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.
