English

Subject field(s)
  • Micrographics
DEF

(l) a relationship of image tones in which the light and dark areas are represented by average or normal differences in density.(2) Photographic materials whose sensitometric curve has normal values of average gradient, i. e., an average gradient of l. ll to l. 80.
