Dzokera kuBasics Photography: Chii chinonzi STOP OF LIGHT?

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 chechinomwe munhevedzano iyi. John anogara achishanyira iyo MCP Facebook Nharaunda Boka. Ita shuwa yekujoinha - ndeye mahara uye ine ruzivo rwakawanda kwazvo.

Chii chinonzi "kumira kwechiedza" uye nei ndichifanira kuziva izvi?

Takatarisa kuIO, F-Stop uye yekupedzisira Shutter Speed. Takatarisa kuti mumwe nemumwe ane sei mhedzisiro pane yekuratidzwa katatu. Pane chimwezve chinhu chandingade kubata nacho.

Ndine chokwadi chekuti wakanzwa chirevo "kumira kwechiedza." Kumira kwechiedza ndiko mutsauko muhuwandu hwechiedza hunosvika pakona pakati peF-Stops.

Imwe F-Mira:

Kana iwe ukatama kubva paF4 uchienda kuF5.6 iwe wakadzikisa huwandu hwechiedza chinosvika kune sensor ne1 F-Stop. Rangarira, iyo yakakwira iyo F nhamba iyo idiki iyo yekuvhura kuvhura. Nguva imwe neimwe paunokwira kumusoro imwe F-Stop iwe uri kucheka huwandu hwechiedza hunosvika kune sensor muhafu. Izvo zvinopesana ndezvechokwadi. Rangarira, iyo yakaderera iyo F nhamba iyo yakakura iyo yekuvhura kuvhura. Nguva imwe neimwe paunodzika pasi imwe F-Mira iwe uri kuwedzera huwandu hwechiedza unosvika kune iyo sensor, uchipeta mwenje zvakapetwa.

Kumira neIO:

Yako ISO inoshanda nenzira yakafanana. Imwe neimwe inokwira kumusoro kana pasi muIO yekumisikidza kungave kuwedzera kana kuderera kwechiedza kwakaenzana kumisa kwechiedza. Semuenzaniso: 100 kusvika 200 kumira kumwe kwechiedza. 200 kusvika 400 kumisa kumwe kwechiedza. 400 kusvika 800, imwe yekumira, 800 kusvika 1600, imwe yekumira. Nekudaro, kana iwe ukatama kubva kuIO 100 kuenda kuIO 400, wakawedzera iwe kuratidzwa nemitobvu miviri. (100 kusvika 200 ipapo 200 kusvika 400).

Kumira neShutter Speed:

Yako Shutter Speed ​​inoshanda mune imwechete fashoni zvakare. Shanduko yega yega muShutter Speed ​​yakaenzana nekumira kwechiedza. Semuenzaniso: 1/30 kusvika 1/60 imwe chete yekumira. 1/15 kusvika 1/30 kumira kumwe. 1/30 kusvika 1/60 kumira kumwe. 1/60 kusvika 1/125 kumira kumwe. 1/125 kusvika 1/250 kumira kumwe, 1/250 kusvika 1/500 kumira kumwe. Kana iwe ukawedzera yako Shutter Speed ​​iwe uri kucheka kwenguva mwenje inosvika kune sensor nekumira kumwe. Kana iwe ukatapudza iyo SS iwe uri kuwedzera iyo yakareba mwenje inosvika kune sensor kamera nekumira kumwe.

Kune masvomhu anobatanidzwa mune zvese izvi. Iwe haudi kunyatso kuziva izvozvo, ingo ziva kuti kufamba kwese kune chero zvikamu zvitatu zvezvikamu zvekuratidzwa katatu ndiko kumira kumwe kwechiedza, kungave kuwedzera kana kuderera.

Shanduko imwe neimwe mune imwe yevatatu inoripirwa neshanduko mune imwe chete yevamwe vaviri. Rangarira, verenga chinomira shanduko.

• * Imwe yekumira shanduko muIO inoda imwe yekumira shanduko mune chero SS kana FStop kuchengetedza zvakafanana kuratidzwa.
• * Imwe yekumira shanduko muSS inoda imwe yekumira shanduko mune chero ISO kana FStop kuchengetedza zvakafanana kuratidzwa.
• * Imwe chete yekumira shanduko muF-Stop inoda imwe chete yekumira shanduko mune chero SS kana ISO kuchengetedza zvakafanana kuburitswa.

Heano muenzaniso:

Unovhiringika zvakadaro? Ndinovimba kwete. Chinyorwa chedu chinotevera chinosungira izvi zvese kwauri.
