Kugwiritsira ntchito kwake kungapulumutse kwambiri nthawi ya wojambula zithunzi - ngati ntchitoyo silingagwirizane ndi chipangizochi, ndiye ntchito yomweyi imagwiritsidwa ntchito pa PC pogwiritsa ntchito olemba ojambula.

Chinthu china chodziwika cha Sony NEX 7 ndi kuphatikiza mafelemu apansi. Sony mwachizolowezi amaonedwa kuti ndi imodzi mwa zinthu zoyendetsera polojekitiyi - choncho zomwe zilipo ndi njira yabwino kwambiri.

Zida zamagwiritsidwe ntchito kachipangizo

Tiyeni tiphunzire tsopano zomwe zimakhala zovuta zogwiritsira ntchito kamera. Choyamba, tikuzindikira kuti mukhoza kuyamba kuwombera pambuyo pa 0.64 mutatsegula chipangizochi. Chizindikiro ichi mwina sichoncho chowonekera kwambiri - njira zothetsera mpikisano zambiri zimagwira bwino bwino, koma ndizovomerezeka pa zochitika zambiri zogwiritsa ntchito kamerazo.

Chimodzi mwa njira zotchuka kwambiri pa chipangizocho ndi kuwombera pang'onopang'ono. Monga lamulo, imayendetsedwa mu ma modesiti atatu - polemba ma JPG mafayilo osakanikirana, polemba deta mu mawonekedwe a RAW, komanso palimodzi momwemo - komanso ndi chiwerengero chochepetsedwa kwambiri. Malingana ndi zida zomwe zimadzinenedwa, kamera ya Sony NEX 7 ikhoza kuthamanga mofulumira pa mafelemu pafupifupi 10 pamphindi. Kodi izi zili choncho?

Monga momwe zikusonyezedwera ndi mayesero ochitidwa ndi akatswiri, chipangizo chonsecho chimapereka liwiro lodzinenera la kuwombera. Zoona, malingana ndi mafayilo omwe amagwiritsidwa ntchito, chiwerengero cha mafelemu a mndandanda umodzi wa zithunzi zotsalira zidzasiyana. Ngati zithunzi zalembedwa mu JPEG, ndiye kuti padzakhala mafelemu 13 pamzerewu, ngati kugwiritsa ntchito RAW standard - 12, ngati mafomu onsewa agwiritsidwa ntchito panthawi imodzi, 11.

Chinthu china chofunika kwambiri kuchokera kumbali yogwiritsa ntchito chipangizochi ndilo liwiro loyang'ana. Chipangizo chomwe chili mu funso chikuwonetsa zotsatira zabwino pakuyesa izo.
