Dzokera kuBasics Photography: Kufambidzana Pakati peIO, Shutter Speed ​​uye F-Stop

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 chechipiri mune dzino zvakateedzana. John anogara achishanyira iyo MCP Facebook Nharaunda Boka. Ita shuwa yekujoinha - ndeye mahara uye ine ruzivo rwakawanda kwazvo.

Muchinyorwa chedu chekupedzisira ndakakupa pfungwa yakajairika yekuti iyo exposure triangle inoshanda pamwechete. Ino nguva tichaenda mune zvakadzama pane iko kubatana.

Kutanga zvishoma zvakadzama pane chimwe nechimwe chezvinhu zvitatu zvekuratidzwa;

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.

Shutter kumhanya inguva iyo shutter yakavhurika ichibvumira mwenje kurova sensor. Iyo inononoka iyo shutter kumhanya (1/15, 1/30) iyo yakareba mwenje inorova iyo sensor. Iyo inokurumidza iyo shutter kumhanya (1/125, 1/250) iyo ipfupi mwenje inorova iyo sensor.

F-Mira kuvhura kwemukova. Kuvhura uko mwenje kunopfuura kuburikidza nenzira yeku sensor. F-Stop inodzora huwandu hwechiedza chinosvika pane iyo sensor Uye kudzika kwemunda (DOF). DOF ndiyo nzvimbo yekutarisisa kwechifananidzo. Iyo yepazasi iyo F-nhamba (1.4, 2.8) yakawedzera kuzarura, isina kudzika iyo DOF. Iyo yakakwira iyo F-nhamba (8, 11) iyo yakadzikira iyo kuzarura, iyo yakakura iyo DOF.

Iye zvino zvaunoziva zvinoita chimwe nechimwe chezvinhu izvi paunenge uchigadzira mufananidzo, ngatitarisei nzira yekuona maratidziro ako ekuratidzira.

Maitiro ekuona ako ekuratidzira marongero: Imwe nzira yekuita izvi.

Yangu sarudzo ndeyekusarudza pane yangu ISO kutanga. Sezvo ISO iri yekunzwa kweiyo sensor kune mwenje, mune yakajeka mwenje zviitiko, senge kunze muchiedza chezuva, pamhenderekedzo yegungwa kana paki ini ndinosarudza yakaderera ISO, 100. Kana iri zuva rine mafashama pamwe 200. Panenge panenge pasina chikonzero che kuve pane yakakwira ISO mumasikati mwenje zviitiko. Panogona kunge paine kusarudzika. Semitemo yakajairwa zana kana mazana maviri inofanirwa kuita zvakanaka kunze muzviitiko zvakawanda. Munzvimbo dzakadzika dzemwenje, manheru, kuswedera kwemadekwana, ndinogona kusarudza mazana mana, zvingangoita mazana masere, zvichienderana nehuwandu hwechiedza chiripo Mumba ndaizosarudza mazana mana neshamhu ingangoita 100 kana ndaida kuona mwenje wechiedza, pamwe 200, kunyangwe kana ndiri kushanda nemwenje uripo, senge muchechi isingabvumidze kupora mifananidzo.

Kana ndangosarudza yangu ISO, ini ndinosarudza paDepth yeMunda (DOF) yandinoda. Ndinoda here isina kudzika DOF, (F-2.8, 4.0) kana yakadzika DOF (F-11 kana yakakwira). Kana ndichinge ndaita sarudzo iyi zvese zvandinofanira kuita kumisikidza yangu Shutter Speed ​​kubva pane iwo marongero maviri, yangu F-Stop uye ISO. Kana ndangomisa yangu Shutter Speed, ndichaita mashoma ekuyera mifananidzo kuti ndive nechokwadi chekuti kufumurwa kwangu kwakarurama, kana zvisiri, ndichaita zvigadziriso zvidiki kuti ndiwane mukana wakanaka.

Ndinovimba izvi zvinokupa iwe zvakadzama kutarisa kutarisa kwedu katatu. Enda unodzidzira. Tora mubato wakanaka pamaitiro ekuti Triangle yekuratidzira inoshanda sei. Ita izvozvo uye uchave uri munzira yako yekugadzira mifananidzo mikuru isingadi kugadziriswa, kungogadziridza kwekugadzira. Sekuenderera mberi kwezvinyorwa zvedu, isu tichaenda mune yakadzama pane yekuratidzwa katatu.
