Dzokera kuBasics Photography: In In Depth Tarisa kuIO

Mumwedzi inotevera John J. Pacetti, CPP, AFP, vachange vachinyora nhevedzano yezvidzidzo zvekutora mifananidzo.  Kuti uzviwane zvese chingotsvaga "Dzokera kuBasics”Pane yedu blog. Ichi ndicho chinyorwa chechitatu munhevedzano ino. John anogara achishanyira iyo MCP Facebook Nharaunda Boka. Ita shuwa yekujoinha - ndeye mahara uye ine ruzivo rwakawanda kwazvo.

Muchinyorwa chedu chekupedzisira ndakakupa tarisiro penzvimbo yekuratidzira. Ino nguva tichaenda zvakadzika neIO.

ISO ndiko kunzwisisika kwenzwi. Iyo sensor inounganidza mwenje. Chiedza pane sensor ndicho chinogadzira mufananidzo wako. Iyo yepazasi iyo ISO nhamba ndiko kuwedzera mwenje kunodiwa kugadzira chifananidzo, yakajeka mifananidzo. Iyo yakakwira iyo ISO nhamba mwenje mushoma unodikanwa kuti ugadzire mufananidzo, zvimiro zvakasviba.

Kuziva izvo ISO zvinoita kunge kuri, maonero angu, akanyanya kupotsa anonzwisiswa ezvikamu zvitatu zve iyo katatu yakatarisa. Kana iwe uchinetseka neizvi, hausi wega. Kudzoka muzuva remufirimu, vanhu vazhinji vanosarudza 100 kana 400 kumhanya kwefirimu. Wakaudzwa kuti ushandise zana kunze uye mazana mana mumba. Ichi ichiri chokwadi. Makamera anhasi edhijitari, zvisinei tipe iyo yakakura kwazvo ISO renji kupfuura firimu yakamboita. Yakawanda kamera yedhijitari inokupa iwe huwandu hwe100 kusvika 400 uye yepamusoro. Mamwe emakamera matsva anoenda kumusoro se100.

Iyo ISO ndiyo yandinowanzo gadza pakutanga kana ndichisarudza yangu yekuratidzira marongero. Heano mashoma zviitiko.

• Pandinenge ndichishanda panze, semuenzaniso, paki ine muchato kana portrait musangano, musangano wekubatanidzwa kana musangano wemhuri, ini handidi yakakwira ISO. Ini ndinoshandisa zana. Inguva chete yandingasarudze mazana maviri ndeyekuti zvakanyanyisa kukandirwa kana kuswedera padhuze pandinogona kuda kunzwisisika zvishoma kuti ndiwane mukana wangu wakanaka.
• Zvino, kana ndiri kushanda mune yakaderera mwenje mamiriro, semuenzaniso, chechi isingabvumidze kupenya kutora mifananidzo, ini ndinosarudza ISO ye800, 1600, inogona 2500. Iko kunzwisisika kwepamusoro kweiyo sensor kuchanditendera kuti ndichengete yangu F-Mira uye SS uko kwandinoda kuti vagadzire kuratidzwa kwangu kwakanaka mune iyo mamiriro emwenje.
• Ngatitii ndinoda kushanda neinowanikwa mwenje mwenje. Mwenje wewindow wakapararira (wezhinji chikamu) mwenje wezuva. Ini ndichaenda ne400 pamwe 800 kana iwo mwenje usina kunyanyisa zvakakwana sezuva rine makore. Zvekare, kumisikidza yangu F-Mira uye SS pandakangowana ISO rangu.

Kudzokorora zvishoma: Shandisa yakaderera ISO mune yakajeka mwenje mamiriro (100). Mune yakaderera mwenje mamiriro, shandisa yakakwira ISO (400, 800, 1600). Paunenge iwe wasarudza pane yako ISO, iwe unogona kupfuura kumisikidza yako SS uye F-Stop.

Ndinovimba izvi zvinokupa iri nani zano rekuti ISO inoshanda sei uye kuti ungashandise sei ISO kukubatsira. Dzidzo ndiyo kiyi. Paunenge iwe uine iyo dzidzo, hapana kumira basa rinogutsa rekutora mifananidzo. Dzidzo haife yakapera, hapana munhu mumwe anoziva zvese.

Inotevera nguva isu titarise F-Stop.
