Amalensi e-Varifocalinikeza ukuguquguquka kokulungisa ubude bokugxila, ukucindezela isikhala, noma ukwandisa insimu yokubuka, ukugwema ubunzima bokushintsha amalensi njalo lapho uthwebula izindawo ngaphandle. Lapho uthwebula izindawo ngelensi ye-varifocal, ukwazi amanye amasu kungathuthukisa ngempumelelo umuzwa wokujula kanye nesimo ezithombeni zezindawo, kuthuthukise kakhulu ukuvezwa kwesithombe.
1.Khetha ubude obufanele bokugxila ngokwezidingo zakho zokudubula
Amalensi e-Varifocal akuvumela ukuthi ulungise ibanga lokudubula ngokushintsha ubude be-focal. Okokuqala, udinga ukukhetha ubude be-focal obufanele ngokusekelwe kusihloko sakho nezidingo zokwakheka, bese ubhala futhi uthwebula. Ubude be-focal obude bungagcizelela isihloko, kuyilapho ubude be-focal obufushane bufanelekela ukuthwebula izindawo ezinkulu.
Isibonelo, ukusebenzisa isethingi ye-engeli ebanzi (njenge-24mm noma emfushane) kukuvumela ukuthi uthwebule ingxenye enkulu yesigcawu, ubonise ububanzi kanye nomuzwa wesikhala; ukusebenzisa isethingi ye-telephoto (njenge-100mm noma ngaphezulu) kusondela izinto ezikude, kucindezela isikhala, futhi kugqamise imininingwane; ilensi ye-varifocal engu-24-105mm inikeza ukuguquguquka kwezimo ezahlukahlukene zokudubula.
2.Uchwepheshe wezindlela ezahlukene zokuqamba
Ingqikithi yezithombe zezwe ukwakheka. Uma uthwebula ngelensi ye-varifocal, awudingi ukuhamba; ungathuthukisa ngokushesha ukwakheka ngokulungisa ubude be-focal. Kodwa-ke, kusadingeka unake izimiso eziningana zokwakheka:
①Umthetho wokwakheka kwezintathu: Kungakhathaliseki ubude obuqondile, ungavula imigqa yegridi yekhamera bese ubeka umkhathizwe noma isihloko engxenyeni yesithathu yendlela ngaphesheya kohlaka. Beka isici esiyinhloko (njengokuphuma kwelanga, umuthi owodwa, noma isikebhe esincane) endaweni yokuhlangana kwemigqa yegridi ukuze ugweme ukuqina kokwakheka okuphakathi nendawo futhi uthuthukise ibhalansi yesithombe.
②Ukusebenzisa izakhi zangaphambili ngelensi ene-engeli ebanzi: Nakuba ilensi ene-engeli ebanzi ikuvumela ukuthi uthwebule ingxenye enkulu yesehlakalo, ingabangela kalula isithombe esiyisicefe. Ukuze ugweme lokhu, faka izakhi zangaphambili engxenyeni yesithathu engezansi yohlaka, njengamatshe, izimbali, izindlela zokuhamba zokhuni, noma izithunzi zabantu, ukuze uqondise iso lombukeli maphakathi nesizinda, weqise umuzwa wokujula kwendawo.
③Ukusebenzisa ilensi ye-telephoto ukuze kube lula izakhi zokwakheka: Uma indawo igcwele izakhi, ilensi ye-telephoto ingasetshenziswa ukukhetha ingxenye ehlaba umxhwele kakhulu, njengomuthi owodwa, indlu encane, noma isiqongo sentaba esikhanyiswa ukukhanya. Lokhu kucindezela isikhala, kwenza kube lula ukwakheka, futhi kukhishwe imininingwane.
Ukwazi amasu okuqamba kubalulekile uma uthwebula ngelensi ye-varifocal
3.Naka izilungiselelo zokukhanya kanye nokuchayeka
Ukuthwebula izithombe ngendlela yezwe ngokuvamile kudinga ukuthi kokubili ingaphambili kanye nesizinda kugxile kakhulu, ngakho-ke imbobo encane ivame ukusetshenziswa ukufeza ukujula okukhulu kwensimu, njenge-f/8, f/11, noma ngisho encane kakhulu. Kubalulekile ukuqaphela ukuthi uma usebenzisa ilensi ye-telephoto ukuthwebula izithombe eziseduze ezinemininingwane, ukusebenzisa imbobo engu-f/16 noma encane kungabangela ikhwalithi yesithombe enciphile ngenxa yemiphumela yokusabalalisa. Ngakho-ke, kufanele kulinganiswe phakathi kokujula kwensimu kanye nekhwalithi yesithombe.
