Kamera ya Sony A7000 yopanda magalasi yopereka ma 15.5-stop dynamic range

Chidziwitso chatsopano chokhudza kamera ya Sony A7000 yotsogola yopanda magalasi yowululidwa chavumbulutsidwa ndipo chikuti chipangizocho chidzagwiritsa ntchito chojambulira cha zithunzi ndi 15.5-stop dynamic range ndi native HDR.

Pakudutsa mphindi iliyonse zimawonekeratu kuti kamera ikubwera ya A6000 idzatchedwa Sony A7000. Idzalowa m'malo mwa NEX-7 ndipo idzakhala kamera yopanda magalasi yotsogola yotchedwa E-mount yokhala ndi sensa ya APS-C.

Chida chodziwika bwino chimamasulira mawonekedwe apamwamba ndipo zikuwoneka ngati A7000 iperekadi moyenera. Chokopa chachikulu cha chiwonetserochi chidzakhala sensa yake yomwe ipereke mphamvu zosayerekezeka komanso kutengera kwa HDR, magwero awulula.

Sony NEX-7 idzasinthidwa ndi kamera yotchedwa A7000 yomwe idzagwiritse ntchito sensa yokhala ndi 15.5-stop dynamic range.

Sony A7000 ili ndi mphekesera zokhala ndi ma 15.5-stop dynamic range

Sony ndi kampani yotsogola muukadaulo wa sensor womwe umayika pamwamba pamisika yama sensa. Kampani yochokera ku Japan yalengeza posachedwapa za A7R II, kamera yoyambirira yathunthu yokhala ndi sensa yowunikira kumbuyo.

Komanso, a RX100 IV ndi RX10 II zaululidwa pambali pa A7R II yodzitamandira sensa yoyamba ya 1-inchi yokhazikitsidwa padziko lonse lapansi ya CMOS. Komabe, wopangayo sadzaima pamenepo, popeza mphekesera ikunena kuti Sony A7000 idzakhala kamera yoyamba ya APS-C padziko lonse lapansi yokhala ndi 15.5-stop dynamic range and on-sensor HDR.

Tsiku loti alengezedwe m'malo mwa NEX-7 silikudziwika, koma oyimba mkati akuti atha kupezeka nthawi ina kugwa uku ndi zolemba zingapo zosangalatsa.

Kodi ma 15.5-stop dynamic range ndi sensor ya HDR amatanthauza chiyani?

Ojambula ojambula amasangalala kukhala ndi malo okhala ndi 15.5-stop. DR yowonjezeredwa imathandiza ngati zochitika zimaphatikizapo madera olimba kwambiri komanso otsika kwambiri. Zinthu ngati izi nthawi zambiri zimakumana masana kukamawala, pomwe madera ena amada.

Kuti mupereke zithunzi zabwino pamikhalidwe ngati imeneyi, njira yotchedwa high dynamic range (HDR) kujambula yakonzedwa. Kwenikweni, kamera imagwira zithunzi zitatu m'malo osiyanasiyana kuti zitsimikizire kuti madera onse owonekera awululidwa moyenera pachithunzicho.

Zikuwoneka kuti sitepe yotsatira ndiyomwe imakhala pa-sensor ya HDR yoperekedwa ndi Sony A7000's 15.5-stop dynamic range. Ndi ukadaulo wamba wa HDR, kamera imagwira zithunzi m'malo osiyanasiyana, koma ndi njira yatsopanoyi idzajambula chithunzicho ndikuwonetsera kwake kumasiyanasiyana ndi mizere iwiri ya pixel. Izi zikutanthauza kuti ogwiritsa ntchito sadzayenera kuwombera zithunzi zitatu zosiyana kuti agwire kuwombera kwa HDR.

Palibe zambiri zomwe zikupezeka pamomwe ukadaulo wa HDR wamtunduwu ungagwire ntchito, koma zikumveka zosangalatsa. Khalani pafupi ndi Camyx kuti muwone momwe nkhaniyi ikuwonekera!
