Imfihlo yokufota izithako ekufumaneni imvelaphi engacacanga

Enye yezinto endibona ukuba abafoti abaninzi bayabuzana yile, "Ndiyifumana njani loo nto imvelaphi engacacanga? Le bokeh ndiyibona kuyo yonke indawo? Yilensi yantoni eyenza loo nto? ” Ngelixa sinokuthi singasoloko sifuna imvelaphi engenantsingiselo, inokunceda ngokwenene kwiimeko apho ufuna ukubonelela ngokwahlukileyo phakathi kwesihloko (sakho) kunye nemvelaphi. Ewe ayisiyiyo ilensi ethile, kwaye zininzi izinto ezinokudlala kwimvelaphi engacacanga. Oku kunokuvakala kunzima, kodwa nje ukuba uziqonde zonke izinto, kulula kakhulu ukuqala ukufumana imvelaphi ephosakeleyo kwiifoto zakho xa ungathanda ukuba nazo.

Ingcebiso eshushu: Zonke iifoto kule bhlog ziya kuba noseto olungezantsi kwesithombe. Ifoto nganye ihlelwe kunye Ukuseta kwangaphambili kwe-MCP ukusuka kwiiseti ezahlukeneyo kwaye zonke zazifomathiwe kule bhlog kusetyenziswa i Yibonise iseti yeWebhu yeGumbi lokuKhanyisa.

Imfihlo yesithako 1: Ubunzulu bentsimi

Into yokuqala yokuyiqonda xa ufunda malunga nokufumana imvelaphi engacacanga bubunzulu bentsimi. Kukho ezinye izinto, kodwa ubunzulu bendimi (DOF) inkulu. Ubunzulu bentsimi ligama lobunzulu (ngaphambili ukuya ngasemva) kwendiza yakho ejolise kuyo. Yintoni kanye kanye inqwelo moya ejolise kuyo? Inqwelomoya ojolise kuyo lixabiso lefoto yakho ejolise kuyo, kwaye iyahambelana noluvo lwekhamera yakho (kwaye ikakhulu umphambili welensi yakho). Ngokwenyani ithiyori inyuka isihla kwaye icala liye kwicala elingenasiphelo, kodwa umphambili wayo kububanzi obungasemva, okanye ubunzulu, buphelile ngokusekwe kwezi zinto zingezantsi. Yicinge njengephepha elikhulu leglasi elinendawo eyahlukeneyo yobunzulu ngasemva ngokuxhomekeka kwizinto ezingezantsi. Zonke izinto ziyadityaniswa ukwenza ubunzulu bentsimi yefoto nganye. Ngaba uyayibona? Ewe, ngokucacileyo ngekhe ubone indawo yeglasi kwifoto yakho kodwa kwezinye iimeko ungayibona inqwelomoya ejolise ngqo efotweni, njengakumzekelo ongezantsi. Sisilayidi sokugxila kuphela.

Isithako esiyimfihlo 2: Ukuvula

ukuvuleka yenye yezinto ezichaphazela ubunzulu bentsimi. Ngokubanzi ukuvuleka kwakho (inani elincinci f), kunciphisa ubunzulu bentsimi. Oku kuthetha ukuba uya kuba nendawo encinci kakhulu ukusuka ngaphambili ukuya ngasemva kugxilwe. Kwelinye icala, ukunciphisa ukubonakala kwakho (inani elikhulu le-f), kuya kubanzi ububanzi bentsimi yakho. Uya kuba nenqwelomoya ebanzi kakhulu ukusuka ngaphambili ukuya ngasemva. Ke ilensi kwi-f8 iya kuba ne-DOF ebanzi kakhulu kune-f2.

Isithako esifihlakeleyo 3: Ubude beFocal

Okude kukude ubude obujolise kuko Iilensi zakho kwindawo ekuvulwe kuyo, kuya kubanzi ubunzulu bentsimi yakho. Ubufutshane ubude bakho ekugxilwe kubo, buyabucutha ubunzulu bentsimi. Ke ilensi kwi-24mm iya kuba nobubanzi obubanzi bentsimi kune-lens kwi-70mm, inikwe zonke ezinye izinto ziyalingana.

Imfihlo yesithako 4: Umgama ukusuka kwisifundo

Ukusondela kwakho kwisifundo sakho, kuya kuncipha ubunzulu bentsimi yakho. Okude ukude, kuya kubanzi. Ukuba ukwi-f4 nge-70mm kwaye uneenyawo ezi-4 ukusuka kwisifundo sakho, ubunzulu bentsimi buya kuncipha kakhulu kunokuba ubuku-f4 kunye ne-70mm kunye neenyawo ezili-15 kude nesifundo sakho. Esi sesona sizathu sokuba, ngeelensi ezinkulu, ubunzulu bentsimi bucekeceke kakhulu, nkqu nokukhanya okucothayo: kuba usondele kakhulu kumxholo wakho. Kumzekelo ongezantsi, bendikwi-70mm (ubude obude obude obugxile) kunye no-2.8 (indawo ebanzi; yayikutshona kwelanga kwaye ndavula ilensi yam ibanzi kangangoko ndinako ukuze ndingaphakamisi i-ISO ephezulu kakhulu). Ezi zinto zimbini zikhomba kubunzulu obuncinci bentsimi ixesha elininzi. Nangona kunjalo, izifundo zam endandigxile kuzo, abo batyibilikisi bancinci emanzini, yayiziiyadi ezilungileyo ezingama-50 kude nam, ke ubunzulu bam bentsimi babunzulu kakhulu kwaye akukho bhaxu okanye indawo ekugxilwe kuyo kwifoto ngaphandle kancinci ngaphambili.

