Ilensi yokugxila ende ingenye yezinhlobo ezijwayelekile zamalensi ezithombeni, njengoba inganikeza ukukhuliswa okukhulu kanye nekhono lokudubula lebanga elide ekhamera ngenxa yobude bayo bokugxila okude.

Yini ubude i-focal lens ilungele ukudubula?

Ilensi yokugxila ende ingathwebula indawo enemininingwane ekude, ifanele izigcawu zokudubula namatimu adinga ukusondeza kuzihloko ezikude. Isetshenziswa kakhulu ezithombeni zezilwane zasendle, imisebenzi yezemidlalo, izithombe ezikude, nezinye izigcawu.

1.Izithombe Zezilwane Zasendle

Ezithombeni zezilwane zasendle, ilensi ende yokugxila ivumela umthwebuli wezithombe ukuthi athwebule izikhathi ezijabulisayo zezilwane zasendle kuyilapho egcina ibanga elithile eliphephile. Ingakusiza ukuthi ugcwalise isithombe, uthwebule imininingwane, futhi ugqamise izici zezilwane.

2.Izithombe Zezemidlalo

Amalensi amade agxile nawo awusizo kakhulu ekuthwebuleni abasubathi abahamba ngokushesha noma imisebenzi yezemidlalo efana nemidlalo yebhola. Kungasondeza isihloko sakho kude, kwenze umsubathi noma umdlalo ube nomthelela futhi ube namandla.

3.Ibanga elidePi-hotography

Uma ufuna ukuthwebula izintaba ezikude, amachibi, noma ezinye izindawo zemvelo, ilensi ende yokugxila ingasondeza indawo ekude, ikusize uthole izithombe ezithinta umhlaba eziningi ezinemininingwane eminingi.

4.Ukuthatha Ngobude

Nakuba engavamile ukusetshenziselwa ukuthwebula izithombe ngobude, amalensi amade agxile angasetshenziselwa ukuthwebula izithombe zebanga elide. Ukusebenzisa ilensi ye-telephoto kungathwebula izinhlamvu ezikude futhi kugqamise kangcono isihloko, kudale umphumela wokukhohlisa ohlukile wangemuva.

Umehluko phakathilonokugxileama-lens kanyemfushaneama-focal lens

Njengezinhlobo ezimbili ezihlukene zamalensi avame ukusetshenziswa endimeni yesithombe & videograph, kukhona umehluko othile phakathi kwamalensi amade agxile kanye namalensi agxile amafushane:

1.Fubude be-ocal

Ubude bokugxila belensi ende yokugxila yinde kunaleyo yelensi yokugxila emfushane, futhi ubude bokugxila bunquma i-engeli yokubuka kanye nokukhulisa ilensi. Uma ubude be-focal bubude, i-lens ingasondeza into eduze; Lapho ubude bokugxila bufushane, yilapho i-engeli yokubuka i-lens ingayithola ibe banzi. Ilensi ende yokugxila ine-engeli yokubuka encane kanye nokukhulisa okuphezulu, okungasondeza isihloko esikude futhi kuthwebule imininingwane ngokucacile. Uma kuqhathaniswa namanye amalensi, amalensi agxilile amafushane ane-engeli yokubuka ebanzi kanye nokukhulisa okuphansi, okuwenza afanelekele ukudubula izigcawu ezibanzi nezibanzi.

2.Ibanga lokudubula

Ilensi yokugxila ende ingathwebula amashothi akude futhi igxile ngokuphumelelayo ezihlokweni ezikude; Ngokuphambene nalokho, lapho udubula izinto ebangeni eliseduze, kunemikhawulo ethile kulensi ye-telephoto. Amalensi agxilile amafushane afanele ukuthwebula ibanga eliseduze, okungaba seduze nesihloko futhi anikeze indawo yokubuka enkudlwana, awenze afaneleke kakhulu izigcawu zokudubula ezidinga ukuxhumana nesihloko; Ngokuphambene nalokho, ama-focal lens awafanele ukudubula izigcawu ezikude.

Umphumela wokufiphalisa ingemuva welensi yokugxila ende

3.Bokeh

Amalensi amade agxile ngokuvamile anendawo enkulu yokuvula enkulu, enganikeza ukujula kwenkambu encane, idale umphumela obonakala kakhudlwana wokufiphalisa phakathi kwesihloko nengemuva, futhi igqamisa isihloko ngokugqama. Amalensi okugxilwa kuwo amafushane avamise ukuba nokujula kwenkambu okukhudlwana futhi angabonisa imininingwane eyengeziwe yendawo, ngokuvamile ahluleke ukukhiqiza umphumela ofanayo wokufiphalisa wangemuva njengamalensi amade agxile.

4.Ukuthwebula uRay

Ngenxa yevelu yayo yokuvula enkulu, ilensi yokugxila ende ingathatha izithombe ezicacile ezimeni zokukhanya okuphansi. Amalensi okugxilwa kuwo amafushane anamanani amancane okuvula futhi angadinga isikhathi sokuchayeka esengeziwe noma asebenzise ukukhanya okuyisizayo ukudubula ngaphansi kwezimo zokukhanya okuphansi.

5.Iukuhlanekezela kwe-mage

Uma kuqhathaniswa namalensi agxilile amafushane, amalensi amade agxile kakhulu athambekele ekuhlanekeni nasezinkambu zesithombe ezingalingani, ikakhulukazi endaweni esemaphethelweni yelensi. Amalensi amafushane agxile azinzile futhi asebenza kangcono ngokuphathelene nokuhlanekezela kanye nezinkinga zenkambu yesithombe.
