Míra pro zčernání (resp. zbarvení) fotografické vrstvy. Je rovna dekadickému logaritmu převrácené hodnoty (tj. zápornému logaritmu) činitele prostupu ((tzv. prostupová hustota), popř. činitele jasu ((tzv. odrazná hustota). D = -log (, resp. D = -log (. Slouží jako kritérium pro posuzování kvality mikrofilmů.
