Indlela yokusebenzisa i-AF Points ukuqinisekisa ii-Sharp Photos
Njengoko wenza utshintsho kwikhamera yezinga lokuqala ukuya kumzekelo ophambili, njenge-DSLR, uya kufumana ukulawula okungaphezulu komfanekiso wokugqibela. Unokutshintsha ikhefu lekhamera okanye isivinini se-shutter ukutshintsha ukuvezwa kwimeko. Ukuqonda amaphuzu e-autofocus yinye iqhosha eliphambili lokuba ngu-photographer ohambileyo, njengoko unokutshintsha kakhulu imbonakalo yomfanekiso ngokutshintsha i-autofocus point.
Iikhamera ze- DSLR zanamhlanje ziza kunye neengongoma zengqwalasela, ezinokuthi zibonwe ngumbonakaliso okanye kwi-screen LCD. Ngeemakhamera ezindala ze-DSLR, ezi ngongoma zibonakala kuphela kwi-viewfinder, kodwa njenge-Live View mode ithandwa kakhulu kwiikhamera zakwa-DSLR zitsha, abavelisi banike iifoto zabafundi ithuba lokujonga ezi ngongoma zecala kwi-skrini ye-LCD okanye kwisibukeli .
Kungakhathaliseki ukuba uyazijonga phi, ezi zibizwa ngokuba yii-autofocus points, okanye ii-AF. I-DSLR inenani lala manqaku angama-autofocus, ukusuka kwii-5 ukuya kwi-77 okanye ngaphezulu ze-AF. Ukuba ufuna ukufumana ukuqonda okungcono ama-AF kunye nendlela asebenza ngayo, qhubeka ufunda!
Ziziphi ii-Autofocus Points?
Iifoto ze-Autofocus yile nto ikhamera isebenzisa ngayo ukugxila kwisifundo. Mhlawumbi uya kuzibona kuqala xa ucinezela i-shutter isigxina. Amakhamera amaninzi aya kukhupha "i-beep," kwaye ezinye zeenkcukacha ze-AF ziya kukhanyisa (ngokuphindaphindiweyo kumbala obomvu okanye obomvu) kwisibhengezo okanye kwisikrini sokubonisa. Xa i-DSLR yakho ishiywe kwi-AF ekhethiweyo, uyazi apho ikhamera ibhekiselele kuyo i-AF points.
Ukusebenzisa u-AF ngokuzenzekelayo kunokusebenza kakuhle kwiintlobo ezininzi zeefoto. Ngokomzekelo, ukuba usebenzisa ubunzulu bentsimi kwaye awuyikudubula nantoni na ehambayo, ukuvumela ikhamera ukuba ikhethe ngokuzenzekelayo amanqaku e-AF kufuneka isebenze kakuhle.
Kodwa ngezinye iindidi zezifundo, ikhamera iya kudideka ngokubhekiselele ekubhekiseleleni ekujoliseni kuyo. Ngokomzekelo, ukuba uzama ukudubula iflyflyfly kwiqabunga eneenkcukacha ezizaliswe ngokuchaseneyo, ikhamera ingayigxininisa ekuchaseni ngakumbi kumva. Oku kungakhokelela kwisifundo esiyinhloko esishiywe sikhoxisiwe, ngelixa imvelaphi ijolise kuyo. Ngoko ukukhuseleka, ngamanye amaxesha kungcono ukusebenzisa ukukhetha kweM AF.
Yintoni Yomqulu we-AF Selection?
Ukukhethwa kwe-AF ngokuqhelekileyo kuthetha ukuba unokukhetha kuphela inkcazo ye-AF enye, eya kukunika indawo echanekileyo ekujoliswe kuyo. Kufuneka ukhethe uhlobo oluchanekileyo lwenkqubo ye-AF ofuna ukuyisebenzisa ngokusebenzisa amamenyu ekhamera. Kanti ukuba ikhamera yakho ye-DSLR inokuba nekhono lokuthinta isikrini, unokukwazi ukukhetha inkcazo ye-AF ofuna ukuyisebenzisa ngokuchukumisa inxalenye yeskrini equle loo nxalenye yesimo ofuna ukuyigxila kuyo, kulula ukuyisebenzisa.
Kwaye ezinye iikhamera zanamhlanje, ezinjengeCanon EOS 7D (ezichazwe apha), zinobuchule obuqilileyo be-AF, ezikuvumela ukuba ungakhethi nje kuphela amanqaku angodwa, kodwa ukhethe iqela okanye icandelo lesithombe ekujoliswe kuyo. Iinkqubo ze-AF ziba nzima ngakumbi, ngoko ukunciphisa amathuba okuba umfaki-zithombe enze ingqalelo yakhe ingalunganga.
Ukusebenzisa iNani elikhulu leeNkcazo ze-AF
Ukuba neengongoma ezininzi ze-AF zincinci ngakumbi ukuba unqwenela ukuthatha amashishini amaninzi, okanye ukuba ufotoze iimfuyo kunye nabantwana ... bobabini abahlala behleli! Ngombolo ephakamileyo yama-AF, unganciphisa amathuba okuba umxholo ungabikho kwinqanaba lokugxila. Ukuba ubukhulu becala ama- portraits okanye imihlaba , nokuba kunjalo, uya kuba nolonwabo oluncinci lweengongoma ze-AF, njengoko unokukwazi ukulungisa izifundo zakho okanye isikhundla sakho.
