Ukufunda Indlela yokusebenzisa indlela yokugxilwa kwe-DSLR yakho
Ukuba ungumntu ofudukela kwinqanaba aze adlale ikhamera kwisimo se- DSLR , kukho imimandla embalwa yokufotowa okuza ku funeka ufunde malunga nokuba ungaqala ukuphumelela ngekhamera yakho ephambili. Enye yezona zinto zidibanisa kakhulu xa ufanele usebenzise ukugxilwa kwimiyalelo, ngokubhekiselele xa kulungele ukusebenzisa imodi yokugxilwa kwemoto.
Ukuze ufunde kabanzi malunga neengxoxo zengqondo ngokubhekiselele ekujoliswe kuyo, funda izicwangciso ezingezantsi.
Imodi yokugxilwa ngokuzenzekelayo yilapho ikhamera ikhetha ukugxila ngokugqithiseleyo, isebenzisa iinzwa ezizinikezelwe ukulinganisa ukujoliswa kwendawo. Kwimodi ye-autofocus, umfaki-zithombe akafanele enze nantoni na.
Shutter Lag
Nangona i- shutter lag ihlala ingancinci nekhamera ye-DSLR, umgangatho wendlela yokujonga ngokuzenzekelayo iyakwazi ukubona ukuba i-shutter igqithise kangakanani ikhamera yakho. Xa usebenzisa i-auto-focus mode, unako ukulahla i-shutter lag ngokugxila phambili kwindawo. Cindezela inkinobho yokuvala i-halfway kwaye uyibeke kuloo ndawo kude kube yilapho ikhenkethi igxininisa kwi-camera. Emva koko cinezela inkinobho yokuvala intsalela yendlela yokurekhoda ifoto, kunye ne-shutter lag kufuneka isuswe.
Focus Focus
Ngoqwalaselo oluthile, uya kusebenzisa itende lesandla sakho sokunxele ukuya kwendebe yelensi. Emva koko sebenzisa iminwe yakho yasekhohlo ukuba ujike ngokukhawuleza intambo yokugxila kwi-DSLR lens uze umfanekiso ukhangele phambili. Ukubamba ngokufanelekileyo ikhamera yinto ebalulekileyo yokusebenzisa ukugxilwa kwesikhokelo, mhlawumbi uya kuzama ukusekela ikhamera ngelixa usebenzisa i-ring focus focus, engenza kube nzima ukudubula isithombe ngaphandle kokufuduka kancinci kwi-camera.
Xa usebenzisa ukugxilwa kwimiqondiso, unokufumana inhlanhla engcono ekuqaliseni ukuba indawo ijolise ngokugqithiseleyo ngokusebenzisa i-viewfinder, kunokusebenzisa i- screen LCD . Ukuba udubula ngaphandle kwelanga elikhanyayo, ukubamba isibuko kweso lakho kuya kukuvumela ukuba ugweme ukukhanya kwi-LCD kwesikrini, njengoko i-glare ingenza kube nzima kakhulu ukucacisa ubukhali bokugxila.
ImiGqaliselo yokugxila
Ukubona indlela ojoliswe kuyo okwangoku, cinezela inkinobho yeenkcukacha kwikhamera yakho ye-DSLR. Imodi yokugxila kufuneka iboniswe, kunye nezinye izicwangciso zekhamera, kwi-LCD. Nangona kunjalo, ukuseta kwimodi yokuqwalasela ingabonakaliswa usebenzisa i-icon okanye i-initials "AF" okanye "MF," oku kuthetha ukuba uya kufuneka uqiniseke ukuba uyaziqonda ezi zixhobo kunye neyokuqala. Unokudinga ukujonga nge-DSLR yomqondiso wokusebenzisa ukufumana iimpendulo.
Ngamanye amaxesha, ungasetha imodeli yokugxila kwilenki eguquguqukayo , ngokushenxisa umtshini, ukuhamba phakathi kokugxilwa kwezimoto kunye nokugxilwa kwezinto.
Ukugxila ngokuzenzekelayo
Ngokuxhomekeke kwimodeli ye-DSLR, kukho iindlela ezahlukeneyo zokujoliswa kwezimoto ezimele zifumaneke. I-AF-S (enye-servo) ilungile kwizifundo ezimileyo, njengoko ugxininiso lukhuni xa i-shutter icinezelwa ngaphantsi. I-AF-C (i-servo eqhubekayo) ilungele izifundo ezihambayo, njengoko ukugxilwa ngokuzenzekelayo ngokuzenzekelayo kunokulungisa. I-AF-A (auto-servo) ivumela ikhamera ukuba yikhethe ukuba yeyiphi iimodi zombini yokugxilwa kweemoto ezifanelekileyo ukusetyenziswa.
Ukugxilwa ngokuzenzekelayo kuthatha ukuba neengxaki zokusebenza ngokufanelekileyo xa isihloko kunye nemvelaphi yimibala efanayo; xa isifundo sithile sisesilangeni esicacileyo kunye naso kwezinye izithunzi; kwaye xa into ephakathi kwesihloko kunye nekhamera. Kwizo zihlandlo, tshintshela ekugxilweni kwimiqondiso.
Xa usebenzisa i-auto focus, ikhamera ngokuqhelekileyo igxininisa kwisifundo kwinqanaba lesakhelo. Nangona kunjalo, ezininzi zeekhamera ze-DSLR zikuvumela ukuba uhambise ingqwalasela. Khetha umyalelo wendawo ojoliswe kuyo kwaye uhambise iphuzu lokugxila usebenzisa izitshixo zokucoca.
Ukuba i-lens yekhamera inomtshintsho wokuhamba phakathi kokugxilwa kwesikhokelo kunye nokugxilwa kwezimoto, ngokuqhelekileyo kuya kubhalwe nge-M (incwadi) kunye ne-A (auto). Nangona kunjalo, ezinye iilensi ziquka imodeli ye-M / A, eyona nto igxininise ngokuzenzekelayo kunye nenketho engaphezulu.
