Buyela kwiZiseko zokuFota: Jonga ubunzulu kwi-ISO

Buyela kwiZiseko zeFoto: Ukujongwa kobunzulu kwi-ISO

Kwiinyanga ezizayo uJohn J. Pacetti, CPP, AFP, uzobe ebhala uthotho lwezifundo ezisisiseko zokufota.  Ukuzifumana zonke khangela nje "Buyela kwizinto ezisisiseko”Kwibhlog yethu. Eli linqaku lesithathu kolu ngcelele. UJohn undwendwela rhoqo e Iqela le-MCP kuFacebook. Qiniseka ukuba ujoyine-isimahla kwaye inolwazi olukhulu kakhulu.

Kwinqaku lethu lokugqibela ndikunike ukujonga unxantathu obonakalisayo. Ngeli xesha siza kungena nzulu nge-ISO.

ISO Uvakalelo lwenzwa. Inzwa iqokelela ukukhanya. Ukukhanya kwenzwa yinto eyenza umfanekiso wakho. Ezantsi inombolo ye-ISO ukukhanya ngakumbi kuyafuneka ukwenza umfanekiso, imiboniso eqaqambileyo. Ukuphakama kwenombolo ye-ISO ukukhanya okuncinci kuyadingeka ukwenza umfanekiso, iindawo ezimnyama.

Ukwazi ukuba yintoni i-ISO ebonakala ngathi ikulu, uluvo lwam, eyona mpazamo iqondakalayo kwezi ndawo zintathu ze unxantathu obonakalisayo. Ukuba unengxaki noku, awuwedwa. Buyela kusuku lwefilimu, uninzi lwabantu lukhetha isantya sefilimu esili-100 okanye sama-400. Uxelelwe ukuba usebenzise i-100 ngaphandle nangaphandle kwe-400. Oku kuyinyani nangoku. Iikhamera zedijithali zanamhlanje, nangona kunjalo zisinika uluhlu lwe-ISO olukhulu ngakumbi kunakwifilimu eyakha yenzeka. Uninzi lwekhamera yedijithali iya kukunika uluhlu lwe-100 ukuya kuma-3200 nangaphezulu. Ezinye zeekhamera ezintsha ziya phezulu njenge-102400.

I-ISO yinto endihlala ndiyibeka kuqala xa ndimisela useto lwam lokuvezwa. Nazi iimeko ezimbalwa.

• Ngelixa ndisebenza ngaphandle, umzekelo, ipaki enomtshato okanye iseshoni yomzobo, iseshoni yokuzibandakanya okanye iseshoni yosapho, andifuni i-ISO ephezulu. Ndiza kusebenzisa i-100. Ekuphela kwexesha endinokuthi ndikhethe ngalo i-200 kukuba liphelile okanye sele lisondele ngongcwalazi apho ndingadinga khona ukukhanya ngakumbi ukuze ndifumaneke kakuhle.
• Ngoku, ukuba ndisebenza kwimeko ephantsi yokukhanya, umzekelo, icawe engavumeli ukufotwa kweflash, ndiza kukhetha i-ISO engama-800, 1600, enokwenzeka ngama-2500. Uvakalelo oluphezulu lwenzwa luya kundivumela ukuba ndigcine i-F-Stop kunye ne-SS apho ndifuna ukuba benze ukubonwa kwam okuhle kuloo meko yokukhanyisa.
• Masithi ndifuna ukusebenza ngokukhanya kwefestile okukhoyo. Ukukhanya kwefestile kuyasasazeka (ubukhulu becala) ukukhanya kwelanga. Ndiza kuhamba no-400 kusenokwenzeka ukuba ngama-800 ukuba ukukhanya akunamandla ngokwaneleyo njengosuku olunamafu. Kwakhona, ukuseta i-F-Stop kunye ne-SS nje ukuba ndibene-ISO yam.

Ukuphindaphinda okuncinci: Sebenzisa i-ISO esezantsi kwiimeko ezikhanyayo (100). Kwiimeko eziphantsi zokukhanya, sebenzisa i-ISO ephezulu (400, 800, 1600). Nje ukuba uthathe isigqibo kwi-ISO yakho, unokuseta i-SS yakho kunye ne-F-Stop.

Ndiyathemba ukuba oku kukunika umbono ongcono wokuba i-ISO isebenza njani kwaye uyisebenzisa njani i-ISO kwinzuzo yakho. Imfundo ngundoqo. Nje ukuba ufumane loo mfundo, akukho nto inokumisa umsebenzi onomvuzo wokufota. Imfundo ayipheli, akukho mntu wazi yonke into.

Ngexesha elizayo siza kujonga kwi-F-Stop.
