Ukufunda Indlela Yokusebenzisa Imodi Yokugxila Okufanele Nge-DSLR yakho
Uma ungumuntu othutha ukusuka iphuzu bese udubula ikhamera kumodeli we- DSLR , kunezici ezimbalwa zezithombe ozodingeka ufunde ngazo ngaphambi kokuba uqale ukuphumelela ngekhamera yakho ephakeme. Esinye sezici ezididayo kakhulu zingase zihlolwe lapho kufanele usebenzise ukugxila komuntu, uma kuqhathaniswa nokuthi kungcono ukusebenzisa imodi yokugxila kwezimoto.
Ukuze ufunde kabanzi mayelana nenkulumo-mpikiswano yokugxila kwezimoto ngokubhekisisa komuntu, funda amathiphu angezansi.
Imodi yokugxila ngokuzenzakalela yilapho ikhamera inquma ukugxila okugqamile, isebenzisa izinzwa ezizinikele ekulinganiseni ukugxila kwendawo. Kumodi ye-autofocus, umthwebuli wezithombe akudingeki enze lutho.
I-Shutter Lag
Nakuba i- shutter lag ngokuvamile ayincane ngekhamera ye-DSLR, ikhwalithi yendlela yokugxila kwezimoto inganquma ukuthi ngabe i-shutter igxile kangakanani ikhamera yakho izobona. Uma usebenzisa imodi yokugxila kwezimoto, ungakwazi ukunganaki i-shutter ngokugxila esiteji. Vele ucindezela inkinobho ye-shutter isigamu bese uyibamba kuleso simo kuze kube yilapho ikhamera igxile ekugxilweni kwekhamera. Bese ucindezela inkinobho ye-shutter insalela yendlela yokurekhoda isithombe, futhi i-shutter lag kufanele isuswe.
Ukugxila kweMibhalo
Ngokugxila okubalulekile, uzosebenzisa isandla sesandla sakho sobunxele ukuze ukhethe indebe. Bese sebenzisa iminwe yakho yesokunxele ukushintsha kancane indandatho yokugxila ku-lens DSLR kuze kube yilapho isithombe sigxile kakhulu. Ukubamba ikhamera ngokufanele kuyisici esibalulekile sokusebenzisa ukugxila kwebhuku, ngaphandle kwalokho uzozama ukusekela ikhamera ngenkathi usebenzisa i-ring focus focus, okungenza kube nzima ukudubula isithombe ngaphandle kokufiphaza kancane kusuka ekubanjeni kwekhamera.
Uma usebenzisa ukugxila kokubhaliwe, ungase ube nenhlanhla engcono ukuthola ukuthi isimo sibheke ngokuqondile ngokusebenzisa i-viewfinder, kunokusebenzisa isikrini se-LCD . Uma udubula ngaphandle kwelanga elikhanyayo, ukubamba isikhangiso ngeso lakho kuzokuvumela ukuba ugweme ukukhanya kwekrini kwesikrini se-LCD, njengoba i-glare ingenza kube nzima kakhulu ukucacisa ubukhali bokugxila.
Amamodeli wokugxila
Ukuze ubone ukuthi iyiphi imodi yokugxila okhona manje, cindezela inkinobho Ulwazi ku ikhamera yakho ye-DSLR. Imodi yokugxila kufanele iboniswe, kanye nezinye izilungiselelo zekhamera, ku-LCD. Noma kunjalo, ukulungiselelwa kwemodi yokugxila kungaboniswa besebenzisa isithonjana noma ama-initials "AF" noma "MF," okusho ukuthi uzodinga ukuqinisekisa ukuthi uyaqonda lezi zithombe neziqalo. Kungase kudingeke ubheke umhlahlandlela womsebenzisi we-DSLR ukuthola izimpendulo.
Ngezinye izikhathi, ungasetha imodi yokugxila kumalensi angashintshashintshayo , ngokuhambisa umshini, ukuhamba phakathi kokugxila kokuzenzakalela nokugxila komuntu.
I-Auto Focus
Kuye ngesimo se-DSLR, izindlela ezimbalwa ezihlukile zokugxila kwezimoto kufanele zitholakale. I-AF-S (i-single-servo) inhle ngezifundo ezimileyo, njengoba ukugxila kugcina lapho i-shutter icindezelwa eceleni. I-AF-C (i-servo eqhubekayo) inhle ngezihloko ezihambayo, njengoba ukugxila ngokuzenzakalelayo kungaguquguquka njalo. I-AF-A (auto-servo) ivumela ikhamera ukuba ikhethe ukuthi yiyiphi indlela yokuzimisela kokubili okumele isebenziseke kakhulu.
Ukugxila ngokuzenzakalelayo kubonakala kunenkinga yokusebenza kahle uma isihloko nesizinda kungumbala ofanayo; lapho isihloko siyingxenye elangeni elikhanyayo futhi ingxenye emathunzini; futhi uma into ephakathi kwesihloko nekhamera. Kulezo zimo, shintsha ekugxilweni komuntu.
Uma usebenzisa i-auto focus, ikhamera evame ukugxila kule ndaba phakathi nendawo. Noma kunjalo, amakhomera amaningi e-DSLR akuvumela ukuba uhambise iphuzu lokugxila. Khetha umyalo we-auto focus focus bese uhambisa iphuzu lokugxila usebenzisa okhiye bomcibisholo.
Uma i-lens yekhamera inomshini wokuhamba phakathi kokugxila kwebhuku nokugxila kwezimoto, ngokuvamile kuzobekwa uphawu nge-M (manual) ne-A (auto). Noma kunjalo, amanye amalensi afaka imodi ye-M / A, okugxilwe ngokuzenzakalela ngokukhetha okugxila ekugxilweni komuntu.
