Ko "kutsanya" kunorevei kana tichitaura nezvemaresi?
Mabhizimisi akawanda anoshandisa mazita avo emitauro, mazwi asinganzwisisiki kune imwe nzvimbo, mabzzwords, zvinyorwa zvezvishandiso, maitiro kana teknolojia inongoreva chimwe chinhu kwavari. Kubudiswa kweVhidhiyo hakuna kusiyana.
Uyu munyori akapinda muvhidhiyo yekugadzirwa mumavambo ekutanga kwema2000, pedyo nenguva iyo digital yakatanga kugadzirisa kuti tape isingashandisi, kana kuti yakanyanya kuderera. Kurayirirwa kutora vhidhiyo pahofisi yakagadzira magazini, pakange pasina vezera vanoshevedza, pasina vamwe vapfuri kana vaparidzi kukumbira rubatsiro. Izvozvo zvakasiya zvimwe zvingasarudzwa: mabhuku uye internet.
Zvakanaka, kudzidza kupfura uye kuchinja kwaiva kwakarurama. Ikoko kwakanga kune zvishandiso, paive nemichina uye pane nzira dzakarurama uye dzisiri dzekuita mabasa. Pandakanga ndisinganzwisisi kuti shoko rinorevei kana rima rakamira pakasvika makamera nekupfura, ndinogona kuGoogle iyo, kana ini ndingangodzidza kuti bhatani kana chigadziro zvakadini uye ndozviisiya ipapo.
Zvinosuruvarisa kuti zvandaireva kuti ini, sezvizhinji zvekudzidziswa kwevhidhiyo vhidhiyo uye zvinowedzera, vari kudzidza vhidhiyo remagetsi pamhepo.
Rimwe remashoko ayo anowanzoshandiswa asi harisi kunyanya kujeka muchirevo nderokutaura kune "lens". Ko "kutsanya" kunorevei kana tichitaura nezvemaresi?
Zvakanaka, pane zvinhu zvishomanana pane kamera inogona kukurumidza, asi izwi iri rinotaridzirwa kumhepo yakakura ye lens. Iyo yakawanda iyo yakakura yekhamera, iyo yakajeka iyo inotumirwa kusvika kumusana wemufananidzo wekamera.
Saka, nzira iri nyore yokutarira nokukurumidza uye inononoka lenses ndeyekufungidzira kuti iyo lens inokurumidza inowedzera mune imwe chiedza uye inononoka lens inotora zvishoma.
Saka zvinorevei chaizvo kuti utaure zvakanyanya? Zvakanaka, kubhururuka kwema-lens ndiko kukwirira kwedenderedzwa rakasununguka, kana diaphragm, mukati me lens. Izvi zvakanyanya nzvimbo iyi ndeyekuti, chiedza chinowedzera chinowedzera kuburikidza ne lens. Inonzwisisa, huh?
Iyi lens yepamusoro yakaratidzwa kwatiri tichishandisa f-nhamba , yakadai f / 1.8 kana f / 4.0. Iyi f-nhamba inoreva chirevo chemasvomhu, uye patinenge tisingapindi mairi, inotibvumira kushandisa lenzi dzemakiromita akasiyana-siyana uye tinoziva kuti tichava nemafungiro akafanana ekutsvaga.
Saka heinoi iyo nhamba yef f inoshanda sei: Dzasi pasi f-nhamba, iyo yakawanda. Sezvatakadzidza mberi, iyo yakawedzera kuputika, kunyanya chiedza chinosvika pane sensor. Icho chiedza chinowedzera kusvika kune sensor, nekukurumidza lens. Tarisa pasi f-nhamba dzakaderera se f / 1.2, f / 1.4 kana f / 1.8.
Mukutaura, iyo yakakwirira f-nhamba, zvishoma zvishoma. Kudukuka kuduku kunoreva kuderera kuduku kupfuura nepakati pe lens kusvika kune sensor. Izvi zvinononoka kutora lenzi dzichava nemafuta makuru-f, akadai f / 16 kana f / 22.
Aya mashoko ose akanaka uye akanaka, asi nei mamwe mavhidhiyo anofarira kuwedzera pamusoro pezvibatsiro zvekurumidza lenses? Zvakanaka, pane zvikonzero zvishoma zvakanaka.
Yokutanga ishoma chiedza senzwi. Chimwe chiedza chinobvumira sensor kuti iite basa kunze kwekuda kuziva nzvimbo dzakaoma. Kuwedzera kwechiedza kunoreva kusafanira kuvhara ISO kuchengetedza chifananidzo chikajeka, uye sezvawakangodaro wakawana ikozvino, kukwirira kweIO zvirongwa zvinoguma nekutinhira kwemufananidzo.
Chimwe chikomborero ndechokuti ruvara, ruzivo rwemamiriro ezvinhu isu tinoona muzvidzidzo zvep. Izvozvo kubva pane zvakakanganisika ndezvinodiwa, uye zvinoreruka zvikuru kubudirira nekutsvaira kwemajeri.
Kubva kumativi ose, mashizha ekukurumidza anobvumira vapfuri kuti vashandise nekuvhara nokukurumidza, sezvo chiedza chinosvika kune sensor chikuru. Izvi zvinogona kubatsira kubvisa pafurati yekufamba.
Sidenote: paunenge uchipfura paunenge uchitarisa, taura f / 2.8 pane lenzi iyo inokurudzira panzvimbo iyo, vazhinji vanopfura vachataura kuti "kuputika kwakazaruka". Kana iwe wakambogadzwa uye mumwe mutungamiriri anorayira kupurudza "yakazaruka" kuti ushandise mamiriro ekugadzirisa, ingoisa kamera yako kusvika pakakwirira, uye iwe wose uchagadzirirwa.
