Thola kabanzi mayelana ne-HDR noma i-High Dynamic Range uma kuziwa ezithombeni
I-High Dynamic Range, noma i- HDR , inqubo yezithombe zedijithali lapho ukuvezwa okuningi kwe-scene efanayo kufakwe khona futhi kuhlangene usebenzisa isofthiwe yokuhlela isithombe ukudala isithombe esingokoqobo noma umphumela omkhulu. Ukuzibandakanya okuhlangene kungabonisa ububanzi obukhulu bezinhlamvu ze-tonal kunalokho ikhamera yedijithali ekwazi ukurekhoda ngomfanekiso owodwa.
I-Adobe Photoshop nabanye abahleli abaningi bezithombe nezinhlelo zokusebenza zedijithali zamnyama zinikeza amathuluzi nezici ukudala imiphumela ephezulu yokuhlelwa kwebala. Abadwebi bezithombe abafisa ukuhlola isithombe se-HDR kwisofthiwe yokuhlela isithombe kumele bathathe uchungechunge lwezithombe ezijwayelekile ezidubula ngokuchayeka okuhlukene, ngokuvamile nge-tripod nokukhishwa kwe-bracketing.
Hlanganisa nesici se-HDR
I-Adobe Photoshop yaqala ukufaka amathuluzi we-HDR ngo-2005 nge-"Ukuhlanganisa ku-HDR" isici ku- Photoshop CS2 . Ngonyaka ka-2010 ngokukhululwa kwe-Photoshop CS5, lesi sici senezelwa ku-HDR Pro, senezela izinketho eziningi nokulawula. I-Photoshop CS5 iphinde ithele isici se-HDR Toning, esivumela abasebenzisi ukuba balingise imiphumela ye-HDR besebenzisa isithombe esisodwa kunokuba badinga ukuvezwa okuningi ukuthunjwa kusengaphambili.
Yize umsebenzi omkhulu onzima ukwenziwa ngempela ekubanjeni izithombe ezisetshenziselwa i-HDR, ukuguqula umphumela owenziwe ngokungafani kakhulu, isithombe esiphezulu semininingwane ngokuvamile sidinga umuntu abe nolwazi oluseduze ngamathuluzi ahlukahlukene ku-Lightroom noma ku-Photoshop ukuze akhe ilungelo nje bheka isithombe sokugcina.
Ukufanekisa Izinhlelo Zokudala i-HDR Izithombe
Kunezinhlelo zokusebenza eziningi zokucabanga ezizinhloso zayo kuphela ukudala izithombe ze-HDR. Omunye wabo, i-Aurora HDR, ilungele abantu abafisa ukuhlola lesi sihloko esiyinkimbinkimbi ngaphandle kolwazi olujulile lwezindlela zamathuluzi ezisetshenziselwa ukudala lezi zithombe. Isici esisodwa esiwusizo kakhulu se-Aurora HDR ukuthi singasetshenziswa kufakwe njenge-plugin Photoshop.
