Ngati mwasokonezeka ndi "IS" yomwe ingakhale yomangidwe mpaka kumapeto kwa dzina la kamera ya digito yomwe mukuganiza, simuli nokha. IYE, ikagwiritsidwa ntchito ndi kamera yadijito, ndi yoperewera kwa "makina opanga chithunzi," zomwe zimathandiza kamera kukuthandizani kuchepetsa zithunzi zosautsa kuchokera ku kugwedeza kamera.
Ngakhale kukhazikika kwa chithunzi cha kamera sikunayambe, makamera ambiri ogwiritsira ntchito makompyuta tsopano akuphatikizapo IS technology. Pamene IS ikukula kwambiri, ndizofunika kudziwa zomwe mukugula, monga kukhazikika kwazithunzi kumapezeka muzithunzi zosiyana.
Kukonzekera kwapadera kwakukulu kwa kujambula kwajambula kamera ndi:
- Optical IS
- Digital IS
- Zachiwiri IS
Zofunikira
Mafilimu ogwirizanitsa zithunzi amagwiritsa ntchito ma hardware kapena mapulogalamu mkati mwa kamera ya digito kuti achepetse zotsatira za kugwedeza kamera kapena kugwedeza. Kusokoneza kamera kumatchulidwa kwambiri ngati mukugwiritsa ntchito lens kutalika kapena pamene mukuwombera pansi, pamene makamera a shutter lifulumira ayenera kukhala pang'onopang'ono kuti alowetse kuwala kwina kuti afike pa chithunzi cha chithunzi cha kamera. Pang'ono ndi pang'ono, kuthamanga kulikonse kapena kugwedeza kumachitika ndi kamera kumakweza, nthawizina kumachititsa zithunzi zovuta. Ngakhale kusuntha pang'ono chabe kwa dzanja lanu kapena mkono kungapangitse khungu kochepa.
IZI siingalepheretse chithunzi chilichonse chophwanyika-monga ngati nkhani ikuyenda mofulumira kwambiri pafupipafupi yomwe mumagwiritsa ntchito-koma imayenda bwino pokonza zolaula zomwe zimayambitsa kusuntha pang'ono kwa wojambula zithunzi (osamva bwino; aliyense wojambula zithunzi ali ndi vuto ili nthawizina). Owonetsa opanga IS akhoza kukulolani kuti muwombere maulendo angapo othamanga mofulumira kuposa momwe mungathere popanda IS.
Ngati mulibe kamera yomwe imapereka chithunzi chabwino chazithunzi, muyenera kuyesa kuthamanga mofulumira, zomwe zingakhale zovuta pazigawo zochepa. Yesani kuwonjezera ISO yanu ya makamera kuti muthe kuwombera mwamsanga msangamsanga wothamanga ngati kuwala kwa kamera kulibe kukupatsani zotsatira zomwe mukufuna.
Optical IS
Kwa makamera ojambulira makompyuta omwe amachitira ojambula oyamba komanso oyamba, mawonekedwe a mawonekedwe (nthawi zina amafupikitsidwa ku OIS) ndi luso lamakono la IS.
Optical IS imagwiritsira ntchito zida za hardware kuti zisawonongeke kugwedeza kamera. Wopanga aliyense ali ndi kasinthidwe kake koti azigwiritsira ntchito opanga IS, koma makamera ambiri a digito omwe ali ndi chithunzi chokhala ndi mawonekedwe amagwiritsa ntchito gyro sensor yomwe imamangidwa mu kamera yomwe imayendera kayendedwe kalikonse kuchokera kwa wojambula zithunzi. Gyro sensor imatulutsa miyeso yake mwa kukhazikika kwa microchip kwa CCD, yomwe imasintha pang'ono kubweza. CCD, kapena chipangizo chophatikizira, akulemba fanolo.
Kukonzekera kwa hardware komwe kumapezeka ndi optical IS ndiyo mawonekedwe abwino kwambiri a chithunzi chokhazikika. Sichifuna kuwonjezera mphamvu za ISO, zomwe zingasokoneze khalidwe la chithunzi.
Digital IS
Kukhazikika kwa chithunzichi kumaphatikizapo kugwiritsa ntchito mapulogalamu a pulogalamu ndi digito kuti asachepetse zotsatira za kugwedeza kamera. Kwenikweni, digito YAM'MBUYO YAM'MBUYO YOTSATIRA TUMIZANI LINKI SINDIKIZANI ILI MU KOPERANI MAPODIKASITI MITU YA NKHANI Ndikamera kamatha kulenga chithunzi kuchokera ku kuwala kochepa, kamera ikhoza kuwombera mwamsanga msangamsanga wothamanga, womwe umachepetsanso fodya kuchokera ku kugwedeza kamera.
