Iyini ilensi engahlanekezeli?

Ilensi engahlanekezeli, njengoba negama liphakamisa, ilensi engenakho ukuhlanekezela komumo (ukuhlanekezela) ezithombeni ezithwetshulwe ilensi. Enqubweni yangempela yokuklama ilensi yokubona,amalensi angenawo ukuphazamisekazinzima kakhulu ukuzithola.

Njengamanje, izinhlobo ezahlukene zamalensi, njengeama-lens abanzi, ama-telephoto lens, njll., ngokuvamile anezinga elithile lokuhlanekezela ekwakhiweni kwawo.

Isibonelo, kumalensi e-engeli ebanzi, ukuhlanekezela okuvamile ukuhlanekezela "okumise okwe-pillow" ngokunwetshwa konqenqema noma ukuhlanekezela "okumise okomgqomo" ngokukhuliswa okuphakathi; Kumalensi e-telephoto, ukuhlanekezela kubonakala njengokuhlanekezela “okumise okomgqomo” ngokugoba kwangaphakathi konqenqema lwesithombe noma ukuhlanekezela “okumise okomcamelo” ngokufinyeza okumaphakathi.

Nakuba kunzima ukuzuza ilensi engahlanekezeli, amakhamera edijithali amanje angalungisa noma anciphise ukuhlanekezela ngesofthiwe eyakhelwe ngaphakathi noma ukulungiswa kwangemuva kokukhiqiza. Isithombe esibonwa umthwebuli wezithombe cishe silingana nokungahlanekezeli.

Ilensi engahlanekezeli

Yiziphi izinhlelo zokusebenza ezijwayelekile zamalensi angahlanekezeli?

Amalensi angahlanekezeliinganikeza imiphumela ephezulu, engokoqobo yokucabanga futhi isetshenziswa kabanzi emikhakheni eminingi. Ake sibheke ezinye izimo zohlelo lokusebenza ezijwayelekile zamalensi angahlanekezeli:

Ukuma ngobudePi-hotography

Amalensi angahlanekezeli angagwema ukuhlanekezelwa kwesimo sobuso babantu, ikakhulukazi uma uthwebula izithombe ezisondele kakhulu ezinomphumela onamandla wezinhlangothi ezintathu. Amalensi angahlanekezeli angabuyisela isimo sangempela sobuso babantu, enze isithombe sibe ngokwemvelo futhi sinembe.

Isithombe se-Architectural

Uma uthwebula izakhiwo, ukusebenzisa i-lens-free lens kungavimbela ngokuphumelelayo imigqa yesakhiwo ekugobeni, okwenza imigqa eqondile esithombeni ibe mncane futhi iphelele. Ikakhulukazi uma udubula izakhiwo eziphakeme kakhulu, amabhuloho nezinye izakhiwo, umphumela ungcono uma usebenzisa i-lens-free lens.

Izithombe Zezemidlalo

Emiqhudelwaneni yezemidlalo yokudubula, amalensi angahlanekezeli angaqinisekisa ukuthi abasubathi nezindawo ezisesithombeni zisesilinganisweni esinembile futhi zinemimo ephelele, futhi zingagwema imiphumela engabonakali engokoqobo ebangelwa ukuhlanekezelwa kwamalensi.

Izinhlelo zokusebenza zamalensi angahlanekezeli

EzohweboAukukhangisa

Lapho uthwebula izikhangiso zomkhiqizo, usebenzisa iilensi engahlanekezeliingaqinisekisa ukuthi ukwakheka komkhiqizo kuboniswa ngendlela efanele ngaphandle kokuhlanekezela. Ngezithombe ezidinga ukukhombisa imininingwane yomkhiqizo, ukuthungwa, njll., ukuthwebula ngelensi engahlanekezeli kunezinzuzo ezinhle, okuvumela abathengi ukuthi baqonde kangcono izici zomkhiqizo.

Imephu yendawo kanye nokuzwa kude

Emkhakheni wemephu yendawo kanye nokuzwa kude, ukunemba kwesithombe kubaluleke kakhulu. Ilensi engenakho ukuhlanekezela ingaqinisekisa ukuthi indawo ebanjiwe, ukumila kwezwe nolunye ulwazi ngeke lukhubazeke noma luhlanekezelwe ngenxa yokuhlanekezelwa kwamalensi, okuqinisekisa ukunemba kwesithombe.

SisayensiRcinga

Kweminye imikhakha yocwaningo lwesayensi edinga ikhwalithi ephezulu kakhulu yesithombe, amalensi angahlanekezeli angasetshenziswa futhi njengesisetshenziswa esibalulekile sokubheka nokurekhoda izigigaba nedatha phakathi nokuhlolwa ukuze kuqinisekiswe ukunemba kwemiphumela yokuhlolwa.
