Buyela kwiZiseko zeFoto: Isantya seShutter sichaphazela njani ukubonakalisa

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

Kwinqaku lethu lokugqibela sijonga indlela i-F-Stop echaphazele ngayo ukubonakaliswa. Ngeli xesha siza kujonga indlela iShutter Speed ​​ekuchaphazela ngayo ukubonakaliswa.

Yintoni iSantya seShutter?

Isantya seShutter lixesha lokuba ivaliwe ivulwe, ivumela ukukhanya ukuba kufikelele kwisivamvo. Okukhona ukukhanya kuhlala ixesha elide kumfanekiso oqaqambileyo okanye ocacileyo oya kuba ngumfanekiso. Ixesha elincinci lokukhanya likwi-sensor, kuya kuba mnyama okanye kancinci ukuveza imifanekiso iya kuba. Kulapho ezinye iinxalenye zontathu zonxantathu ezityhilekileyo zingena khona ukuze zibonakale ngokufanelekileyo, ukuze imifanekiso yakho ityhileke ngokufanelekileyo, kungabi ngaphezulu okanye ngaphantsi kokuvezwa.

Nazi ezinye izinto ezimbalwa ekufuneka uzazi malunga neSantya seShutter (SS):

• Ukukhawuleza kwe-SS kuya kubamba isenzo, 1/125 okanye ngaphezulu.
• Ukucotha kwe-SS kuya kubonisa intshukumo, 1/30 okanye kancinci.
• Ukubamba ikhamera yakho kancinci kwi-SS kuhlala kunzima kubantu abaninzi. Kucetyiswa i-tripod ye-SS ngo-1/15 kwaye icothe, nokuba ngu-1/30.

Konke okuthethwayo, njengoko benditshilo kwinqaku elingaphambili, bendiya kuhlala ndibeka i-ISO kunye no-F-Stop kuqala kwiimeko ezininzi. Kuba sixoxa nge-SS apha, asizukuthetha nge-F-Stop okanye nge-ISO ngoku. Ungabahoyi ngokupheleleyo.

Sisebenzisa nini iSantya sokuVala ngokukhawuleza ...

Kukho imeko yokukhanyisa apho ndifuna i-SS ekhawulezayo. Umzekelo: Ndifota umnyhadala wezemidlalo apho ndifuna ukukhenkceza isenzo ngoko, ndiyakufuna i-SS 1/125 ekhawulezayo okanye engaphezulu ukuze ndibambe isenzo. Ndingaba kwimeko yokukhanyisa apho ndikwimeko eqaqambe kakhulu; Ukuze ufumane ukubonakaliswa okanye ukujonga ndifuna kumfanekiso, ndifuna isivinini esiphezulu se-shutter. Ngokufanelekileyo umzobo wolwandle okanye ilanga elivulekileyo.

Usisebenzisa nini iSantya seShutter…

Ndingafota into entle, njengokuwa kwamanzi. Ndingafuna i-SS ekhawulezayo ukuba ifrize amanzi ekwindla ukufezekisa ukujonga okucocekileyo komkhenkce ekuweni kwamanzi, kodwa ndingafuna ukucothisa kwe-SS, ukuze ndikwazi ukubonisa intshukumo okanye intshukumo yamanzi kwindawo. Ndingafota indawo emnyama enokwenzeka kwakhona ukuba ibonakale kwakhona, ngemini eshushu. Ukufezekisa ukujonga kumfanekiso endiwufunayo ndingadinga i-tripod kunye ne-SS ecothayo. Ndingafota ukutshona kwelanga okanye ukuphuma kwelanga. Ukukhanya kuyatshintsha ngokukhawuleza kwaye kungafuneka ndiqale nge-SS ecothayo kwaye ndonyuke njengoko imeko iya ikhanya ngakumbi.

Recap:

• Isantya seShutter Slow sivumela ukukhanya ngakumbi kwikhamera yakho kwaye kunokubonisa intshukumo ukuba i-SS yakho icotha ngokwaneleyo.
• I-SS ephezulu iya kuvumela ukukhanya okuncinci kwikhamera yakho kwaye iya kubamba isenzo.

Ezi ziimeko ezimbalwa apho kuya kufuneka usete okanye uhlengahlengise i-SS yakho. Phuma uye kuziqhelanisa. Ukuzinononga kwenza ugqibelele. Oku kulandelayo kuthotho lwamanqaku kuya kujonga enye into ngaphambi kokuba sidibanise yonke le nto.
