Kana iwe uchivhiringidzika ne "ISI" iyo inogona kutariswa kusvika pakuguma kwezita re digital kamera waunofunga, iwe hausi woga. IYE, iyo inoshandiswa nekamberi kamera, inopfupika ne "teknolojia yekusimudzira tsananguro," iyo inobvumira kamera kuti ikubatsire kuderedza mifananidzo yakajeka kubva pamusana wekhamera.
Kunyange zvazvo kukamera kwekhamera kusimbiswa hakusi itsva, makamera akawanda emakambani emagetsi zvino anosanganisira IS technology. Sezvo IS inowanda yakawanda, zvinokosha kuti uzive zvauri kutenga, sezvo kugadzikana kwechifananidzo kunowanikwa mune zvigadziriro zvishoma zvakasiyana.
Iyi mitatu yekugadzirisa kwekamera yemamera yegadziriro kugadzikana ndeyi:
- Optical IS
- Digital IS
- Dual IS
The Basics
Chimiro chekugadzirisa tekemikirini inoshandisa hardware kana software mukati me digital kamera kuti kuderedze migumisiro yekhamera inodedera kana kudengenyeka. Ikamera yekhamera inonyanya kuzivikanwa paunoshandisa kureba kwema-lens kana kuti kupfura mumamiriro ekudzivirira, apo khamera yevhavha yepamhanyi inofanira kunge iri kunonoka kuti ipe chiedza chakawedzerwa kusvika pane sensor image sensor . Nenguva shoma yokuvhara nokukurumidza, chero kudengenyeka kana kudengenyeka kunowanikwa nekamera kunokudzwa, dzimwe nguva kuchikonzera kusvibisa mifananidzo. Kunyangwe kushamwaridzana kudukusa kwechiko chako kana ruoko kunogona kukonzera tsvina shoma.
IYO haigoni kudzivirira mifananidzo yose yakajeka-yakadai sekuti nyaya inofamba zvakanyanya zvakanyanya nokuda kwekuvharidzirwa kwekuvhara kwaunoshandisa-asi inoshanda zvakanaka nekugadzirisa kubwinya kunokonzerwa nekufamba kishoma kwemufotori (hakunzwi zvakaipa; ane dambudziko iri nguva nenguva). Vagadziri vanofungidzirwa IS vanogona kukubvumira kuti ufukidze mapurisa maviri ekuvhara nokukurumidza kupfuura iwe unogona kunze kweI IS.
Kana usina kamera inopa mamiriro akanaka ekugadzikana kwehurongwa, unofanidza kuedza kupfura nekukurumidza kushamisa kasi, iyo inogona kuva yakaoma mumamiriro ekudzivirira. Edza kuwedzera kamera yako ISO yekugadzirira kuitira kuti iwe unogona kupfura nokukurumidza kushamisa nekukurumidza muzasi chiedza kana kamera yaI IS iri kuisa kwete kukupa zvaunoda.
Optical IS
Nekombikiti yemakamera yemakambani ane chinangwa chekutangira uye pakati pevamwe vatori vemifananidzo, optical image stabilization (dzimwe nguva shoma kune OIS) ndiyo inoshandiswa IS technology.
Optical IS inoshandisa hardware kugadzirisa kusazvidza kamera shake. Imwe michina inogadziriswa pakushandisa optical IS, asi yakawanda kamera makamera ane stability image stabilization inoshandisa gyro sensor yakavakwa mukhamera iyo inoyera chero kufamba kunobva kumufananidzo. Iyo gyro sensor inotumira zviyero zvayo kuburikidza nekugadzirisa microchip kusvika kuCCD, iyo inoshandura zvishoma kuti inobhadhara. ICCD, kana chikwata-coupled device, inonyora mufananidzo.
Iko hardware kururamiswa inowanikwa ne optical IS ndiyo nzira yakanyatsonaka yemufananidzo kugadzikana. Iyo haifaniri kuwedzera kuwedzera kwe ISO senzwi, iyo inogona kukanganisa kunaka kwemufananidzo.
Digital IS
Dhijitimi chimiro chekusimudzira chinosanganisira kushandisa software uye digital kamera zvirongwa kuti kuderedze migumisiro yekamera shake. Zvinonyanya kukosha, digital inowedzera ISO senzwi, iyo inoyera yekunzwisisika kwekamera kusvika kuchiedza. Nekhamera yekukwanisa kuumba mufananidzo kubva pakuderera kwechiedza, kamera inogona kupfura nokukurumidza kushamisa kasi, iyo inoderedza kusvibiswa kubva pakamera kushamwaridzana.
