Pakuti ambiri ojambula - ndi ntchito, koma kwa ena - chizolowezi, koma Mulimonsemo chithunzi ndi nthawizonse mmodzi wa mitundu luso. Ndipo ngati inu kusankha kwambiri kapena zochepa kwambiri kuthana ndi digito kujambula, ndiye choyamba muyenera chitani kusankha abwino yakamerayi. Chifukwa makamera akatswiri okwera mtengo, ndipo amene adzakhala chinkhoswe mu ankachita masewera kutenga chithunzi, chabe safuna, chifukwa cha ichi ambiri abwino theka-akatswiri kamera. Komabe, si yeniyeni, koma yosokoneza ndi mfundo zambiri. Tsopano inu mukudziwa chimene izo zikutanthauza ndi mmene kusankha theka-kamera.

Kamera theka-akatswiri ndi osiyana ndi "Sopo"?

Gulu la makamera lakonzedwa kuti anthu amene ali ndi mpata yovomerezeka "Sopo", koma amene Sapita ntchito kamera zamitundu yosiyanasiyana, ndiko ntchito situdiyo.

Choyamba, kamera izi kusiyana ndi luso pamanja kusintha ISO tilinazo, ndiye mlingo wa tilinazo masanjidwewo, ndi mphamvu Iris kulamulira ndi kukhudzana, Buku kwambiri. Komanso, makamera amenewa pamanja adakhazikika woyera. Monga makamera onse theka-akatswiri mosiyana ochiritsira "Sopo", n'zotheka kusintha disolo. Chimodzi mwa zinthu zoopsa tipanga Kamera kusankha theka, ndi zosiyanasiyana magalasi a mtundu uliwonse, umene umabala makamera. Pa Optics mmene lonse paki ku kampani makamaka ndi momwe Optics amenewa akupezeka kwa wogula, ndipo amadalira kusankha kamera.

ndi ISO, shutter liwiro ndi kabowo chiyani?

Ngati mukufuna kutsata kujambula ndi akadali anakumana ndi mfundo imeneyi, ndiye inu amafunika kudziwa chomwe icho chiri. ISO - ndi mlingo wa tilinazo wa kamera masanjidwewo. The apamwamba phindu, tilinazo apamwamba, koma pa mfundo apamwamba a phokoso zayamba (Stock chithunzi kuchuluka kwa pixels achikuda). Choncho ndi bwino ngati n'kotheka kupewa zoikamo ISO kwambiri mu kuwala otsika, akulipira kuwala otsika ndi kutalikitsa kukhudzana ndi. Musanayambe kusankha kamera ndi theka-chomaliza kusankha chimene inu kugula chitsanzo ichi, kutali zedi kuona zithunzi anatengedwa ndi chitsanzo ichi kamera ndi zoikamo mkulu ISO, pamene akuona mlingo wa phokoso pa cipangizo.

Ndinakumana - kuchuluka kwa nthawi imene vavu pakati pa disolo ndi masanjidwewo kamera lidzatsegulidwa. Izi imeneyi nthawi mwina kuchokera tuzigawo twa angapo a wachiwiri kwa masekondi angapo. Ochokera kuchuluka kwa kuwala zimatengera, umene ndi nthawi kuti masanjidwewo lapansi. Koma kukhudzana yaitali kwambiri kungachititse zithunzi khungu, pofuna kupewa zimenezi, wolakalakika ntchito miyendo itatu.

Kabowo - chipangizo mu mandala ongokhala pamakhala. Ndi wakutsegula ndi kubisa kumbuyo. Pamene kabowo mu masanjidwewo afika dzuwa kwambiri, kotero inu mukhoza kupulumutsa mofulumira shutter liwiro. Komanso mmene poyera zakulera zimatengera kuya kwa munda (DOF). Ngati zakulera ndi lotseguka, kuya kwa munda zidzakhala zochepa ngati anaphimba - kwambiri.

Features DSLR

Otchedwa "reflex" - kamera, galasi chipangizo chimene ntchito, kuti dzina lake likunenera. Malowa ali pamtunda kutsogolo kwa masanjidwewo pa makona a madigiri makumi asanu ndipo amakhala ku kufika pa chithunzi kuchokera mandala mwachindunji mu viewfinder, imene inu yang'anani. chithunzi ichi mozondoka, choncho palinso pentaprism, amene imadzitembenuzanso fano zimaonekera pa galasi kapangidwe SLR.

Palinso "LayvVyu" mode SLR makamera, amene amalola inu kusonyeza chithunzi pa zenera kamera ndi yaing'ono. Ngati sakufuna ntchito viewfinder kuwala, chifukwa mumakonda kutenga zithunzi, kuika mtima pa zenera, galasi mu kamera sadzakhala inu kugwira ntchito iliyonse.