Komabe, digito YAM'MBUYO YAM'MBUYO YOTSATIRA TUMIZANI LINKI SINDIKIZANI ILI MU KOPERANI MAPODIKASITI MITU YA NKHANI Kuwonjezereka kwa mphamvu za ISO mwa njira imeneyo kungasokoneze khalidwe la fano, kumapangitsa phokoso loposa phokoso lajambula ndi nambala iliyonse yamaphikseli osokonekera omwe salemba bwino. Mwa kuyankhula kwina, kufunsa kamera kuyesa kulenga chithunzi pa zochepa zosayenera za ISO zingathe kusokoneza khalidwe lachifaniziro, ndipo ndicho chimene digito imachita.
Makamera ena amatanthauzanso kukhazikika kwa chithunzi cha digito kulongosola pulogalamu yamakina yopanga digito yomwe imayesa kuchepetsako blur mutatha kutenga chithunzi, zofanana ndi zomwe mungachite ndi mapulogalamu okonza zithunzi pa kompyuta yanu. Mtundu uwu wa digito ndi wovuta kwambiri pakati pa mitundu yonse ya chithunzi chokhazikika, komabe.
Zachiwiri IS
Zachiwiri za ISI sizili zosavuta kuziphwanya, monga opanga amadzifotokozera mosiyana. Tsatanetsatane yowonjezereka ya chiwonetsero chazithunzi ziwiri zimaphatikizapo kuphatikiza kwa hardware kukhazikika (monga momwe zilili ndi opangira IS) ndi kuwonjezeka kwa mphamvu za ISO (zomwe zimapezeka ndi digito IS).
Nthawi zina, kugwiritsidwa ntchito kwazithunzi kumagwiritsidwa ntchito pofotokoza kuti digito ya SLR (single lens reflex) kamera imakhala ndi chithunzithunzi chokhazikika mu thupi la kamera komanso m'makina ake osinthasintha
Kugwira Ntchito Popanda IS
Makamera ena akale a digito sapereka mtundu uliwonse wa IS. Popewera kamera kugwedezeka mu kamera ya digito yomwe siimapereka chithunzi kukhazikika, yesani izi:
- Sungani kamera yanu pa katatu.
- Gwiritsani ntchito viewfinder ya kamera, osati LCD, kuti muyambe kuwombera.
- Dzikani nokha pamene mukuwombera mwa kudalira khoma kapena chitseko.
- Lembani zitsulo zanu kumbali ya thupi lanu ndi kugwira kamera ndi manja awiri.
- Pewani pafupipafupi mofulumira nthawi zonse, zomwe sizingatheke nthawi zonse.
Don & # 39; t Wopusitsidwa
Pomaliza, onetsetsani kuti mumamvetsa zomwe mukugula pakubwera kwa chithunzi mu kamera yanu yadijito. Okonza ena, makamaka omwe ali ndi mafano otsika mtengo, amagwiritsa ntchito mawu osokoneza, monga anti-blur mode kapena anti-shake technology, pofuna kubisala kuti kamera yawo ya digito siipereka IS. Makamera amenewa nthawi zambiri amangowonjezera kuthamanga kwafupipafupi kuti athetse zithunzi zosaoneka bwino, zomwe nthawi zina zimayambitsa mavuto ena, zomwe zimawononga khalidwe la zithunzi.
Monga chongowonjezera, opanga makamera ena a digito ali ndi mayina enieni a mawonekedwe a mawonekedwe opangira, kupitilira zinthu zovuta kwa shopper (ngati kuti tikusowa chisokonezo chachikulu). Mwachitsanzo, nthawi zina Nikon amagwiritsa ntchito "Kuchepetsa Kutsekemera," ndipo nthawi zina Sony amagwiritsa ntchito "Super Steady Shot" pofuna kutanthawuzira ku IS. Canon yakhazikitsa mtundu wa chithunzi chomwe chimatchulidwa kuti Wachinsinsi.
Musanagule mtundu wapadera, onetsetsani kuti dzina lake limatanthawuza opanga IS komanso osati mawonekedwe a digito. Muyenera kupeza chidziwitso pa webusaiti ya wopanga kapena kwa wogulitsa wodalirika pa sitolo yanu ya kamera.
Makamera amakono amamakono amangophatikizapo zithunzi za IS kapena zimaphatikizapo mtundu wina wa IS, choncho kupeza kamera yolondola kuti mukwaniritse zosowa zanu zazithunzi sizomwe zili zofunika kwambiri monga momwe ziyenera kukhalira zaka zambiri zapitazo. Komabe, kukhala ndi machitidwe abwino otetezera machitidwe ndi ofunika kwambiri kuti chipambidwe cha kamera yanu ya digito chikhale chofunika kwambiri kuti ndiyese kufufuza kawiri kamera yanu ili ndi mtundu wabwino kwambiri wa IS. Musaiwale kuti muyang'ane mndandanda wazithunzi za kamera ya mtundu wa chithunzi chomwe chilipo!
