Ndeapi mabasa makuru ari pakamera yeDSLR anokanganisa kuratidzwa kwakarurama kwomufananidzo?
Context:Mukufotora, kukosha kwekuratidzira (EV) inhamba inomiririra mubatanidzwa wekuputika kwekamera uye f-nhamba, zvekuti zvese zvinongedzo zvinoburitsa kuratidzwa kwakafanana zvine EV yakafanana (kune chero yakatarwa chiedza chechiitiko). Kukosha kwekuratidzira kunoshandiswawo kuratidza nguva iri pachiyero chekuratidzira kwemifananidzo, nemusiyano we1 EV unoenderana neyakajairwa simba-re-2 danho rekuratidzira, rinowanzo kunzi kumira.  Pfungwa yeEV yakagadzirwa nemugadziri wechiGerman wechiGerman Friedrich Deckel muma1950 (Gebele 1958; Ray 2000, 318). Chinangwa chayo chaiva chokurerutsa kusarudza pakati pezvigadziro zvakaenzana zvekuvhenekera kamera nekutsiva kusanganiswa kwe shutter speed uye f-nhamba (semuenzaniso, 1/125 s pa f/16) nenhamba imwechete (semuenzaniso, 15). Pamamwe magirazi ane mabutiro ane mashizha, muitiro wacho wakaitwa kuti uve nyore nokuita kuti mabutiro nemabhuroko zvinyatsobatana zvokuti, apo imwe yaichinjwa, imwe yacho yaigadziriswa zvoga kuti irambe iine chiedza chakafanana. Izvi zvainyanya kubatsira kune vaya vainge vachangotanga kudzidza asi vaisaziva kuti shutter speed neaperture zvinobatana sei. Asi zvaibatsirawo vatori vemifananidzo vaiva neruzivo avo vaigona kusarudza shutter speed kuti vamise kufamba kana kuti f-number nokuda kwoudzamu hwomunda, nokuti zvaibvumira kugadziridza nokukurumidza - pasina kudikanwa kwokuverenga mupfungwa - uye zvaideredza mukana wokukanganisa pakugadzirisa.
Kana kamera yeDSLR isina kuiswa mu'Automatic' mode, pane zvinhu zvitatu zvinokosha zvinofanira kufungwa nezvazvo pakusarudza kuvheneka kwakarurama kwomufananidzo wako. 1) Aperture - kuti aperture iri pa lens yakafara zvakadini inosarudza kuti chiedza chakadini chinogona kupfuura nepaaperture yacho. Chivharo chiduku (semuenzaniso f/16) chinobvumira chiedza chiduku kusvika kune sensor kusiyana nechivharo chakakura (semuenzaniso f/2.4). 2) Shutter Speed - nguva yakareba sei iyo shutter inobvumirwa kuramba yakazaruka pashure pokunge wadzvanya kusunungura pakamera. Nguva pfupi yekuratidzira (semuenzaniso 1/1000 sec) ichabvumira mwenje mushoma kurova sensor yekamera nepo kuratidzwa kwenguva refu (semuenzaniso 1/4 sec) kuchibvumira mwenje wakawanda kurova sensor 3) ISO setting - iyi setting inoshandiswa kudzora kuti sensor inonzwa sei kuti chiedza chichiirova. A pasi ISO marongero (semuenzaniso ISO 200) ari zvikuru asinganzwisisiki pane yakakwirira ISO marongero (semuenzaniso ISO 1600) izvo zvinoreva zvishoma chiedza kunodiwa kuti abate mufananidzo pamusoro Switch. Mabasa ose matatu aya anoshanda pamwe chete kuti ave nechokwadi chokuti kukosha kwakarurama kwokuvhenekera kunogadzirwa kwakavakirwa pamufananidzo nomugumisiro wauri kuedza kugadzira.
