lens,  as  differentiated  from  the  focal  plane  or behind-the-lens shutters. Sometimes applied to an iris diaphragm whose blades operate between lens elements. SHUTTER,  FOCAL-PLANE–A  shutter  located  near the focal plane and consisting of a curtain with a slot that is pulled across the focal plane to make the exposure. The width of the slit and the speed it is moved determine the duration of the exposure. SHUTTER  RELEASE–A device to actuate a camera shutter. SHUTTER  SPEED–The length of time that light is permitted to act upon film or paper as a result of the shutter  having  opened  and  closed. SILHOUETTE –An art term for the outline of a form in black or white that is offset by a background of the  contrasting  color.  (PIA) SILVER  HALIDE–A compound of silver and one of the  following  elements  known  as  halogens: chlorine, bromide, iodine, and fluorine. (NMA) SLANT TRACK–Same as helical scan. SODIUM   HYDROXIDE   (CAUSTIC   SODA, SODIUM HYDRATE), NaOH–A   deliquescent white material usually available as pellets, flakes, or sticks. Soluble in water with the liberation of heat. A very active accelerator used in high-energy developers.  Concentrated  solutions  are  quite  caustic and will attack the skin, causing painful burns. SODIUM THIOSULFATE (THIOSULFATE OF SODA,   HYPO)   Na2S2O35H2O–Colorless   crystals, very  soluble  in  water.  It  is  the  principal  constituent of most fixing solutions. It may be available in the anhydrous  form. SOFT–(l) As applied to a photographic emulsion or developer, having a low contrast. (2) As applied to the lighting of a set, diffuse, giving a flat scene in which  the  brightness  difference  between  highlights and shadows is small. SOFT  FOCUS–An unsharp photographic image or a special  lens  or  exposing  technique  by  means  of which it is produced. (PIA) SPECIFIC GRAVITY (LIQUID AND SOLID)–The ratio of the weight of a substance to the weight of an equal volume of distilled water. SPECULAR –Like a mirror, reflecting in a regular manner  so  that  clear  images  may  be  formed, nondiffusing. SPOT–A contraction of “spotlight”; a lamp which projects a narrow, strong beam of light. (Verb) To remove spots from photographic prints, sometimes called "positive retouching" or"print retouching." SQUEEGEE–(l) A rubber blade mounted in a holder which, when drawn over the surface of a wet film or paper, removes the surface liquid. (2) Rollers used for the same purpose. (3) On continuous processing machines, air squeegees may be used that remove surface liquid by either suction or by blowing  air  against  material  being  processed. STAIN–A local or general discoloration of negatives and prints. STEP  TEST–(l) A series of exposures made with gradual  increases  in  illumination  used  to  determine proper exposure conditions. (2) To test for contrast or latitude, you can use a step wedge in a single exposure. (NMA) STOP BATH–A stop bath is an acid solution used to arrest  development  by  neutralizing  the  alkaline developer with which the photographic material is saturated  as  it  leaves  the  developing  bath. STROBE–Designates an electronic flash lamp. SUBTRACTIVE PRIMARIES–The three printing colors   used   in   three-color   subtractive   color processes: magenta (minus green), cyan (minus red), and yellow (minus blue-violet). (PIA) SYNCHROFLASH  –Photographic arrangement whereby  a  photoflash  lamp  is  timed  to  provide illumination at the instant when the camera shutter is wide open. TIME BASE CORRECTOR (TBC)–An  electronic accessory to a videotape recorder that helps make playbacks  or  transfers  electronically  stable.  A  TBC helps   to   maintain   picture   stability   even   in dubbing-up  operations. TIME  TEMPERATURE  CHART–A table showing the optimum time of development at the standard temperature  for  various  photographic  materials  in  a given   developer   or   for   different   times   of development   in   order   to   obtain   equivalent development  at  nonstandard  temperatures.  (PIA) TONE–(l) In a photographic negative or print, the degree of lightness or darkness of the various parts of the image. (2) A term applied to the color of the image in a photographic print; that is, warm, cold, sepia, and so forth. AI-14