Ezinye zeengcebiso ezilungileyo endinokukunika zona kukudlala malunga nezi zinto zintathu zokuqonda ubunzulu bentsimi. Thatha ifoto efanayo kubude obufanayo kunye nokuvula okufanayo kodwa yiya kude kwisihloko sakho ngalo lonke ixesha kwaye ubone ukuba utshintsha njani ubunzulu bendiza yakho. Okanye, thabatha ifoto efanayo kunye nobude obufanayo kunye nomgama ofanayo ukusuka kumxholo kwaye unciphise ukuvula kwakho kunye nefoto nganye. Uya kuba nakho ukubona ukuba kuninzi kangakanani ekujoliseni ngalo lonke ixesha.

Ke ngoku indinceda njani kwaye le nto ihambelana njani nemvelaphi engacacanga?

Ewe, kuqala kwinto yonke, ukuqonda ubunzulu bentsimi kuyakuvumela ukuba uqonde ukuba loluphi useto oludingayo ekufumaneni isifundo (okanye) sakho osifunayo. Kuya kufuneka uqonde ukuba inqwelomoya ojolise kuyo zii-intshi ezi-6 kuphela ububanzi kwaye unemiqolo emithathu yabantu ezinobude obuziimitha ezine, izifundo zakho azizukugxilwa kuzo zonke. Le ngcamango ibaluleke kakhulu ukuba uyiqonde. Kodwa kwakhona, kuba yonke into engekhoyo ekugxilwe kuyo ayizukujoliswa, iya kufiphala. Ke, yonke into esemva kwenqwelomoya ojolise kuyo (kwaye ngamanye amaxesha ngaphambili, kuxhomekeke kwindlela oyibeka ngayo kunye nokuba ibanzi kangakanani i-DOF yakho) iya kufiphala. Ngokubanzi ukuvuleka kwakho / ubude obude bendawo ojolise kuyo / ukufutshane nomgama wakho ukuya kwisifundo (okanye indibaniselwano yezi zintathu), kokukhona kuya kubakho ukungaboni kakuhle.

Ke, ngaba kulula oko? Akukho nto yimbi ndifuna ukuyaziWell, there is one more piece. Kwaye ukufiphala, yeyona nto ibaluleke kakhulu. Esi siqwenga umgama wesifundo sakho ngasemva.  Unokudubula kwindawo evulekileyo kunye nobude obude obude kwaye usondele kufutshane nesifundo sakho, kodwa ukuba isifundo sakho sithe ngqo eludongeni okanye etyholweni okanye nakweyiphi na into engemva kwayo, akuyi kubakho nto incinci ukhangele Kuya kufuneka ubatsalele kude kude nemvelaphi kangangoko kunokwenzeka ngenxa yokufiphala.

Kulo mzekelo, ndinezinto ezimbini kwezi zintathu ezaziseta ubungakanani obumxinwa bentsimi kwaye ndibeka inqanaba lokukhanya okuhle: ukuvula ngokubanzi kunye nobude obude obugxile. Andizange ndisondele kakhulu kuye kodwa ndinikwe ubude bam bokugxila ndandingekho kude kakhulu. Eyona nto itsalelweyo kolo fiphalo olukhulu yayikude kangakanani kunemvelaphi, nangona kunjalo; malunga neeyadi ezingama-200. Ubude obude obude bujolise ekubeni bubonakale busondele kodwa zonke ezinye izinto zinika ukufiphala okuhle.

Akusoloko ufuna ukuba nobubanzi obukhulu okanye ubude obude obugqithisileyo kwimvelaphi engacacanga, nangona. Kumzekelo wam olandelayo, othe ngqo ukusuka kwikhamera, ubude bam obufutshane bufutshane kunomzekelo wam wokugqibela, kwaye indawo yam evulekileyo iyonke inyuka ngo-7.1. Ke ndifumana njani ukungaboni kakuhle kwimvelaphi? Izinto ezimbini: enye kukuba izifundo zam (iibhotile zam zenzipho yam!) Zikude kakhulu kwimvelaphi eluhlaza. Esinye isizathu kukuba ndadubula kufutshane nezifundo zam, ziimitha ezintathu kuphela kude. Uyabona kule foto, njengefoto yasekuqaleni eposini, inqwelomoya ejolise ngqo efotweni, kwibhodi yomgangatho.

Nje ukuba ufunde zonke izinto ezifumanekayo ukuze ufumane ubumnandi obuhle bemvelaphi, iba yinto yesibini. Unokufumana ukufiphala ngokwenyani ngayo nayiphi na iilensi, nkqu neelensi zekiti, ke dlala ujikeleze nazo zonke izinto ezichazwe apha ngasentla kwaye ubone ukuba ungenza ntoni!
