2-20. 2-21. 2-22. 2-23. 2-24. Which  of  the  following  definitions best  describes   “emulsion  latitude”? 1. The ability of a film to reproduce  brightness differences 2. The  amount  of  deviation  from the  correct  exposure  that  will still  produce  acceptable densities 3. The  evenness  of  the  emulsion thickness  applied  to  the  film base 4. The  variation  in  film processing  time  that  still permits  the  emulsion  to  respond to the action of the fixing bath What  is  exposure  latitude? 1. The  difference  in  negative densities 2. The  amount  of  exposure variation  that  will  still produce  an  acceptable  image 3. The  minimum  exposure  required to  produce  sufficient  shadow detail 4. The  amount  of  density  produced by a given exposure What  factor(s)  determine(s) the  graininess  of  a  negative? 1. Manufacturing 2. Exposure 3. Development 4. All of the above All  processed  black-and-white  film produces  images  with  metallic silver. 1. True 2. False The ability of a emulsion to record fine detail is known by what term? 1. Clumping  action 2. Resolving  power 3. Acutance 4. Graininess 2-25. 2-26. 2-27. 2-28. 2-29. The ability of an emulsion to produce  sharp  edges  between differences  in  density  is  known by  what  term? 1. Clumping  action 2. Resolving  power 3. Acutance 4. Graininess Learning  Objective: Recognize components  of  black-and-white and color films. Film is protected from friction, scratches,   and  abrasions  before development by what part of the film? 1. Overcoating 2. Base 3. Antihalation  backing 4. Noncurl  coating What part of the film prevents light  from  reflecting  back  from the base and affecting the light- sensitive  silver  halides? 1. Overcoating 2. Emulsion 3. Antihalation  backing 4. Noncurl  coating The top emulsion layer of color film is sensitive to what color of  light? 1. Blue 2. Green 3. Red 4. Yellow What is the purpose of the yellow filter  incorporated  between  the blue and green emulsion layers of color  film? 1. To  enhance  the  contrast 2. To  prevent  blue  light  from affecting  the  middle  and  bottom emulsion  layers 3. To prevent the film from being affected  by  UV  radiation 4. To aid in printing color negatives 11
