Gradarea descrie: trepte de tonuri. Reproducerea treptelor de tonuri ale unei imagini originale \u00eentr-un alt produs, de exemplu ca \u0219ablon de copiere \u0219i \u00een tipar.<\/p>\n

Tehnica de reproducere: capacitatea unui material fotografic de a reproduce gradele de ton ale unei imagini originale \u00een anumite condi\u021bii de procesare (expunere, developare, substan\u021be chimice). Termenul se refer\u0103 la contrastul unui material fotografic developat. Valoarea grad\u0103rii se cite\u0219te din panta p\u0103r\u021bii liniare a curbei caracteristice, numit\u0103 gamma<\/a>.<\/p>\n

\u00cen cazul materialelor fotografice, se face distinc\u021bia \u00eentre gradele de grada\u021bie \u00eentre moale \u0219i ultra-abrupt. O grada\u021bie ultra-abrupt\u0103 (foarte dur\u0103) reproduce doar dou\u0103 valori tonale, de exemplu alb \u0219i negru. Cu c\u00e2t grada\u021bia este mai moale, cu at\u00e2t mai multe valori de luminozitate diferite se afl\u0103 \u00eentre alb \u0219i negru.<\/p>","protected":false},"excerpt":{"rendered":"
