I-LED Film Light uma iqhathaniswa ne-flash lamp
Ekhuluma ngamalambu ezithombe, wonke umuntu kumele ngabe wezwa nge-flash ne-led fill light. Ezithombeni zansuku zonke, kungcono ukusebenzisa ukukhanya kwe-LED noma i-flash? Kulolu shicilelo, sizokwethula izinzuzo kanye nokubi kwezinhlobo ezimbili zokukhanya kokugcwalisa izithombe ngokuningiliziwe, ukuze wonke umuntu abe nolwazi olubanzi futhi ungakhetha ukukhanya kwezithombe ezifanele kakhulu ekudalweni kokudubula.
Ake sikhulume ngokukhanya kokugcwalisa kwe-LED, lolu uhlobo lokukhanya okungaguquki, kusetshenziswa ukukhanya okuphezulu kwe-LED njengomthombo wokukhanya oyinhloko, isici esikhulu kunazo zonke ukuthi "lokho okubonayo yilokho okutholayo" gcwalisa umphumela wokukhanya. Ukusebenza okulula, ukuhlukahluka okubanzi, impilo yonke Izigcawu zokudubula zilungile, njengezithombe eziseduze, ukugcwaliswa bukhoma, ukurekhodwa kwevidiyo, ukukhanya kwasesiteji, njll. Uma nje uzizwa ufiphele, ungazisebenzisa ukuze ugcwalise ukukhanya. Okubalulekile ukuthi ishibhile.
Ngemva kokufunda ukukhanya kokugcwalisa okuholelekile, siqhubeka nokusho isibani se-flash. Uhlobo oluvame kakhulu lwesibani se-flash yi-top hot shoe flash. Kunjalo, ukukhanya okuyisilinda okufihlwe ebhokisini lokukhanya lapho uthatha isithombe nakho kuyi-flash. I-flash ukukhanya kwesithombe okuvame ukusetshenziswa kakhulu ezithombeni zomshado kanye nokuthwebula isithombe sestudiyo sesithombe. Enye yezinto ezivamile zabo futhi umehluko omkhulu kusukela ekukhanyeni okuqhubekayo, okungukuthi, amandla azoba mkhulu kakhulu, futhi ukuphambuka kokushisa kombala kuncane.
Wonke umuntu kufanele akhathazeke kakhulu ngakho: Yikuphi okungcono kokugcwalisa ukukhanya kwe-LED kanye ne-flash? Ake siqhathanise izinzuzo kanye nokubi zalezi zinhlobo ezimbili zokukhanya kokugcwalisa.
Inzuzo enkulu yesibani se-flash yukuthi singakhanyisa into ngokuphazima kweso, ukuze ubukhali besithombe bufinyelele ngokushesha izinga eliphezulu le-lens ngaphandle kokuphambuka kombala. Ukungalungi, okokuqala, udinga ukuba namakhono athile ukuze usebenzise ukukhanya. Yize kukhona ukukhanya kwe-TTL okuningi kokuchayeka okuzenzakalelayo, i-TTL ezenzakalelayo ayanele, kusadingeka ulungise isinxephezelo sokuchayeka kwe-flash.
Futhi i-led fill light njengenkanyezi ephumayo, inezinzuzo ezengeziwe, sifingqa amaphuzu amathathu:
I-1.WYSIWYG igcwalise umphumela wokukhanya, kulula ukuyisebenzisa, ngisho noma kungekho sisekelo sokuthatha izithombe nokukhanya, ingasetshenziswa futhi, futhi asikho isidingo sokulinda ukubuyisela emuva, okulula kakhulu uma uthwebula. Yini okufanele uyibuke ngesibani se-flash akwaziwa kuze kube yilapho i-shutter icindezelwa, futhi kukhona isikhathi sokulinda semizuzwana engu-0.2-10.
2. Ikhwalithi yokukhanya ithambile. Ngokwekhwalithi yokukhanya, ukukhanya nobumnyama bomthombo wokukhanya kungalungiswa noma kunini. Umthombo wokukhanya wokukhanya kwe-LED uthambile kunokukhanya kwe-flash, futhi akudingekile ngisho nokufaka isembozo sokukhanya esithambile noma isesekeli sokukhanya kwesambulela esilula lapho udubula. Umthombo wokukhanya we-flash unamandla amakhulu okukhiphayo futhi ukukhanya ngokuvamile kuwukukhanya okunzima. Ngakho-ke, ekuthwebuleni isithombe, i-flash ivame ukudutshulwa ngokuphazima (ikhanda lesibani likhanya ngokumelene nophahla olumhlophe kanye nokuphuma kodonga). Ukubaneka okuqondile kungase kuthinte amehlo engane yakho, ngakho ungakwenzi lokho enganeni engakapheli unyaka owodwa ubudala.
I-3.Ukugxila kusengafinyelelwa kalula ekukhanyeni okuphansi. Ezindaweni eziphansi zokukhanya, ukusetshenziswa kokukhanya kwe-LED kungakhuphula izinga lokukhanya elizungezile ngokuqhubekayo ngokugcwalisa ukukhanya, futhi kwenze ikhamera ibe lula ukuqedela umsebenzi wokugxila, esikhundleni sokusebenzisa isibani se-flash, okubangela ukukhanya okwanele lapho ugxila.
Ekudutshulweni kwempilo esekhona, ukukhanya kwe-flash kunzima kakhulu, ngokuvamile kusetshenziswa ukukhanya kokugcwalisa kwe-led lighter.Amalambu ezithombe eziholayo angabonisa ngokucacile imininingwane, kuyilapho edlulisa ukujula kokulawula insimu, enze isithombe sigqitshwe.
Ukuthuthukiswa kwezibani zezithombe ze-LED sekuyisinqumo esidingekayo ezinkampanini eziningi zefilimu, umagazini kanye nezokukhangisa.
