Buyela ku-Basics Photography: Shutter Speed ​​Ithinta Kanjani Ukuvezwa

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 wesithupha kulolu chungechunge. UJohn uyisivakashi esivamile e I-MCP Facebook Community Group. Qiniseka ukuthi ujoyina - kumahhala futhi kunemininingwane eminingi kakhulu.

Esihlokweni sethu sokugcina sibheka ukuthi i-F-Stop ikuthinte kanjani ukuvezwa. Ngalesi sikhathi sizobheka ukuthi isivinini sokuvala sikuthinta kanjani ukuvezwa.

Yini iSivinini Shutter?

Ijubane le-Shutter yisikhathi lapho i-shutter ivulekile, ivumela ukukhanya ukuthi kufinyelele enzwa. Ukukhanya okuhlala isikhathi eside kunzwa kuzocaca noma kuvezwe kakhudlwana isithombe. Isikhathi esincane lapho ukukhanya kuku-sensor, izithombe zizovezwa mnyama noma kancane. Yilapho ezinye izingxenye ezimbili zonxantathu zokuchayeka zingena khona ukuze zivezwe kahle, ukuze izithombe zakho zivezwe kahle, kungabi ngaphezulu noma ngaphansi kokuvezwa.

Nazi ezinye izinto ezimbalwa okufanele wazi mayelana neShutter Speed ​​(SS):

• I-SS esheshayo izomisa isenzo, 1/125 noma ngaphezulu.
• ISlower SS izokhombisa ukunyakaza, 1/30 noma kancane.
• Ukubamba ikhamera yakho nge-SS ehamba kancane kuvame ukuba nzima kubantu abaningi. Kunconywa i-tripod ye-SS ngo-1/15 futhi ihamba kancane, noma i-1/30.

Konke okushiwoyo, njengoba bengishilo ku-athikili edlule, ngivame ukusetha i-ISO yami ne-F-Stop kuqala ezimeni eziningi. Njengoba sixoxa nge-SS lapha, ngeke sikhulume nge-F-Stop noma nge-ISO njengamanje. Ungabanaki ngokuphelele.

Ungasisebenzisa nini isivinini se-FAST Shutter…

Kunesimo sokukhanyisa lapho ngifuna khona i-SS esheshayo. Isibonelo: ngithwebula umcimbi wezemidlalo lapho ngifuna ukufriza isenzo ngakho-ke, ngizodinga i-SS 1/125 esheshayo noma engaphezulu ukuze ngifrize leso senzo. Ngingaba sesimweni sokukhanyisa lapho ngisesimweni esikhanya kakhulu; Ukuze ngithole ukuvezwa noma ukubukeka engikufunayo emfanekisweni, ngifuna isivinini se-shutter esiphezulu. Mhlawumbe isithombe sasolwandle noma ilanga elivulekile.

Ungasisebenzisa nini isivinini se-SLOW Shutter…

Ngingahle ngithwebule isithombe esihle, njengokuwa kwamanzi. Ngingahle ngifune i-SS esheshayo ukumisa amanzi ekwindla ukufeza ukubukeka okubandayo kweqhwa ekuweni kwamanzi, kepha ngingahle ngifune i-SS ehamba kancane, ukuze ngikhombise ukunyakaza noma ukunyakaza kwamanzi endaweni yesehlakalo. Ngingahle ngithwebule isithombe esimnyama okungenzeka sibe sendawo enhle futhi, ngosuku olugubuzele. Ukufeza ukubukeka kwesithombe engisifunayo ngingahle ngidinge i-tripod ne-SS ehamba kancane. Kungenzeka ukuthi ngithwebula isithombe ukushona kwelanga noma ukuphuma kwelanga. Ukukhanya kuguquka ngokushesha futhi kungadingeka ukuthi ngiqale nge-SS ehamba kancane bese ngiyanda njengoba indawo iya ngokukhanya.

I-Recap:

• Isivinini seSlow Shutter sivumela ukukhanya okwengeziwe kukhamera yakho futhi singakhombisa ukunyakaza uma i-SS yakho ihamba kancane.
• I-SS ephakeme izovumela ukukhanya okuncane kukhamera yakho futhi kuzomisa isenzo.

Lezi yizimo ezimbalwa lapho uzodinga ukusetha noma ulungise i-SS yakho. Phuma uzilolonge. Ukuzilolonga kwenza kuphelele. Okulandelayo ochungechungeni lwezindatshana kuzobhekwa enye into ngaphambi kokuthi sihlanganise konke lokhu.

Uma unombuzo, zizwe ukhululekile ukuxhumana nami ku [i-imeyili ivikelwe]. Le imeyili iya ocingweni lwami ukuze ngikwazi ukuphendula ngokushesha. Ngingajabula ukusiza nganoma iyiphi indlela engingasiza ngayo.
