Xa wenza ukutshintshwa ukusuka kwindawo kwaye uphendule ikhamera ukuya kwi-DSLRs, enye into ye-DSLR engadidekiyo ibona ixesha lokusebenzisa iindlela ezahlukeneyo zekhamera. Ngaphandle kwendlela yokuvala i-shutter, ikhamera iya kukuvumela ukuba ubeke isivinini se-shutter kwindawo ethile, kwaye ikhamera izakukhetha ezinye iisetingi (ezifana nokuvula kunye ne-ISO) ngokusekelwe kwisantya se-shutter oyikhethile.
Ijubane lokuvala isilinganisi sexesha apho umvaleli wekhamera ye-DSLR evulekile. Njengoko i-shutter ivulekile, ukukhanya okuvela kwisifundo kushaya umtshini wesithombe somfanekiso wekhamera, ukudala isithombe. Isantya sokuvala esheshayo sithetha ukuba i-shutter ivuliwe ixesha elifutshane, elithetha ukukhanya okungaphantsi kufinyelela kwisitho somfanekiso. I-speed shutter isivinini ithetha ukukhanya okufikile kufinyelela kwisixhobo somfanekiso.
Ukulinganisa xa iinjongo ezilungileyo ukusebenzisa i-shutter imodi yokuqala ingaba nzima kunokuba uyisebenzise. Zama ezi ngcebiso ukuze uqonde indlela yokujonga ukuba kulunge ukusebenzisa indlela yokuphambili yokuvala kunye nokusebenzisa imilinganiselo ye-shutter ehlukeneyo.
Ukukhanya ngakumbi Kuvumela ukukhawuleza kweShutter Speeds
Ngaphandle kokukhanya kwangaphandle okukhazimulayo, ungadla ngokukhawuleza kwe-shutter speed, kuba ukukhanya okuthe xaxa kufumaneka ukubetha inzwa yesithombe ngexesha elifutshane. Ngeemeko ezikhanyayo, ufuna ukukhawuleza ukuvala isivinini, ukukhanya okwaneleyo kunokukhangela inzwa yesikrini ngelixa i-shutter ivulekile ukudala umfanekiso.
Isantya sokuvala ngokukhawuleza kubalulekile ukubamba izifundo ezikhawulezayo. Ukuba isivinini sokuvala asikhawulezi ngokwaneleyo, umxholo ohamba ngokukhawuleza ungabonakala ungacacile kwisithombe.
Yilapho i-mode yokuvala i-shutter ingaba luncedo. Ukuba udinga ukudubula isihloko esihamba ngokukhawuleza, ungasebenzisa imodare yokuphambili ye-shutter ukuseta isivinini esikhulu sokuvala isivakalisi kunokuba ikhamera inokukhetha ngokwalo ngokuzenzekelayo. Uya kuba nethuba elingcono lokubamba isithombe esicacileyo.
Ukubeka I-Shutter Mode Priority
Imodi yokubaluleka ephambili ngokuqhelekileyo imakwe nge "S" kwimodi yokudayela kwikhamera yakho ye-DSLR. Kodwa ezinye iikhamera, ezifana neeModeli zeCanon, zisebenzisa i-Tv ukubonisa indlela yokuvala eyimfuneko yokuvala. Shintsha imo yefowuni kwi "S," kwaye ikhamera iya kusetyenziswa ngendlela ehamba phambili, kodwa iya kusekela zonke izicwangciso kwisantya se-shutter oyikhethayo ngesandla. Ukuba ikhamera yakho ayinayo ifowuni yofowuni, ngezinye izihlandlo ungakhetha imodi yokuqala yokuvala kwimenyu yesikrini.
Nangona phantse yonke ikhamera ye-DSLR inemoya ephambili yokuvalela, iya kuba yinto eqhelekileyo kwiikhamera ezikhoyo ezikhoyo. Ngoko qiniseka ukuba ukhangele kwimenyu yekhamera yakho kwesikrini kule khetho.
Isantya sokuvala i-fast shutter ingaba yi-1/500 yesibini, eya kubonakala njenge 1/500 okanye 500 kwisikrini sekhamera yakho ye-DSLR. Isantya esicacileyo sokuvala isivinini sinokuba ngu-1/60 yesibini.
Ukusekela isivinini sokuvala kwi-mode yokuvala, udla ukusebenzisa iifayile ezikhokelo kwiqhosha lekhamera yeekhamera ezine, okanye unako ukusebenzisa umyalelo wokudayela. Kwimodeli yokuqala yokuvala, isivalathiso sokutshintsha isivinini ngokuqhelekileyo siya kubalwa eluhlaza kwi-LCD yekhamera kwesikrini, ngelixa ezinye izicwangciso zangoku ziya kuba zimhlophe. Njengoko utshintsha isantya se-shutter, inokutshintshwa ibomvu ukuba ikhamera ayinakudala ukubonakaliswa okusebenzisekayo kwisantya se-shutter oyikhethile, oku kuthetha ukuba unokufuna ukulungelelanisa ukubeka i-EV okanye ukwandisa i- ISO setting phambi kokuba ungasebenzisa i-shutter ekhethiweyo. ngesivinini.
Ukuqonda okukhethiweyo okukhethwa kweShutter Speed Setting Options
Njengoko ulungelelanisa izicwangciso zesantya se-shutter , mhlawumbi uza kufumana izicwangciso ezikhawulezayo eziqala kwi 1/2000 okanye 1/4000 kwaye ezinokuphela ngokukhawuleza ukuhamba kweemitha ezi-1 okanye ezimbini. Izicwangciso ziza kuba ziphantse zibe malunga nesiqingatha okanye ziphindwe kabini kwisilungiselelo sangaphambili, ukusuka kwi-1/30 ukuya kwi-1/60 ukuya ku-1/125, njalo njalo, nangona ezinye iikhamera zinika izicwangciso ezichanekileyo phakathi kwezicwangciso zesantya ezivaliweyo.
Kuya kubakho amaxesha apho ukukhwela kunye ne-shutter kuqala apho ungathanda ukusebenzisa isantya esicothayo. Ukuba uya kudubula ngesivinini esicothayo se-shutter, nantoni na / 60 okanye i-slower, mhlawumbi uya kufuneka i-tripod, i-shutter esinqununu, okanye i-bulter ye-shutter ukudubula iifoto. Kwixesha elivakalayo lokuvala i-shutter, kwanokuba isenzo sokucindezela inkinobho yokuvala idibanise iyakhambelana nekhamera ngokwaneleyo ukudala isithombe esicacileyo. Kwakhona kunzima kakhulu ukubamba ikhamera ngokukhawuleza ngesandla xa ukudubula kwisantya esicothayo, esithetha ukunyakaza kwekhamera kungabangela isithombe esincinci, ngaphandle kokuba usebenzise i-tripod .