Zvisinei, digital inowanzosvibisa ISO senzwivhe kupfuura izvo zvinowanzogadzirirwa pane kamera zvinoreva kuti zvinofanira kunge zviri mamiriro ekudzivirira kwepfuro rakati. Kuwedzera ISO kunzwisisika nenzira iyoyo kunogona kuderedza kunaka kwechifananidzo, zvichiita kuti ruzha rukuru mumufananidzo-mutsindo ipi zvayo nhamba yemapiksesi asina kukwana asina kunyora zvakanaka. Mune mamwe mazwi, kubvunza kamera kuedza kuumba mufananidzo pane zvishoma-kupfuura-zvakakwana ISO zvirongwa zvinogona kukanganisa kunaka kwemufananidzo, uye ndizvo zvinonzi digital IS.
Mamwe makamera anotaurawo nezvekugadzirisa chimiro chechigodhi kutsanangura chikamu chepurogiramu yakagadzirwa mujeri kamera iyo inoedza kuderedza blur mushure mokutora mufananidzo, zvakafanana kune zvaungagona kuita nehudhi-editing software pakombiyuta yako. Icho chinyorwa che digital chinonyanya kushanda pakati pemhando dzose dzechimiro chekusimudzira, zvisinei.
Dual IS
Dual IS haisi nyore nyore kuvhara pasi, sezvo vadziri vatsanangura zvakasiyana. Tsanangudzo inonyanya kufanana yemhando miviri yakagadzikana inosanganisira kusanganiswa kwezvinhu zvakasimbiswa (sezvakawanikwa ne optical IS) uye kuwedzera ISO senzwi (sekuwanikwa ne digital digital).
Dzimwe nguva, zviviri zvakagadzirika mufananidzo zvinoshandiswa kurondedzera chokwadi chokuti digital SLR (single single lens reflex) kamera ine chinyorwa chekusimudzira teknolojia mune zvose mumuviri wekhamera uye mumashandisi ayo akachinja
Kushanda pasina IS
Mamwe makamera emakemikari ekare haapi kupa rudzi rweI. Kuchengetedza kamera kushungurudza mune imwe kamera kamera iyo isina kupa chimiro chekusimudzira, edza mazano aya:
- Gadzira kamera yako pane imwe katatu.
- Shandisa camera's viewfinder, panzvimbo yeLCD, kuisa pfuti.
- Zvichengetedze iwe sezvaunopfura nekuzendamira pamadziro kana musuo gonhi.
- Shingairira zvipfeko zvenyu kune rumwe rutivi rwemuviri wenyu uye mubatisise kamera nemaoko maviri.
- Shandura pa fast shutter speed nguva yose, iyo isiri nguva dzose inoshandiswa.
Usakanganiswa
Pakupedzisira, iva nechokwadi chokuti unonzwisisa chaizvo zvaunenge uchizvitenga kana zvasvika pakugadzikana kwechifananidzo mu digital kamera yako. Vamwe vanogadzirisa, kunyanya avo vane mitengo yakadzika, vanoshandisa mazwi ekutsausa, akadai se-anti-blur mamiriro kana anti-shake technology, kuedza kuvanza kuti iyo digital kamera haina kupa IS. Makamera akadaro kazhinji anowedzera kuvhara kwekuvhara kwemafirimu, izvo dzimwe nguva zvinokonzera dzimwe dambudziko rekusangana, zvichikuvadza kunaka kwechifananidzo.
Sezvinyorwa zvinowedzera, mamwe makambani ekugadzira kamera ane mazita emhando chaiyo ekugadzikana kwechigadzirwa chemifananidzo, kuwedzera kuomesa zvinhu kune shopper (sokuti tinoda kuwedzera kuvhiringidzika). Semuenzaniso, Nikon dzimwe nguva anoshandisa "Kubvisa Kuderedza," uye Sony dzimwe nguva rinoshandisa "Super Steady Shot" kutarisa optical IS. Canon yakagadzira rudzi rwechimiro chekusimudzira iyo inowanzoreva seAngwara IS.
Usati watenga imwe mienzaniso, iva nechokwadi chokuti zita rayo rezita rinoreva optical IS uye kwete imwe yerimwe digital IS. Iwe unokwanisa kukwanisa kuwana ruzivo urwu kune webhupu yezvigadzirwa kana kubva kune mutengesi anotengesa pachitoro chako chekhamera.
Mazuva ano makamera emazuva ano anowanzobatanidza optical IS kana kuti anosanganisira imwe nzira yeIndaneti, saka kuwana kamera yakarurama kuti usangane nechimiro chako chekugadzikana kwechimiro hachisi chinhu chinokosha chekufunganya sekunge kwave kwakave makore akawanda akapfuura. Kunyange zvakadaro, kuva nechimiro chakanaka chekugadzirisa hurongwa kunokosha zvakanyanya pakubudirira kwekamera yako yedijititi iyo inofanirwa kuongorora kaviri kamera yako ine mhando yakanakisisa yeI. Usakanganwa kutarisa ikamera yechirongwa chekutsvaga yerudzi rwechimiro chekugadzikana chiripo!
