Isikhathi sesifikile sokushintsha ithelevishini, Futhi kungenxa yokuthi ezingeni lokuklama bebemi ndawonye iminyaka embalwa, iqiniso ukuthi ubuchwepheshe buthuthuke kabuhlungu eminyakeni emihlanu edlule, iphutha elikhulu ukufika kwezinhlelo nezinkampani zokukhiqiza ezihlakaniphile enikela ngokusakazwa kwekhwalithi ephezulu njengoku I-Netflix
Ngakho-ke lapho sihlola ukuthengwa kwe-TV entsha sizithola sinenkinga yokulungiswa, manje inselelo entsha, i-HDR. Kunezinhlobo ezahlukahlukene ze-HDR, ngayinye inamakhono ayo kepha konke okunomqondo ofanayo, ake sibone ukuthi zehluka kanjani.
Into yokuqala: Iyini i-HDR?
Ububanzi beDynamic High noma i-HDR Ngama-akhronimi uhlelo olumisiwe oluhloselwe ama-algorithms kanye nokwehluka kwemibala ngenhloso yokunikeza ubuqiniso obukhulu esithombeni esisibonayo. Ezimweni eziningi, amafilimu amnyama ngokweqile, noma imibala ifiphele kakhulu, lokhu kungenxa yokuthi iphaneli ayilungisi imininingwane efinyelela kahle kumaphikseli futhi izama ukungashintshi ngokuzumayo kombala esithombeni esifanayo. Nge-HDR esikutholayo ukujula okukhulu kumathoni amnyama namhlophe ngokwandisa umehluko futhi nakanjani kukhulisa inani lemibala ekhonjiswa ngasikhathi sinye.
Thuthukisa umehluko Kusivumela ukuthi sibheke ngokuningiliziwe ezinye izici zefilimu ukuthi ngohlelo olujwayelekile azinakwa, njengoba sishilo ngaphambili, lapho kukhona ubumnyama obukhulu noma okuphambene nalokho. Ukwandisa imibala okufezwayo ukuhlinzeka ngemibala engapheli, cishe iphindwe kayikhulu ngaphezulu kuhlaka olufanayo kunephaneli elingenayo i-HDR, okwenza izithombe zivele zicace kakhulu futhi imibala ivelele ngokwengeziwe, ngaleyo ndlela ifane nemibala yempilo yangempela.
Kungani kunezinhlobo ezahlukahlukene ze-HDR?