Kupanga makamera amenewa zikugwira Makampani ambiri, wotchuka kwambiri a iwo - ndi "Canon" ndi "Nikon". Yankho la funso za mtundu wa theka-mandala reflex kamera kusankha kudzadalira nkhalidwe yau chuma ndi zokonda ndi zokonda. Pamene kusankha kamera motsogozedwa ndi mmene omasuka ali m'manja mwake, monga momwe pali yabwino wazakudya ndi batani mawonekedwe, ndi zina zotero. D. Ndipo, ndithudi, mtundu wa zithunzi. Mukhoza kuchita angapo akatemera mayeso kwa makamera osiyana mu sitolo, kenako tayang'anani pa zenera chachikulu, chimene chiri bwino. Pa kuwonetsera Integrated wa kamera kuonanso ubwino wa zithunzi ndi kovuta.

makamera System

System (kapena, ngati iwo amatchedwa, mirrorless) makamera - kamera, limene palibe galasi ndi pentaprism moyenera, palibe viewfinder kuwala. Ku chinthu chimodzi "mphukira makamera" amadziŵika ndi kukhalapo kwa kamera zoikamo onse Buku, luso kusintha disolo, ikuluikulu kukula thupi la masanjidwewo lapansi. Ilo lachokera izi zidalira pa kukula ndi khalidwe la zithunzi. Ikuluikulu masanjidwewo, m'pamenenso zithunzi apamwamba inu mukhoza kulowa mu kuwala otsika, chindichepere adzakhala pa phokoso lomwelo. Choncho, ngakhale ngati inu kusankha "Sopo" mu malo oyamba ayenera kulabadira kuti chiwerengero cha megapixels, ndi kukula thupi la masanjidwewo kapena pa chinthu mbewu. Mbewu chinthu - mtengo lomwe limasonyeza bwanji kukula kwa masanjidwewo ndi zosakwana zonse chimango kukula (35h24 mm). Mwachitsanzo, mbewu chinthu cha 2 zikutanthauza kuti masanjidwewo ntchito kamera, nthawi 2 kakang'ono kuposa onse chimango kukula. Masiku ano, Makamera zonse chimango masanjidwewo n'zochepa ndipo akatswiri, kuwonjezera, iwo ali, ndithudi, ali wa mtengo wapatali.

dongosolo akadali makamera zambiri limagwiritsa ntchito bokosi 17,3h13 mamilimita kukula, i.e. 3x4 mainchesi. Mbewu chinthu liri awiri. Pasanathe ambiri ntchito masanjidwewo mbewu chinthu cha 1.5, i.e. yofanana ndi tinyumba tina mu kamera ndi SLR. Makamera mawerengetsedwe otere ambiri ndi "Sony" - Ndi mmodzi wa opanga wotchuka makamera mirrorless.

Komanso ndi odziwika bwino kwambiri opanga mirrorless makamera ndi "Olympus" ndi "Panasonic".

nyumba

Ndiye kodi kusankha kamera theka-akatswiri, ndipo mukufuna wabwino, onetsetsani kulabadira ubwino wa chuma pulasitiki za thupi. Komanso nyumba kungakhale zitsulo - ziri bwino. Onetsetsani kuti ndi kamera mu sitolo muyenera akanikizire batani zonse kuti titsimikize kuti amagwira ntchito bwino ndipo si kumira.

Ndiye kodi kusankha theka-akatswiri kamera - ntchito udindo, mungapeze ndemanga wosuta za makamaka kamera chitsanzo kuti limakusangalatsani (pamaso mumachita kugula).

Chongani masanjidwewo kamera musanachigule

Tsopano inu amadziwa kale kusankha theka-kamera, ndipo inu mukhoza kupita ku sitolo. Pamene inu kale mwasankha chitsanzo kuti mukufuna kuti aone khalidwe la msonkhano wake, ndi kugwira mayeso wina waung'ono - Yang'anani pamaso pa bokosi kamera wosweka ndi pixels otentha. Kuswa - anthu pixels amene inoperative ndipo samva kuwala, mwayera mfundo. Hot - komanso zosalongosoka pixels, amene nthawi zonse ndi mtundu wina.

Kuyesa kufunika kuthimitsa kung'anima, kutseka kamera mandala ndi kupanga angapo akatemera pa exposures osiyana. Pa njirayi, malo otsikitsitsa ISO ayenera kukhazikitsidwa, pazipita chithunzi kusamvana ndi phokoso-kusintha ntchito ndi ikanazimitsidwa. Tsopano tiyenera kuona zithunzi izi pa nsalu yotchinga chachikulu.

Ngati pali zithunzi mawu a mitundu yosiyanasiyana - ndi masanjidwewo ukwati, monga yotentha kwambiri ndipo akufa pixels. Iwo adzakhala pano pa zonse, popanda yekha, zithunzi anagwidwa ndi kamera, makamaka zosasangalatsa ngati ali pakati. Ngati chithunzi ndi wakuda kwathunthu, mukhoza bwinobwino kutenga chitsanzo ichi.
