Indlela Yokusebenzisa Ukulinganisela Okumhlophe Kwamacala Ahlukile Okukhanyisa
Ukukhanya kunamazinga ahlukahlukene okushisa kombala kulo lonke usuku. Lokhu kubaluleke kakhulu ukwazi uma udutshulwa izithombe .
Ngaphakathi kwezithombe, ibhalansi emhlophe yinkqubo yokukhipha umbala wombala okwakhiqiza amazinga okushisa ahlukahlukene. Iso lomuntu lingcono kakhulu ekucubungeni umbala, futhi singakwazi njalo ukuthi yini okufanele ibe mhlophe esithombeni.
Esikhathini esiningi, ukulungiswa kwe-Auto White Balance (AWB) ku-ikhamera yakho ye- DSLR noma iphuzu eliphambili kanye nekhamera yokudubula kuzobonisa ukuthi kunembile kakhulu. Nokho, ngezinye izikhathi ikhamera yakho ingadideka, idinga usizo oluncane. Yingakho ikhamera yakho iza ngezindlela ezihlukahlukene zokusiza ukulwa nezimo ezibucayi kakhulu zokukhanyisa. Zilezi zilandelayo.
AWB
Kumodi ye-AWB, ikhamera ithatha inketho "yokuqagela okungcono", ngokuvamile ukukhetha ingxenye ecacile yesithombe njengephuzu elimhlophe. Lolu khetho luvame ukuba lube nolunembile kakhulu, ngaphandle kokukhanyisa kwemvelo, okukhanyayo.
Ukukhanya kwelanga
Lona ukhetho lokumhlophe oluhle uma ilanga likhanya kakhulu (cishe emini). Yengeza amathoni afudumele esithombeni ukulwa nokushisa okuphezulu kakhulu kombala.
Kupholile
Imodi efumayo yukusetshenziswa lapho ilanga lisaphuma, nesembozo sefu esiphakathi. It ishayela amathoni afudumele, kodwa kubheka isimo kancane cooler ukukhanya.
Umthunzi
Uzofuna ukusebenzisa imodi ye-shade uma isihloko sakho sisezikhunzini ngosuku olususayo, noma lapho uhlangana nosuku olunamafu, olunomfutho, noma olunomsoco.
I-Tungsten
Kufanele usebenzise ukulungiselelwa kwe-tungsten ngama-bulbs evamile emakhaya, okukhipha umbala we-orange.
I-fluorescent
Uma uhlangabezana nezibani zendabuko ye-fluorescent, uzofuna ukusebenzisa imodi ye-fluorescent. Izibani ze-fluorescent zithumela umbala ohlaza okwesibhakabhaka. Ikhamera ingeza amathoni abomvu ukulwa nalokhu.
Flash
Imodi ye-flash yukusetshenziswa ngezimpawu zokukhanya, ama-flashguns, nokukhanyisa okunye kwe-studio.
Kelvin
Ezinye ze-DSLRs zinenketho yemodi ye-Kelvin, okuvumela umthwebuli wezithombe ukuba abeke ukushisa okuqondile kombala okufunayo.
Ngokwezifiso
Imodi yangokwezifiso ivumela abathwebuli bezithombe ukusetha ibhalansi emhlophe ngokwabo, besebenzisa isithombe sokuhlola.
Zonke lezi zikhetho zingasiza, kodwa lezo ozidingayo ngempela ukuthi ziyi-tungsten, fluorescent, kanye nezilungiselelo zenkambiso.
Ukubeka konke ndawonye
Ake siqale nge-tungsten. Uma ubeka izithombe ngaphakathi, futhi umthombo wokukhanya kuphela ovela enombolweni enkulu yama-bulbs omndeni, kungcono ukubeka ibhalansi yakho emhlophe kwimodi ye-tungsten ukuze usize ikhamera ithole izinto kahle. Uma kungenjalo, ugijima engozini yokwakheka kwe-orange enhle kakhulu ezithombeni zakho!
Ukukhanyisa kwe-fluorescent kwakungelula, njengoba kuhlale kukhishwe umbala ohlaza okwesibhakabhaka. Amakhamera asekudala asekudala, ngokulungiselelwa okukodwa kwe-fluorescent, azokwazi ukuphatha ngokwanele inombolo encane yezibani zokuhlunga ze-fluorescent. Kodwa, uma usesakhiweni esinokukhanyisa okwakamuva, ama-fluorescent amaqabunga azohlinzeka ngemidwebo enemibala ehlukahlukene, evamile eluhlaza okwesibhakabhaka nohlaza. Uma une-DSLR entsha, uzoqaphela ukuthi abakhiqizi baqale ukufaka ukhetho lwesibili lwe-fluorescent ukuze ubhekane nokukhanya okunamandla okufakelwayo. Ngakho-ke, amasethingi amabili e-fluorescent kufanele-avulele lo mbala onamandla kakhulu.
Kodwa kuthiwani uma unomfanekiso omdala, futhi awukwazi ukubhekana nombala oqinile owenziwe? Noma kuthiwani uma udutshulwa esimweni esinomsoco wokukhanya okufakelwayo nokukhanya? Futhi kuthiwani uma ngabe abamhlophe abasesithombeni sakho badinga ngempela ukuba bahlanzekile abamhlophe? (Ngokwesibonelo, uma udutshulwa endaweni yemidlalo enemvelaphi emhlophe, ngokuqinisekile awufuni ukuthi imfucumfucu ivulekele!)
Kulezi zimo, inketho ye-Custom White Balance iyindlela yokuhamba. Ngokwezifiso ivumela umthwebuli wezithombe ukuthi afundise ikhamera ngalokho okufanele akuthathe. Ukusebenzisa ukulungiselelwa kwesiko, uzodinga ukutshala imali "ekhadini elimpunga." Lezi bits ezilula zekhadi zinemibala eluhlaza futhi zilinganiselwe ku-18% yegrey, e-emibhalweni yezithombe - ingaphakathi emkhatsini we-white white nehlanzekile emnyama. Ngaphansi kwezimo zokukhanyisa ezizosetshenziselwa isithombe, umthwebuli wezithombe uthatha isibhamu ngekhadi elimpunga egcwalisa ifreyimu. Khona-ke ekukhetheni inkambiso kwimenyu yokulinganisela emhlophe, ikhamera izocela umthwebuli wezithombe ukuthi akhethe ukudubula okumele kusetshenziswe. Vele ukhethe isithombe sekhadi elimpunga, futhi ikhamera izosebenzisa lesi sithombe ukuze ihlulele okumele kube mhlophe ngaphakathi kwesithombe. Ngoba isithombe sisethelwe ku-18% grey, abamhlophe nabamnyama esithombeni bazohlale benembile.
