Xav txog qhov muag. Yog tias nws nyob hauv lub teeb ci nws me dua thiab yog tias nws tsaus dua nws loj dua. Aperture yeej tswj hwm qhov pom kev ntawm lub teeb. Yog tias koj muaj lub qhov tob ntawm 4.5 (Saib thawj daim duab.) Yuav muaj lub teeb pom kev ntau dua thiab yog li ISO thiab Shutter Time yuav me dua. Qhov no feem ntau txhais tau tias koj yuav tau co tsawg dua hauv daim duab tab sis muaj DOF me dua (Qhov tob ntawm Qhov Teb). Yog tias koj muaj aperture ntawm 29 (Saib duab thib ob) koj yuav tsum muaj ISO siab dua thiab Shutter Speed siab dua. Tej zaum koj yuav tau txais co ntau dua tab sis koj kuj tau txais DOF dav dua.

Kauj ruam 2: ISO

ISO tau teeb tsa uas teev tias yuav ua li cas rhiab lub koob yees duab kom pom kev. Qhov qis ISO txhais tau tias nws yuav tsaus dua. ISO siab dua txhais tau tias koj yuav muaj duab ci dua. Cov koob yees duab digital niaj hnub no yuav kho lub Shutter Time thiab Aperture kom tau txais cov duab tsim nyog. Ib qho ISO siab dua yuav muab koj cov duab nkig (Thawj Duab) thaum ISO loj dua feem ntau yuav ua rau me me (Duab thib ob). Kuv siv cov teeb tsa ISO 100 thiab ISO 12800. Sim ua kom ISO tsim nyog tsawg. Yog tias koj tab tom thaij duab koj yuav xav tau ISO siab dua.

Kauj Ruam 3: Shutter Speed

Shutter speed yog lub sijhawm uas lub qhov rooj qhib. Hauv thawj daim duab lub nrawm nrawm yog 1/250 ntawm ib pliag, daim duab thib ob yog 1/2000 ntawm ob. Shutter Speed tuaj yeem siv los ua cov duab ci dua lossis tsaus dua. Ceev faj tias ntev dua lub qhov rooj qhib ntau dua qhov co koj yuav tau txais.

Kauj Ruam 4: Xaus

Koj Tau Kawm:

Shutter Ceev, ISO, Thiab Aperture.

Tam sim no mus thiab coj qee cov duab ntawm phau ntawv hom.
