1.Ingabe ilensi ene-engeli ebanzi ifanelekile kuma-portraits?

Impendulo ivame ukuba cha,amalensi ane-engeli ebanzingokuvamile azifaneleki ukuthwebula izithombe. Ilensi ene-engeli ebanzi, njengoba igama lisikisela, inombono omkhulu futhi ingafaka indawo eningi esithombeni, kodwa izophinde ibangele ukuphambuka nokuguquka kwezinhlamvu esithombeni.

Okusho ukuthi, ukusebenzisa ilensi ebanzi ukuthwebula izithombe kungonakalisa izici zobuso zabalingiswa. Isibonelo, ubukhulu bekhanda nomzimba bubukeka bukhulu, kanti imigqa yobuso nayo izonwetshwa futhi iphambukiswe. Lokhu akuyona inketho efanelekile yokuthwebula izithombe.

Uma udinga ukuthatha izithombe, kunconywa ukuthi usebenzise i-lens yobude obuphakathi nendawo noma i-telephoto ukuze ufinyelele umphumela wesithombe ongokoqobo futhi wemvelo onezinhlangothi ezintathu. Ngakho-ke, iyini ilensi ye-wide-engile efanele ukudubula?

A ilensi ene-engeli ebanziinobude obufushane bokugxila, ngokuvamile phakathi kuka-10mm no-35mm. Insimu yayo yokubuka inkulu kunalokho iso lomuntu elingakubona. Ifanele ukuthwebula ezinye izigcawu ezinabantu abaningi, izindawo ezibanzi, nezithombe ezidinga ukugcizelela ukujula kwensimu nemiphumela yokubuka.

Umfanekiso wokudubula ngelensi ebanzi

Ngenxa yombono wayo obanzi, ilensi ene-engeli ebanzi ingabamba izakhi eziningi, yenze isithombe sibe sicebile futhi sibe nesendlalelo esithe xaxa. Ilensi ene-engeli ebanzi ingaletha izinto kude naseduze esithombeni, inikeze umuzwa wokuvuleka. Ngakho-ke, amalensi ane-engeli ebanzi avame ukusetshenziselwa ukuthwebula izakhiwo, izigcawu zasemgwaqweni wedolobha, izikhala zangaphakathi, izithombe zamaqembu, kanye nezithombe zasemoyeni.

2.Umgomo wokuthatha izithombe kanye nezici zeamalensi ane-engeli ebanzi

Ukuthwebula izithombe zelensi ene-engeli ebanzi kufeza umphumela we-engeli ebanzi ngokuklama uhlelo lwelensi kanye ne-engeli yokuphrojektha yokukhanya (ngokudlulisa ukukhanya ohlelweni oluthile lwelensi, indawo ekude kakhulu ne-axis ephakathi iboniswa ku-sensor yesithombe sekhamera noma ifilimu), ngaleyo ndlela ivumela ikhamera ukuthi ithwebule ngombono obanzi. Lesi simiso sisetshenziswa kabanzi ekuthwebuleni izithombe, ekukhangiseni nakwezinye izinkambu.

Singaqonda isimiso sokuthwebula izithombe samalensi ane-engeli ebanzi kulezi zici ezilandelayo:

Uhlelo lwelensi:

Amalensi ane-engeli ebanzingokuvamile zisebenzisa inhlanganisela yobude obufushane be-focal kanye namalensi amakhulu anobubanzi. Lo mklamo uvumela ilensi ene-wide-engeli ukuthi iqoqe ukukhanya okwengeziwe futhi ikudlulisele kahle kusensa yesithombe sekhamera.

Ukulawula ukuphazamiseka:

Ngenxa yomklamo okhethekile, amalensi ane-engeli ebanzi avame ukuba nezinkinga zokuphambuka, njengokuphambuka, ukuhlakazeka, njll. Ukuze kuxazululwe lezi zinkinga, abakhiqizi basebenzisa izingxenye ezahlukene ze-optical kanye nobuchwepheshe bokumboza ukuze banciphise noma baqede le miphumela emibi.

I-engeli yokuphrojektha:

Ilensi ene-engeli ebanzi ifinyelela umphumela we-engeli ebanzi ngokwandisa i-engeli ephakathi kwendawo kanye ne-axis ephakathi yelensi. Ngale ndlela, kuzofakwa indawo eningi esithombeni ngebanga elifanayo, okubonisa insimu ebanzi yokubuka.

Ilensi ene-engeli ebanzi

Ezindleleni ezisebenzayo, sidinga ukukhetha ilensi ebanzi efanele ngokusekelwe ezidingweni ezithile zezithombe kanye nezigcawu. Ngokuvamile, izici zokuthatha izithombe zamalensi ebanzi yilezi ezilandelayo:

Ukuhlanekezelwa kombono:

Uma udubula izinto eziseduze nge-ilensi ene-engeli ebanzi, kwenzeka ukuphambuka kombono, okusho ukuthi esithombeni esithwetshuliwe, izinto eziseduze zizobonakala zinkulu, kuyilapho izinto ezikude zizobonakala zincane. Umphumela wokuphambuka kombono ungasetshenziswa ukudala umphumela obonakalayo oyingqayizivele, njengokweqisa umbono nokugcizelela izinto zangaphambili.

Inkundla ebanzi yokubuka:

Ilensi ene-engeli ebanzi ingathwebula indawo ebanzi yokubuka futhi ingathwebula indawo noma izigcawu eziningi. Ngakho-ke, amalensi ane-engeli ebanzi avame ukusetshenziselwa ukuthwebula izigcawu ezifana nezindawo, izakhiwo, ngaphakathi endlini, kanye nezixuku ezidinga ukukhombisa umuzwa wendawo ebanzi.

Imiphetho egobile:

Amalensi ane-engeli ebanzi avame ukuphambuka komphetho noma imiphumela egobile, ikakhulukazi emaphethelweni avundlile naqondile. Lokhu kungenxa yokulinganiselwa okungokwenyama komklamo welensi futhi ngezinye izikhathi kungasetshenziswa ukudala ngamabomu umphumela okhethekile noma ulimi olubonakalayo.

Ukujula kwensimu okunwetshiwe:

Ilensi ene-engeli ebanzi inobude obuncane bokugxila, ngakho-ke ingakhiqiza ukujula okukhulu kwensimu, okungukuthi, kokubili indawo yangaphambili neyangemuva ingagcina isithombe sicacile. Lesi sici senzaamalensi ane-engeli ebanziiwusizo kakhulu ezithombeni lapho ukujula okuphelele kwesigcawu kudingeka kugcizelelwe khona.
