Nyob rau hauv lwm yam lus - tus nqi ntawm lub qhov nyob rau hauv lub lens. Tus me dua cov aperture, lub loj bore nyob rau hauv lub lens, cov ntau lub teeb uas nkag mus rau hauv matrix.

Excerpt. Nyob rau hauv txoj kev ntawm lub teeb dhau los ntawm lub lens mus rau lub matrix, muaj thiaj li hu ua "dig muag", uas zoo li lub diaphragm, yog taub txua nqi ntawm lub teeb, tab sis tsis yog lub qhov taub thiab raug lub sij hawm ntawm lub photosensitive caij. Shutters yog cov sib txawv - txhua yam thiab hluav taws xob. Tom qab koj nias lub khawm shutter rau tus tub yees duab lub koob yees duab, cov shutter qhib thiab kis lub teeb nyob rau hauv svetochustvitelnuyu matrix. Tab sis nws tshwm sim heev sai sai. Raug yog ntsuas nyob rau hauv cov zauv feem ntawm vib nas this (1/250, 1/500 - shutter speeds thiab 1, 2 vib nas this los yog ntau tshaj -. Ntev ntev ntaug, thiab lwm yam).

Raug - yog hais tias peb coj lub feem ntau yooj yim thiab, nyob rau hauv Feem ntau, nws yog tus nqi ntawm lub teeb yuav tsum tau rau cov ntaubntawv povthawj siv cov dluab nyob svetochustvitelnom caij nrog ib tug muab rhiab heev, proportional tu tub tu kiv ntawm brightness, tib yam li hais tias ntawm cov kev kawm. Rau qhov yuav tsum tau npaum li cas ntawm lub teeb raws nkaus Ii mus rau lub thiaj li hu ua ekspopara - aperture / shutter ceev. (Yog hais tias luv luv raug - lub aperture tus nqi yog nce, thiab vice versa, yog tias ib tug ntev raug - lub aperture nqi txo)

Nyob rau hauv niaj hnub cov koob yees duab muab xam ekspopary caw kaw lus. Nyob rau hauv kev tej zaum nws yuav nkaus phau ntawv los yog cov suab.

Yog li ntawd nws yog zoo dua mus xaiv tus nqi qis tshaj ISO, thiab tsis txhob ua kom nws tsis tsim nyog li.

Zoo, tam sim no qhov tseem ceeb tshaj kev sib raug zoo ntawm no peb tsis. Rau prostate piav qhia piav qhia txog nyob rau hauv yooj yim piv txwv, tsis muaj mus rau hauv lub kev txhawb.

Wb hais tias koj xav mus muab ib daim duab ntawm ib tug me nyuam txoj kev ua si, uas tso nyob rau hauv lub chav tsev nrog daylight. Yuav ua li cas yuav muaj kev kab tshoob thiab tsev neeg yees duab.
