Back to Basics Photography: Momwe Shutter Speed ​​Imakhudzira Chiwonetsero

M'miyezi ikubwerayi a John J. Pacetti, CPP, AFP, azilemba mndandanda wamaphunziro oyambira kujambula.  Kuti muwapeze onse ingofufuzani "Bwererani ku Zowona”Pabulogu yathu. Iyi ndi nkhani yachisanu ndi chimodzi mndandandawu. John amakonda kuchezera alendo ku MCP Facebook Gulu Gulu. Onetsetsani kuti mulowe - ndiulere ndipo ali ndi zambiri zambiri.

Munkhani yathu yomaliza tikuwona momwe F-Stop idakhudzira kuwonekera. Nthawi ino tiwona momwe Kuthamanga Kwachangu kumakhudzira kuwonekera.

Kuthamanga kwa Shutter ndi chiyani?

Kuthamanga kwa Shutter ndi nthawi yomwe shutter imatsegulidwa, kulola kuti kuwala kufikire pa sensa. Kuwala kukakhala nthawi yayitali pa chithunzicho, chithunzicho chimawonekera kwambiri. Kuchuluka kwa nthawi yomwe kuwala kuli pa sensa, zithunzithunzi zakuda kapena zochepa zidzawonekera. Apa ndipomwe mbali zina ziwiri zamakona atatu obwera zimabwera kuti ziwoneke bwino, kuti zithunzi zanu ziziwululidwa bwino, osazionetsera kapena kuziwulula.

Nazi zinthu zina zingapo zofunika kuzidziwa ponena za Shutter Speed ​​(SS):

• Mofulumira SS iziziritsa kanthu, 1/125 kapena kupitilira apo.
• Pang'onopang'ono SS iwonetsa kuyenda, 1/30 kapena pang'onopang'ono.
• Kugwira kamera yanu pang'onopang'ono SS nthawi zambiri kumakhala kovuta kwa anthu ambiri. Maulendo atatu amalimbikitsidwa kwa SS pa 1/15 ndipo pang'onopang'ono, ngakhale 1/30.

Zonse zomwe zikunenedwa, monga ndanenera m'nkhani yapita, nthawi zambiri ndimakhazikitsa ISO ndi F-Stop koyamba nthawi zambiri. Popeza tikukambirana za SS pano, sitikamba za F-Stop kapena ISO pompano. Amanyalanyaza kwathunthu.

Nthawi yogwiritsa ntchito FAST Shutter Speed ​​...

Pali zowunikira pomwe ndikufuna SS yachangu. Mwachitsanzo: Ndikujambula zochitika zamasewera pomwe ndikufuna kuzimitsa zochita, ndiye kuti ndikufunika SS 1/125 kapena kupitilira apo kuti ndiimitse zomwezo. Nditha kukhala pamalo owunikira pomwe ndili munthawi yowala kwambiri; Kuti ndiwonetsedwe kapena kuwoneka ndikufuna chithunzichi, ndikufuna liwiro lakutsekera. Mwinamwake chithunzi cha m'mphepete mwa nyanja kapena dzuwa lotseguka.

Nthawi yogwiritsa ntchito SLOW Shutter Speed…

Ndimatha kujambula zokongola, ngati kugwa kwamadzi. Nditha kufuna SS yothamanga kuti iziziritsa madzi akugwa kuti ndikwaniritse mawonekedwe owundana ndi madzi, koma ndikhoza kufuna SS yocheperako, kuti nditha kuwonetsa kayendedwe ka madzi pamalopo. Nditha kukhala ndikujambula mawonekedwe akuda kwambiri mwina owoneka bwino tsiku losatentha. Kuti ndikwaniritse mawonekedwe omwe ndikufuna ndikufunika katatu ndi SS yocheperako. Ndimatha kujambula dzuwa likulowa kapena kutuluka. Kuwala kukusintha mwachangu ndipo mwina ndingafunike kuyamba ndi SS yocheperako ndikuwonjezeka powonekera bwino.

Kubwereza:

• Slow Shutter Speed ​​imathandizira kuyatsa mu kamera yanu ndipo imatha kuwonetsa kuyenda ngati SS yanu ikuchedwa.
• SS yapamwamba imalola kuwala kochepa mu kamera yanu ndipo imazizira kanthu.

Izi ndi zochepa chabe momwe mungafunikire kukhazikitsa kapena kusintha SS yanu. Pitani ndi kukachita. Khalani bwino. Chotsatira cha mndandandawu tiona china chimodzi tisanachimange pamodzi.
