid excess contrast. Also known as fill light. (PIA) LIGHT,  INCIDENT–The light that strikes an object, distinguished from the light reflected from or transmitted by the object. (PIA) LIGHT,  POLARIZED–Light in which the electric vector of the wave vibrates in one plane, rather than all planes, as it does in ordinary (unpolarized) light. Light may become polarized by reflection or by passing  through  optical  devices  or  sheets  known  as “polarizers.” LIGHT  BOX–A  device  for  viewing  transparencies  or negatives,  providing  diffuse  illumination  evenly dispersed  over  the  viewing  area. LIGHT SENSITIVE–Materials  that  undergo  changes when  exposed  to  light.  The  commonly  used photographic  light-sensitive  materials  are  the  silver halides used in films and papers, diazo dyes, and bichromated gelatin. (PIA) LIGHTING,  FLAT–Illumination  of  a  photographic subject often achieved by frontlighting or multiple sources  with  diffusers  that  minimizes  contrasts  and shadows. (PIA) LIGHTING,  FRONT–Illumination  on  the  subject coming from near the camera position. (PIA) LIGHTING,  INDIRECT–Illumination by means of light  reflected  to  the  scene  from  shielded  sources. LIGHTING,  LOW  KEY–A type of lighting which when applied to a scene results in a picture having gradations  from  middle  gray  to  black,  with comparatively limited areas of light gray and whites. LINE COPY–A  document  consisting  essentially  of  two tones (such as black and white, black and tinted, and brown  and  buff)  without  intermediate  tones. LITER–A  unit  of  capacity  in  the  metric  system, equivalent  to  1.056  quarts  in  United  States customary liquid measurement. (PIA) LOADING–The insertion of photographic film, plates, or paper into holders, hangers, magazines, and so forth,  before  exposure  or  processing. LONG SHOT–In motion pictures, a scene filmed at a considerable distance from the camera to establish locale.   Also   applied   to   scenes   which   show full-length figures, as opposed to waist-length, head and shoulders, and so forth. LOW-ANGLE  (SHOT)–Where camera is placed low and the scene is photographed at an upward angle. LUX–Lumen per square meter, a unit of illuminance. MASK–(l) An opaque sheet of thin material used to limit the area of a picture or to secure white margins on a photograph. (2) A supplementary negative or positive  used  for  the  purpose  of  contrast  correction in  black-and-white  prints.  (3)  A  supplementary positive either on a separate sheet or incorporated in an integral color tripack negative for the purpose of color correction. (PIA) MATTE–A  relatively  dull  surface  on  photographic prints,  having  a  very  low  level  of  specular reflection. MATTE BOX–A device attached to the front of a camera to hold mattes, filters, diffusing screens, and so forth, in front of the lens. MEDIUM–Any substances or space through which light  can  travel. METER–A unit of length measurement in the metric system  approximately  equal  to  39.37  inches. METOL-HYDROQUINONE   (M-Q)–Designating photographic developers that use a combination of metol  and  hydroquinone  as  the  developing  agent. AI-10
