Ukukhanya kweFilimu ye-LED xa kuthelekiswa nesibane sombane
Ukuthetha ngezibane zokufota, wonke umntu umele ukuba weva nge-flash kunye ne-led fill light. Kwiifoto zemihla ngemihla, ngaba kungcono ukusebenzisa isibane sokugcwalisa i-LED okanye isibane? Kulo shicilelo, siya kuzisa iingenelo kunye nokungalunganga kweentlobo ezimbini zefoto yokugcwalisa ukukhanya ngokweenkcukacha, ukuze wonke umntu abe nolwazi olubanzi kwaye unokukhetha isibane esifanelekileyo sokufota kwindalo yokudubula.
Masithethe malunga nesibane sokuzalisa i-LED, olu luhlobo lokukhanya okungaguqukiyo, kusetyenziswa ukuqaqamba okuphezulu kwe-LED njengomthombo wokukhanya ophambili, eyona nto inkulu yile "into oyibonayo yile nto uyifumanayo" gcwalisa ukukhanya. Ukusebenza okulula, ukuguquguquka okubanzi, ubomi obusebusweni Imiboniso yokudubula ilungile, njengemifanekiso ekufutshane, ukuzaliswa okubukhoma, ukurekhoda kwevidiyo, ukukhanya kweqonga, njl.njl. Logama uziva ukhanyiswe luzizi, ungazisebenzisa ukugcwalisa ukukhanya. Undoqo kukuba ingabizi.
Emva kokufunda i-led fill light, siqhubeka sithetha isibane esikhanyisayo. Olona hlobo luqhelekileyo lwesibane sesibane siphezulu isihlangu esishushu. Ngokuqinisekileyo, ukukhanya okusilinda okufihlwe kwibhokisi yokukhanya xa uthatha ifoto nako kukukhanya. Isibane sesona sikhanyiso sixhaphakileyo sisetyenziswa ekufotweni komtshato kunye nefoto yesitudiyo sokufota. Enye yezo zinto ziqhelekileyo zikwangowona mahluko mkhulu ukusuka ekukhanyeni rhoqo, oko kukuthi, amandla aya kuba makhulu kakhulu, kwaye ukuphambuka kobushushu bombala kuncinci.
Wonke umntu kufuneka akhathazeke kakhulu malunga: Yeyiphi eyona nto ingcono kwi-LED yokugcwalisa ukukhanya kunye ne-flash? Makhe sithelekise iingenelo kunye nokungonakali kwezi ntlobo zimbini zokuzalisa ukukhanya.
Inzuzo enkulu yesibane se-flash kukuba inokukhanyisa into ngokukhawuleza, ukwenzela ukuba ubukhali besithombe ngokukhawuleza bufike kwinqanaba eliphezulu le-lens ngaphandle kokuphambuka kombala. Ukungalungi, okokuqala, kufuneka ube nezakhono ezithile zokusebenzisa ukukhanya. Nangona zininzi izibane ze-TTL zokuvezwa okuzenzekelayo, i-TTL ezenzekelayo akwanelanga, kusafuneka uhlengahlengise imbuyekezo ye-flash exposure.
Kwaye ukukhanya okukhokelela ekukhanyeni njengenkwenkwezi ekhulayo, ineenzuzo ezininzi, sishwankathele amanqaku amathathu:
I-1.WYSIWYG igcwalise umphumo wokukhanya, kulula ukuyisebenzisa, nokuba akukho siseko sokufota kunye nokukhanya, inokusetyenziswa kwakhona, kwaye akukho mfuneko yokulinda i-callback, ekulungele ngakumbi xa ubamba. Yintoni onokuyijonga ngesibane esikhanyayo ayaziwa de i-shutter icinezelwe, kwaye kukho ixesha lokulinda le-0.2-10 imizuzwana.
2. Umgangatho wokukhanya uthambile. Ngokomgangatho wokukhanya, ukukhanya kunye nobumnyama bomthombo wokukhanya kunokulungiswa nangaliphi na ixesha. Umthombo wokukhanya wokukhanya kwe-LED uthambile kunokukhanya kwe-flash, kwaye akukho mfuneko yokufakela isigubungelo sokukhanya okuthambileyo okanye i-accessory yokukhanya ye-ambrela yokukhanya xa udubula. Umthombo wokukhanya wesibane unamandla amakhulu okuphuma kwaye ukukhanya kukukhanya okunzima kakhulu. Ngoko ke, kwi-portrait shooting, i-flash idla ngokudutyulwa ngokudanyaza (intloko yesibane ikhanya ngokubhekiselele kwisilingi emhlophe kunye nokukhutshwa kodonga). Ukudanyaza ngokuthe ngqo kunokuchaphazela amehlo omntwana wakho, ngoko musa ukuyenza loo nto emntwaneni ongekapheli nonyaka ubudala.
I-3.Ugxininiso lusenokuphunyezwa ngokulula ngokukhanya okuphantsi. Kwiindawo eziphantsi kokukhanya, ukusetyenziswa kwe-LED yokuzalisa ukukhanya kunokunyusa izinga lokukhanya kwe-ambient ngokuqhubekayo ngokuzalisa ukukhanya, kwaye wenze ikhamera ibe lula ukugqiba umsebenzi ogxininisekileyo, endaweni yokusebenzisa isibane sombane, kubangela ukukhanya okunganeleyo xa kugxininisekile.
Ekudubuleni ubomi, ukukhanya kwe-flash kunzima kakhulu, ngokuqhelekileyo kusetyenziswa i-lighter led fill light.Izibane zokufota ezikhokelwayo zingabonisa ngokucacileyo iinkcukacha, ngelixa zidlula ubunzulu bolawulo lwentsimi, zenze umfanekiso ubekwe.
Ukuphuhliswa kwezibane zokufota ze-LED kuye kwaba lukhetho oluyimfuneko kwiifilimu ezininzi zobuchwephesha, iimagazini kunye neenkampani zentengiso.