Kunconywa ukulungisa amapharamitha ekhamera njenge-ISO, isivinini se-shutter, kanye nebhalansi emhlophe ngokwezimo zokukhanya ukuze kufezwe ikhwalithi yesithombe engcono kakhulu. Ekukhanyeni okukhanyayo, izinga lokusondeza eliphezulu lingasetshenziswa; ekukhanyeni okuphansi, izinga lokusondeza kufanele lincishiswe ukuze kugwenywe ukufiphala kwesithombe kanye nomsindo owandisiwe. Ukukhanya kwangaphambili noma ukukhanya okuseceleni kungaveza kangcono ukujula nobukhulu bezinto obuthathu. Ungazama ukudubula ngesikhathi samahora egolide okusa noma ukuhwalala, lapho ukukhanya kuthambile futhi imibala icebile.
4.Sebenzisa i-tripod ukuze uzinze izithombe zakho
I-tripod ingenye yezesekeli ezibaluleke kakhulu zezithombe zezwe. Ukusebenzisa i-tripod kuvimbela ngempumelelo ukufiphala okubangelwa ukushukuma kwekhamera, ikakhulukazi ezimweni zokukhanya okuphansi noma lapho usebenzisa amalensi e-telephoto. Iphinde ikuvumele ukuthi usebenzise ngokuzethemba i-ISO ephansi kanye nezimbobo ezincane ngaphandle kokukhathazeka ngesivinini se-shutter esisheshayo. I-tripod ibalulekile, ikakhulukazi ngezikhathi zegolide (ukuphuma kwelanga nokushona kwelanga) lapho ukukhanya kubuthakathaka.
Ngaphezu kwalokho, ukusebenzisa i-tripod kusiza abathwebuli bezithombe ukuthi balondoloze ukuzinza ngesikhathi sokuthwebula, ikakhulukazi lapho bethwebula izithombe ezidlula isikhathi noma bebona izithombe isikhathi eside.
I-tripod iyadingeka ukuze kudutshulwe kahle
5.Sebenzisa ama-lens hood ngendlela efanele
Amalensi e-VarifocalZivame kakhulu ukukhiqiza ukukhanya kwelensi kunezinye izinhlobo zamalensi; ngakho-ke, i-lens hood efanelekile ibalulekile. Ikakhulukazi uma uthwebula ubhekene nokukhanya noma ngokukhanya okuseceleni, ukusebenzisa i-lens hood kusiza ukunciphisa ukukhanya futhi kuthuthukisa ukungafani kwesithombe nombala.
6.Naka ukucutshungulwa kwangemva kokucubungula
Amalensi e-Varifocal, ikakhulukazi uma esetshenziswa ekugcineni kwe-wide-angle, avame ukubonisa ukuphambuka kwe-barrel kanye nokufiphaza, okungalungiswa ekucutshungulweni kwangemuva. Ukudubula ngefomethi ye-RAW kuvumela ukulungiswa ekucutshungulweni kwangemuva, njengokulola, ibhalansi emhlophe, kanye nokulungiswa kombala, okungathuthukisa kakhulu ikhwalithi yesithombe.
Ukudubula amalensi e-Varifocal kudinga ukusetshenziswa kahle kwe-lens hood
7.Zama amasu okudubula okudala
Ngemva kokwazi amasu ayisisekelo okusebenzisa amalensi e-telephoto, ungazama nezindlela zokudubula zokudala. Isibonelo, ukugxila ekuqoqeni: uma uthwebula ngelensi ene-engeli ebanzi futhi useduze kakhulu nengaphambili, ngisho nokusebenzisa imbobo encane kungase kungavumeli kokubili ingaphambili eliseduze kakhulu kanye nengemuva elikude kakhulu ukuthi ligxile.
Kulesi simo, ungagxila ezindaweni ezahlukene ebangeni elihlukile bese uthatha izithombe eziningi, bese usebenzisa isofthiwe ukuze uzihlanganise zibe isithombe esisodwa lapho kokubili ingaphambili nengemuva kubukhali khona.
Ngamafuphi, lapho kudutshulwa izindawo nge-ilensi ye-varifocal, abathwebuli bezithombe bangasebenzisa ukuguquguquka kwayo kanye nokuguquguquka kwayo ukuze bathwebule izigcawu ezahlukene zezwe. Ukwazi amasu athile kuzosiza ekukhiqizeni izithombe zezwe ezisezingeni eliphezulu nezobuciko.
