sRGB ndiye malo omwe amagwiritsidwa ntchito pamitundu yowonera, kuphatikiza zithunzi ndi makanema a SDR (Standard Dynamic Range) omwe amawonedwa pa intaneti.Komanso masewera omwe adaseweredwa pansi pa SDR.Ngakhale zowonetsera zokhala ndi masewera ambiri kuposa izi zikuchulukirachulukira, sRGB ikadali yotsika kwambiri ndipo malo omwe amawonetsedwa ambiri amatha kuphimba kwathunthu kapena makamaka.Chifukwa chake, ena angakonde kugwira ntchito mkati mwa malo amtundu uwu kaya kusintha zithunzi ndi makanema kapena kupanga masewera.Makamaka ngati zomwe zilimo ziyenera kudyedwa ndi anthu ambiri, pa digito.
Adobe RGB ndi malo amitundu ambiri, opangidwa kuti aziphatikiza mithunzi yambiri yomwe osindikiza ambiri amatha kusindikiza.Pali kuwonjezeka kwakukulu kupitirira sRGB m'dera lobiriwira la gamut ndi zobiriwira mpaka m'mphepete mwa buluu, pamene zigawo zofiira ndi zabuluu zimagwirizana ndi sRGB.Chifukwa chake pali zowonjezera kupitilira sRGB kumadera amithunzi apakatikati monga cyan, yellows ndi malalanje.Ichi ndi chisankho chodziwika kwa iwo omwe amatha kusindikiza zithunzi kapena komwe zolengedwa zawo zimathera pazofalitsa zina zakuthupi.Chifukwa gamut iyi imatha kujambula mithunzi yambiri yomwe mungakumane nayo mdziko lenileni, ena amakonda kugwiritsa ntchito malo amtundu uwu ngakhale samaliza kusindikiza ntchito yawo.Izi zitha kukhala zofunikira kwambiri pakupanga zinthu zomwe zimayang'ana kwambiri 'zachilengedwe' zomwe zili ndi masamba obiriwira, mlengalenga kapena nyanja zotentha.Malingana ngati chiwonetserochi chikugwiritsidwa ntchito kuti muwone zomwe zilimo zili ndi gamut yokwanira, mitundu yowonjezerayo imatha kusangalatsidwa.
DCI-P3 ndi malo ena amitundu omwe amafotokozedwa ndi bungwe la Digital Cinema Initiatives (DCI).Ili ndiye chandamale chomwe chatsala pang'ono kuganiziridwa ndi opanga zinthu za HDR (High Dynamic Range).Ndi sitepe yapakatikati yopita ku gamut yotakata, Rec.2020, yomwe mawonedwe ambiri amapereka chidziwitso chochepa.Malo amtundu siwowolowa manja monga Adobe RGB kwa mithunzi yobiriwira mpaka yabuluu koma amapereka zowonjezera zobiriwira mpaka zofiira ndi zabuluu mpaka zofiira.Kuphatikizapo zofiira koyera, malalanje ndi zofiirira.Zimaphatikizapo mithunzi yambiri yodzaza kwambiri kuchokera kudziko lenileni lomwe likusowa ku sRGB.Imathandizidwanso kwambiri kuposa Adobe RGB, mwina chifukwa ndiyosavuta kuyipeza ndi njira zochepa zowunikira kapena zowunikira.Koma ndikupatsidwanso kutchuka kwa HDR ndi kuthekera kwa hardware kukankhira mbali imeneyo.Pazifukwa izi, DCI-P3 imakondedwa ndi ena omwe amagwira ntchito ndi makanema a SDR ndi zithunzi osati za HDR zokha.
