Chida Chinsinsi cha Ojambula: Mabatani Obwerera Kumbuyo Kwa Zithunzi Zowonekera

Ngati mwawerenga mabulogu ojambula, kucheza ndi ojambula zithunzi, kapena kucheza ndi ojambula ena, mwina mudamvapo mawuwo "Kuyang'ana kumbuyo batani" otchulidwa. Ndizotheka kuti simukudziwa chomwe chikuchitika, kapena mwina mwamva kuti mutha kujambula zithunzi zolimba ndi batani lakumbuyo koma simukudziwa. Mutha kufunsanso ngati ndichinthu chomwe muyenera kuchita kapena ayi. Cholemba ichi chikuthandizani.

Choyamba, batani lakumbuyo ndikutani?

Mwachidule, batani loyang'ana kumbuyo ndikugwiritsa ntchito batani kumbuyo kwa kamera yanu kuti mukwaniritse zowunika m'malo mogwiritsa ntchito batani loyang'ana. Zimadalira mtundu wa kamera yanu ndi mtundu wa batani lomwe mudzagwiritse ntchito ntchitoyi. Ndikuwombera Canon. Chithunzi pansipa ndi limodzi mwa matupi anga a Canon; batani la AF-ON kumanja kwake limagwiritsidwa ntchito ngati batani lakumbuyo (BBF) pathupi langa lonse. Ma Canon ena amagwiritsa ntchito batani losiyana, kutengera mtunduwo. Mitundu yosiyanasiyana ilinso ndi mitundu ina yosiyana siyana, chifukwa chake onani buku lanu la kamera kuti mudziwe batani logwiritsira ntchito batani lakumbuyo.

Kodi ndizosiyana bwanji ndi batani lakumbuyo (BBF) ndipo zingandipatse bwanji zithunzi zowongoka?

Mwaukadaulo, kugwiritsa ntchito batani lakumbuyo kuyang'ana kumachita chimodzimodzi ndi batani la shutter: limayang'ana. Sigwiritsa ntchito njira ina iliyonse yomwe imakupatsani zithunzi zakuthwa. Pamwamba, mabatani onsewa amachita chimodzimodzi. Pali zabwino zingapo pakubwezeretsa batani kumbuyo - ndipo zimatha kukuthandizani kuti mukhale akuthwa. Ubwino waukulu wa BBF ndikuti imasiyanitsa batani la shutter kuti lingoyang'ana. Mukayang'ana pa batani la shutter, nonse mumayang'ana ndikumasula shutter ndi batani lomwelo. Ndi BBF, ntchito ziwirizi zimachitika ndimabatani osiyanasiyana.

Mutha kugwiritsa ntchito BBF m'njira zosiyanasiyana. Ngati mukugwiritsa ntchito kuwombera kamodzi, mutha kudina batani lakumbuyo kamodzi kuti mutseke ndikuwunika kumatsalira pamalo amenewo mpaka mutakanikizanso batani lakumbuyo kuti muyambenso. Izi ndizopindulitsa ngati mukufuna kujambula zithunzi zingapo (monga zithunzi kapena malo owoneka) okhala ndi mawonekedwe omwewo komanso malo owonekera. Simuyenera kuda nkhawa kuti mandala adzawonikanso nthawi iliyonse mukakhudza batani; cholinga chanu chatsekedwa mpaka mutasankha kusintha ndikusindikiza batani lobwerera.

Ngati mukugwiritsa ntchito njira ya servo / AF-C, kuyang'ana kumbuyo kwa batani kumatha kubwera mosavuta. Mukamagwiritsa ntchito njirayi, magalimoto anu oyang'ana magalasi akuyenda mosalekeza, kuyesera kuyang'ana kwambiri pamutu womwe mukutsata. Mwinanso mutha kuwombera kangapo pomwe mukuchita izi. Nenani kuti mukugwiritsa ntchito batani ndikuyang'ana mutu, koma china chake chimabwera pakati pa mandala anu ndi mutu wanu. Pogwiritsa ntchito batani, makina anu amayesa kuyang'ana pazotchinga bola chala chanu chikhale pa batani, ndikujambula zithunzi. Komabe, mukamayang'ana ndi batani lakumbuyo, ili si vuto. Kumbukirani momwe ndidanenera kuti BBF imalekanitsa batani kuti lingoyang'ana? Apa ndi pomwe zimabwera bwino kwambiri. Ndi BBF, ngati muwona cholepheretsa chikubwera pakati pa mandala anu ndi mutu wanu, mutha kungochotsa chala chanu chakumbuyo ndipo batani loyang'ana magalasi lidzaleka kuthamanga ndipo silingayang'ane zolepheretsa. Muthabe kupitiliza kuwombera ngati mungafune. Cholepheretsacho chikangoyenda, mutha kuyika chala chanu chakumbuyo kumbuyo ndikubwezeretsanso kutsatira zomwe mukuyang'ana.

Kodi kuyang'ana kumbuyo kwa batani ndikofunikira?

Ayi. Zimangokhala nkhani yokonda. Pali ojambula omwe amapindula nawo, monga ojambula masewera ndi ojambula zithunzi zaukwati, koma ngakhale safunikira kuti azigwiritsa ntchito. Ndimagwiritsa ntchito chifukwa ndimayesera, ndimakonda, ndipo ndinazolowera kugwiritsa ntchito batani langa lakumbuyo kuti ndizingoyang'ana. Tsopano ndikumva zachilengedwe kwa ine. Yesani kuti muwone ngati mumakonda komanso ngati ikugwirizana ndi momwe mumawombera. Ngati simukuzikonda, mutha kubwereranso ku batani loyang'ana.

Kodi ndimakhazikitsa bwanji batani langa pakamera yanga?

Njira zenizeni zokhazikitsira zimasiyana kutengera mtundu wa kamera yanu ndi mtundu wake, chifukwa chake ndibwino kufunsa buku lanu kuti mudziwe momwe mungayambitsire batani lanu pakamera yanu. Malangizo angapo (ndaphunzira izi kuchokera pazondichitikira!): Makamera ena ali ndi mwayi wokhala ndi batani lakumbuyo ndi batani loyang'ana lomwe limagwira nthawi imodzi. Onetsetsani kuti mukusankha mawonekedwe omwe adadzipereka makamaka kuti musungire batani kumbuyo kokha. Komanso, ngati muli ndi kamera yakutali yopanda zingwe yomwe imaloleza autofocus, mwayi ndi kamera yanu yomwe singayikenso pogwiritsa ntchito kuchotsa ngati muli ndi BBF pakamera. Ngati mukufuna kuyika autofocus ndikugwiritsa ntchito chosungira, muyenera kusintha kamera kuti iziyang'ana batani kwakanthawi.

Kuyang'ana kumbuyo sikofunikira koma ndi njira yomwe ojambula ambiri amapeza yofunikira. Tsopano popeza mukudziwa kuti ndi chiyani komanso maubwino ake, yesani kuti muwone ngati ndi anu!
