Gamma je zkratka pro gama korekci, co\u017e je nestandardizovan\u00e1 metoda m\u011b\u0159en\u00ed kontrastu pro skenery, monitory a fotografick\u00e9 materi\u00e1ly.<\/p>\n

V pozad\u00ed gama korekce je skute\u010dnost, \u017ee lidsk\u00e9 oko nevn\u00edm\u00e1 rovnom\u011brn\u00fd p\u0159echod od b\u00edl\u00e9 k \u010dern\u00e9 matematicky line\u00e1rn\u011b. V lidsk\u00e9m vn\u00edm\u00e1n\u00ed kontrast ve sv\u011btl\u00fdch oblastech stoup\u00e1 m\u00e9n\u011b prudce, zat\u00edmco v tmav\u00fdch oblastech stoup\u00e1 strm\u011bji.<\/p>\n

Hodnota gama 1,0 znamen\u00e1, \u017ee se kontrast nem\u011bn\u00ed. Historicky se pro monitory Mac doporu\u010dovala hodnota gamma 1,8, zat\u00edmco u\u017eivatel\u016fm Windows se standardn\u011b doporu\u010dovala hodnota gamma 2,2. Dnes se pro po\u010d\u00edta\u010de Mac i Windows doporu\u010duje gama 2,2.<\/p>\n
