Buyela ku-Basics Photography: Ngokujula Bheka i-ISO

Buyela ku-Basics Photography: Bheka Ngokujulile i-ISO

Ezinyangeni ezizayo uJohn J. Pacetti, i-CPP, i-AFP, uzobe ebhala uchungechunge lwezifundo eziyisisekelo zokuthatha izithombe.  Ukubathola bonke vele useshe “Buyela kuzinsisekelo”Kubhulogi lethu. Lo ngumbhalo wesithathu kulolu chungechunge. UJohn uyisivakashi esivamile e I-MCP Facebook Community Group. Qiniseka ukuthi ujoyina - kumahhala futhi kunemininingwane eminingi kakhulu.

Esihlokweni sethu sokugcina ngikubheke unxantathu wokuchayeka. Ngalesi sikhathi sizojula nge-ISO.

ISO ukuzwela kwenzwa. Inzwa iqoqa ukukhanya. Ukukhanya kwenzwa yikhona okwenza isithombe sakho. Ukwehla kwenombolo ye-ISO kuyadingeka kakhulu ukukhanya ukudala isithombe, izigcawu ezikhanyayo. Ukuphakama kwenombolo ye-ISO ukukhanya okuncane kuyadingeka ukwenza isithombe, izigcawu ezimnyama.

Ukwazi ukuthi i-ISO ibonakala ikuphi, ngombono wami, ukugeja okuqondwa kakhulu kwezingxenye ezintathu ze- unxantathu wokuchayeka. Uma unenkinga ngalokhu, awuwedwa. Emuva ngosuku lwamafilimu, abantu abaningi bakhetha isivinini sefilimu esingu-100 noma esingu-400. Utshelwe ukuthi usebenzise i-100 ngaphandle nangaphandle kwe-400. Lokhu kuseyiqiniso namanje. Amakhamera anamuhla edijithali, kepha asinikeza uhla lwe-ISO olukhulu kakhulu kunefilimu eyake yakwenza. Iningi lekhamera edijithali izokunikeza uhla olungu-100 kuye ku-3200 nangaphezulu. Amanye amakhamera amasha afinyelela ku-102400.

I-ISO yilokho engivame ukusetha kuqala lapho kunqunywa izilungiselelo zami zokuvezwa. Nazi izimo ezimbalwa.

• Ngenkathi ngisebenza ngaphandle, ngokwesibonelo, ipaki elinomshado womshado noma iseshini ye-portrait, iseshini yokubandakanya noma iseshini yomndeni, angidingi i-ISO ephezulu. Ngizosebenzisa i-100. Isikhathi kuphela engingakhetha ngaso i-200 uma sekuphele isikhathi sokusakaza noma sokusondela kokuhwalala lapho ngingahle ngidinge ukuzwela okuthe xaxa ekukhanyeni ukuze ngithole ukutholakala kwami ​​okuhle.
• Manje, uma ngisebenza esimweni sokukhanya okuphansi, ngokwesibonelo, isonto elingavumeli ukuthwebula izithombe, ngizokhetha i-ISO ka-800, 1600, engaba ngu-2500. Ngidinga ukuzwela kwenzwa ukuthi kube ngaphezulu. Ukuzwela okuphezulu kwenzwa kuzongivumela ukuthi ngigcine i-F-Stop ne-SS yami lapho ngifuna ukuthi badale ukuvezwa kwami ​​okuhle kuleso simo sokukhanyisa.
• Ake sithi ngifuna ukusebenza ngokukhanya kwefasitela okutholakalayo. Ukukhanya kwewindi kuhlakazekile (ikakhulukazi) ukukhanya kwelanga. Ngizohamba nama-400 cishe angu-800 uma ukukhanya kungagcini ngokwanele njengosuku olunamafu. Futhi, ukusetha i-F-Stop ne-SS yami uma sengine-ISO yami.

Ukuphindaphinda okuncane: Sebenzisa i-ISO ephansi ezimweni ezikhanyayo (100). Ezimweni zokukhanya okuphansi, sebenzisa i-ISO ephakeme (400, 800, 1600). Lapho usuthathe isinqumo nge-ISO yakho, ungakwazi ukusetha i-SS ne-F-Stop yakho.

Ngiyethemba ukuthi lokhu kukunikeza umbono ongcono wokuthi i-ISO isebenza kanjani nokuthi ungayisebenzisa kanjani i-ISO ukuze izuze wena. Imfundo ingukhiye. Lapho usuthole leyo mfundo, awunakumiswa umsebenzi onomvuzo wokuthatha izithombe. Imfundo ayipheli, akekho noyedwa umuntu owazi konke.

Ngokuzayo sizobheka i-F-Stop.
