Txheeb xyuas qhov matrix rau cov pixels tuag yog ib qho ntawm cov theem tseem ceeb tshaj plaws ntawm kev soj ntsuam lub koob yees duab thaum muas. Txaij nrog ntau tus txheej txheem yooj yim, koj tuaj yeem zam qhov tsis txaus siab ntau xim xim nyob hauv cov duab thiab nco ntsoov tias cov ntawv sib npaug ntawm koj lub koob yees duab yog qhov kev ua haujlwm zoo.
Cov Lus Qhia
Kauj ruam 1
Peb tau teev phau ntawv shooting hom (M).
Kauj ruam 2
Peb teeb tus nqi ISO rau 100 lossis qis dua, tig mus rau phau ntawv kom pom tseeb (MF).
Kauj ruam 3
Peb xaiv cov duab siab tshaj plaws.
Kauj ruam 4
Yog tias Tsis Muaj Hluav Taws Xob Lawm, qhib nws.
Kauj ruam 5
Peb coj li 10 txhaj tshuaj los "sov so" qhov loj.
Kauj Ruam 6
Peb kaw lub lens nrog lub hau thiab thaij duab, teeb tsa qhov ntsuas lub zog mus rau 5-10 vib nas this. Yog tias tsis muaj qhov npog, tom qab ntawd peb thaij qee qhov muag muag, so lub lens ntawm nws. Qhov loj tshaj plaws yog los xyuas kom meej ua tiav blackout.
Kauj Ruam 7
Thaum siab siab, peb ua tib zoo saib xyuas cov duab, ib kauj ruam zuj zus, tsis muaj ploj ntawm thaj chaw. Lub tswv yim, koj yuav mus nrog ib cov duab dub kiag li.
Txawm li cas los xij, ntawm cov xim dub tom qab, cov xim xim sib txuam yuav pom - faulty pixels. Muaj ob yam ntawm cov pixels xws: tawg (txias) thiab kub.
Lub thawv txias tsis ua haujlwm. Lawv yog cov tsim nyog pom ua ntej ntawm txhua yam, raws li lawv sawv tawm hauv qhov chaw ci ntsa iab ntawm daim duab. Feem ntau lawv dawb, tab sis lawv kuj tuaj yeem dub.
Cov duab kub kub tshwm sim thaum lub suab tsis txaus siab, lawv tuaj yeem liab, xiav lossis ntsuab. Lub txhoj matrix ua kom sov ntawm ISO muaj nuj nqis, lub sijhawm ntev, lossis tsuas yog vim muaj qhov kub muaj peevxwm. Ob peb tawg lossis kub xaim yog suav tias yog qhov qub, tab sis yog tias lawv tus lej ntau dua 4-5, nws yog qhov zoo dua rau tsis kam yuav lub koob yees duab. Txawm hais tias cov pixels tsis tshua pom nyob hauv cov duab, lawv yuav qhia tias muaj teeb meem nrog lub sensor. Hauv qhov no, lawv cov lej yuav nce raws sijhawm.
