Chirimwa chinhu - izwi iri kuwedzera duramazwi Photographic mashoko ari kubuda uye kushandiswa kwakapararira chizvarwa chitsva Camera. With kukura ano itsva ruzivo pamisika vakatanga kuonekwa zvakawanda digitaalinen SLR makamera ane mari nyore nonprofessionals. Vatengi kwakadaro, kuwedzera mutengo, kusiyanisa kana mumwe chikamu, iro yasarudzwa kamera - inhamba megapixels. With megapixels havana zvimwe afunga, uye kupa vaguely, chii chaizvoizvo vachiri kunzwisisa kuti zvimwe ari mudziyo nani. Zvisinei, sezvo zvikazooneka, mumwe inokosha unhu siyanisa unhu pakati digital kamera, zvibereko chinhu. Usati kutenga kamera, amire vachiri kufunga kuti chii.

Shoma amateurs kanenge kamwe nei, kana izvo uye izvo ane dzeraundi makavharidzira chimiro, pamatanda panguva iyoyowo vanotora rectangular? Hapana kuoma iri mhinduro yomubvunzo uyu kwete. Projecting kuti unotorwa mifananidzo mufananidzo kune vezvenhau vari kamera, zviri izvo optics anongoti paanoparadza chikamu "mamwe" nomufananidzo, zvichiriita rectangular chimiro. Zviri nyore chaizvo kuti pagadzirwe firimu rine munhevedzano rectangular mapuranga, uye kugadzira mifananidzo, uye kupa nezvimwe tsindirana, uye ichiita mabasa akawanda.

Nokuda kushandisa film-refu mifananidzo kukura pakati pamatanda pamusoro firimu kuramba kushandiswa sokunoratidza saizi. Hapana kunyange hakuitiki kuchinja nayo kunyange ikozvino, kana kupfura pamusoro firimu iri kusvika chinhu chekare. Mazuva ano, pamwechete accession pamusoro digital mufananidzo kupfura pamusoro chaiyo chizvaro, izvo zvinogona nehasha kuenzaniswa firimu.

Matrix, rinova ukuru runoenzanirana firimu puranga, inonzi yakazara pepuranga. Zvisinei, vakawanda digitaalinen SLR makamera ane chizvaro ane saizi duku zvikuru. Sezvingatarisirwa pamusoro matrices zvakadaro mwoyo chete nechepakati nzvimbo nomufananidzo kuti vasvike renguva pamwero chizvaro. Nemaziso, zvinoita sokuti mufananidzo by izvo puranga ane yakareba zvatichiri yakareba.

Nokudaro akamuka izwi kuti inorondedzera "kuwedzera" musimboti wokuzadzika urefu, iyo here kuitika, nekuti pano, sezvo vari muenzaniso hwedu kumativi lenses, anongoti akagura chokunze chikamu pamatanda. In Chirungu shoko "chirimwa" (chirimwa) rinoshandurwa kuti "kugurwa". Saka zita rokuti - chirimwa chinhu, izvo zvinoreva kuti zviri artificially zvakawedzera zvatichiri kureba. Rinorondedzera zvakarurama panguva imwe chete, chokwadi pane chirongwa kupfura, sezvo ari panyama mupfungwa, kamera izvo zvatichiri kureba haina kushanduka, asi chete kushandura pakona maonero.

Saka, muviri Sizes 35 timillimetrovoy firimu 24x36 mm yave uye anoramba ari reference, iyo zvino kwakabatana uye zvirimwa chikonzero. Chakadaro furemu zviri akaenzana 1. Pakutanga yaitonga, nouchenjeri Nikon-digital mifananidzo vakasarudza kuti zvinokwanisika kuti pave digitaalinen SLR makamera vachikwanisa kushandisa pamwechete optics wekare, ivo vakaitwa kwemakumi emakore uye zvinowanzodya kupfuura kamera pachayo.
