Empilweni yansuku zonke, abantu bavame ukuthembela ekuthwebuleni izithombe ukuze babhale phansi ukubukeka kwabo ngokomzimba. Kungakhathaliseki ukuthi ukwabelana ngemidiya yezenhlalo, izinjongo zokuhlonza ezisemthethweni, noma ukuphathwa kwezithombe zomuntu siqu, ubuqiniso bezithombe ezinjalo sebuyinto ehlolwa kakhulu. Kodwa-ke, ngenxa yokwehluka okukhona ezimpahleni zokukhanya kanye nezindlela zokuthatha izithombe phakathi kwamalensi ahlukahlukene, izithombe zezithombe zivame ukuba ngaphansi kwamazinga ahlukahlukene okuphambuka kwejometri kanye nokuphambuka kwe-chromatic. Lokhu kuphakamisa umbuzo obalulekile: yiluphi uhlobo lwelensi oluthwebula ngokunembile izici zobuso zomuntu zangempela?
Ukuze kuxazululwe lo mbuzo, kubalulekile ukuhlola izici zobuchwepheshe zamalensi ezithombe asetshenziswa kakhulu kanye nomthelela wawo ekumelweni kobuso. Amakhamera abheke phambili, amakhamera e-smartphone abheke ngemuva, kanye namalensi asezingeni lobuchwepheshe ahluka kakhulu ngobude obuqondile, ukubuka kwendawo, kanye namakhono okulungisa ukuhlanekezela. Isibonelo, ama-smartphone amaningi asebenzisa amalensi abheke phambili ane-engeli ebanzi ukuze andise indawo ebonakalayo ngesikhathi sokuthatha izithombe. Nakuba kunenzuzo ekusebenzeni, lo mklamo wethula ukwelula okubonakalayo okuphathelene nohlangothi—ikakhulukazi okuthinta izici zobuso eziphakathi njengekhala nebunzi—okuholela “kumphumela we-fisheye” obhalwe kahle, ohlanekezela ngokuhlelekile i-geometry yobuso futhi unciphise ukunemba kokubona.
Ngokuphambene nalokho, ilensi ejwayelekile eyinhloko enobude obuqondile obungaba ngu-50mm (uma kuqhathaniswa nezinzwa zohlaka olugcwele) ibhekwa kabanzi njengevumelana eduze nombono womuntu obonakalayo. I-engeli yayo yokubuka elinganiselayo ikhiqiza ukubukwa kwemvelo, inciphisa ukuphambuka kwendawo futhi ilondoloze izilinganiso zobuso ezinembile ngokomzimba. Ngenxa yalokho, amalensi angu-50mm asetshenziswa kakhulu ekuthwebuleni izithombe zochwepheshe, ikakhulukazi ezinhlelweni zokusebenza ezifuna ukwethembeka okuphezulu, njengezithombe zepasipoti, amaphrofayili ezemfundo, kanye nezithombe zekhanda zenkampani.
Ngaphezu kwalokho, amalensi ane-telephoto ephakathi nendawo (85mm nangaphezulu) abhekwa njengendinganiso yegolide ekudwebeni kobungcweti. Lawa malensi acindezela ukujula kwendawo ngenkathi egcina ubukhali obusuka emaphethelweni kuya emaphethelweni, eveza ukufiphala kwangemuva okujabulisayo (i-bokeh) okuhlukanisa umuntu futhi kunciphise ukuphambuka kombono. Nakuba kungelula ukuzithwebula ngenxa yensimu yawo encane yokubuka, anikeza ukunemba okuphezulu kokumelela lapho esetshenziswa ngumthwebuli wezithombe ebangeni elifanele.
Kubalulekile futhi ukuqaphela ukuthi ukukhetha ilensi kukodwa akunqumi ubuqiniso besithombe. Izinguquko ezibalulekile—kufaka phakathi ibanga lokudubula, ukucushwa kokukhanya, kanye nokucubungula ngemva kokubanjwa—zinethonya elikhulu ekubonakaleni kwangempela. Ngokukhethekile, amabanga amafushane andisa ukuphambuka kokukhulisa, ikakhulukazi ekuthathweni kwezithombe eduze kwensimu. Ukukhanya okusakazekile, okuqondiswe ngaphambili kuthuthukisa ukuthungwa kobuso kanye nesakhiwo esinezinhlangothi ezintathu ngenkathi kunciphisa izithunzi ezingase ziphambukise ukuqonda kobuso. Ngaphezu kwalokho, izithombe ezicutshungulwe kancane noma ezingahlelwanga—ezingenakho ukushelela isikhumba okunolaka, ukushintshwa kobuso, noma ukuhlelwa kombala—kungenzeka kakhulu ukuthi zilondoloze ukufana okuqondile.
Ekuphetheni, ukufeza ukumelwa kwezithombe okuthembekile kudinga okungaphezu kokulula kwezobuchwepheshe; kudinga ukukhetha okuhleliwe kwendlela. Izithombe ezithathwe kusetshenziswa amalensi ajwayelekile (isb. 50mm) noma amalensi e-telephoto aphakathi nendawo (isb. 85mm), ebangeni elifanele lokusebenza nangaphansi kwezimo zokukhanya ezilawulwayo, ziveza ukunemba okuphezulu kakhulu kokumelwa kunalezo ezitholakala ngama-selfie e-smartphone ane-angle ebanzi. Kubantu abafuna imibhalo ebonakalayo yangempela, ukukhethwa kwemishini yokukhanya efanele kanye nokunamathela ezimisweni zezithombe ezimisiwe kubalulekile.
