Ukuqonda I-Aperture, Isantya Se-Shutter, kunye ne-ISO
Published:
1. I-Aperture
I-Aperture ilawula ubunzulu bentsimi kunye nesixa sokukhanya esingena kwi-lens. Ilinganiswa ngee-f-stops (umz. f/1.8, f/8, f/16).
- Ukuvula okubanzi (inani elincinci le-f, umz. f/1.8): Ivumela ukukhanya okuninzi, yenza imvelaphi emfiliba (ubunzulu obungephi bentsimi). Ilungele imifanekiso.
- Ukuvula okucutheneyo (inani elikhulu le-f, umz. f/16): Ivumela ukukhanya okuncinci, igcina yonke into ukusuka ngaphambili ukuya ngasemva ibukhali (ubunzulu obukhulu bentsimi). Ilungele imihlaba.
Ingcebiso Ye-Pro
Cinga nge-aperture njengo mfundi weliso lakho. Iyanda (iba nkulu) ebumnyameni kunye nezivumelwano (ziba zincinci) ekukhanyeni okukhulu.
2. Isantya Se-Shutter
Isantya se-shutter bubude bexesha i-shutter yekhamera yakho ihlala ivulekile. Ilawula ukuswela intshukumo.
- Isantya esikhawulezayo (umz. 1/1000s): Iqina isenzo esikhawulezayo (imidlalo, izilwanyana zasendle).
- Isantya esicothayo (umz. 1s nangaphezulu): Intshukumo emfiliba (iingxangxasi zesilika, imizila yokukhanya). Ifuna i-tripod.
3. ISO
I-ISO ilinganisa ubuntununtunu bekhamera yakho ekukhanyeni.
- I-ISO ephantsi (umz. 100): Umgangatho ogqibeleleyo, “ingxolo” encinci (incochoyi). Sebenzisa oku ekukhanyeni okukhulu.
- I-ISO ephezulu (umz. 3200 nangaphezulu): Ikuvumela ukuba udubule kwisibane esiphantsi, kodwa yongeza ingxolo yedijithali emfanekisweni.

Indlela Abasebenza Ngayo Kunye
Oku kubizwa ngokuba yi “Exposure Triangle”. Ukuba utshintsha useto olunye, luchaphazela ezinye.
- Ukuba wandisa indawo yakho yokuvula (vumela ukukhanya okungakumbi), ufuna isantya esikhawulezayo se-shutter okanye i-ISO ephantsi ukugcina ukuvezwa okufanayo.
- Ukuba ufuna isantya sokucima ngokukhawuleza ukuze ubandise isenzo, kungafuneka wandise i-ISO yakho okanye uvule i-aperture yakho.
