Ukufota ngeDijithali eKhanya kancinci: Ukufota imifanekiso emihle kwiimeko ezinzima
Kule mihla yedijithali, ukufota kuye kwafikeleleka lula kubantu abaninzi ngokufika kweefowuni eziphathwayo kunye neekhamera zedijithali eziphambili. Ukufota ngokukhanya okuphantsi yenye yezona ndawo zithethwa kakhulu zokufota apho abafoti bafota khona imifanekiso emihle kwiimeko ezinzima zokukhanya. Njengoko iteknoloji yedijithali ihambela phambili, abafoti ngoku banezixhobo zokufota imifanekiso emihle kwiimeko eziphantsi kokukhanya.
Ukufota ngokukhanya okuphantsi kubandakanya ukufota imifanekiso kwindawo enokukhanya okuncinci kwendalo, njengasebusuku okanye kwindawo engaphakathi ekhanyisiweyo kancinci. Olu hlobo lokufota luza nemingeni eyahlukileyo, kubandakanya ukungabonakali kakuhle, ingxolo ephezulu, kunye nesidingo sokuchitha ixesha elide ukuvezwa. Nangona kunjalo, ngezixhobo kunye neendlela ezifanelekileyo zedijithali, abafoti banokufikelela kwiziphumo ezimangalisayo kwiimeko eziphantsi kokukhanya.
Enye yeendlela eziphambili zokuthatha iifoto ezisebenzisa ukukhanya okuphantsi kwedijithali kukuphuhliswa kwezakhono eziphezulu ze-ISO kwiikhamera zedijithali. I-ISO ibhekisa kubuchule bekhamera ekukhanyeni, kwaye useto oluphezulu lwe-ISO luvumela abafoti ukuba bathathe imifanekiso kwiimeko eziphantsi kokukhanya ngaphandle kokusebenzisa umthombo wokukhanya owongezelelweyo. Ngokukwazi ukuthatha iifoto kwiindawo eziphezulu ze-ISO, abafoti banokufikelela kwimifanekiso ekhanyayo necacileyo kwiindawo ezimnyama, nto leyo enciphisa isidingo sokukhanya okwenziweyo.
Ukongeza kwizakhono eziphezulu ze-ISO, iikhamera zedijithali zinetekhnoloji yokunciphisa ingxolo ephucukileyo enceda ekunciphiseni uburhabaxa kunye nengxolo yedijithali edla ngokubonakala kwimifanekiso ekhanyayo. Ezi algorithms zokunciphisa ingxolo zigcina umgangatho womfanekiso kunye neenkcukacha nakwiimeko ezinzima zokukhanya, zivumela abafoti ukuba bathathe imifanekiso ebukhali, ecacileyo kwiindawo ezikhanyayo.
Ukongeza, inkqubela phambili kubuchwepheshe be-digital sensor iphucule ukusebenza kweekhamera zedijithali kwiimeko ezikhanyisiweyo kancinci. Iikhamera ezininzi zedijithali zanamhlanje zixhotyiswe ngee-sensors ezinkulu ezibamba ukukhanya okungakumbi kwaye zivelise imifanekiso ekumgangatho ophezulu kwiimeko ezikhanyisiweyo kancinci. Ukongeza, uphuhliso lwee-back-illuminated sensors (BSI) luye lwaphucula ngakumbi ukusebenza kweekhamera zedijithali okukhanyisiweyo kancinci, nto leyo enika abafoti izixhobo zokuthwebula imifanekiso emihle nakwiindawo zokukhanya ezinzima kakhulu.
Kwicandelo lokufota ii-smartphone, amandla okusebenzisa ukukhanya okuphantsi nawo aphucuke kakhulu kwiminyaka yakutshanje. Ngokudibanisa ii-algorithms zokucubungula imifanekiso eziphambili kunye nokusebenza kweModi yasebusuku, iikhamera ze-smartphone ngoku zinokuvelisa imifanekiso enomtsalane enokukhanya okuphantsi ngaphandle kwesidingo sezixhobo ezongezelelweyo. Olu phuculo lwenze ukufota ukukhanya okuphantsi kwafikeleleka lula kubaphulaphuli abaninzi, okuvumela nabani na one-smartphone ukuba afote imifanekiso ekhangayo kwiindawo ezimnyama.
Ngokudityaniswa kwezakhono eziphezulu ze-ISO, iteknoloji yokunciphisa ingxolo kunye netekhnoloji ye-sensor ephucukileyo, ukufota ngedijithali okuphantsi kube yintsimi enomdla neguquguqukayo kubafoti. Nokuba kufota izibane zesixeko ezikhazimlayo ebusuku okanye umoya osondeleyo wesidlo sangokuhlwa esikhanyiswe ngamakhandlela, ukufota ngedijithali okuphantsi kunika amathuba angapheliyo okudala kubafoti ukuba bahlole kwaye babonise umbono wabo wobugcisa.
Njengoko iteknoloji yedijithali iqhubeka nokutshintsha, ikamva lokufota okuncinci libonakala liqaqambile kunangaphambili, linika abafoti izixhobo zokutyhala imida yobuchule kunye nokuthwebula imifanekiso emihle nakwiimeko zokukhanya ezinzima kakhulu. Imifanekiso emangalisayo.
