Ukuqonda I-Aperture, Isivinini Se-Shutter, ne-ISO

1. I-Aperture

I-Aperture ilawula ukujula kwensimu nenani lokukhanya okungena kulensi. Kukalwa nge-f-stops (isb. f/1.8, f/8, f/16).

• Ukuvuleka okubanzi (inombolo encane ye-f, isb. f/1.8): Ivumela ukukhanya okuningi, idala ingemuva elifiphele (ukujula okungajulile kwensimu). Kuhle ngemidwebo.
• Ukuvuleka okuncane (inombolo enkulu ye-f, isb. f/16): Ivumela ukukhanya okuncane, kugcina konke kusuka ngaphambili kuye ngemuva kubukhali (ukujula okukhulu kwensimu). Kuhle ngendawo.

2. Isivinini Se-Shutter

Isivinini se-shutter ubude besikhathi lapho i-shutter yekhamera yakho ihlala ivulekile. Ilawula ukufiphaza ukunyakaza.

• Isivinini esisheshayo (isb. 1/1000s): Iqina isenzo esisheshayo (ezemidlalo, izilwane zasendle).
• Isivinini esihamba kancane (isb. 1s noma ngaphezulu): Ukunyakaza okufiphaza (izimpophoma zikasilika, imikhondo yokukhanya). Kudinga i-tripod.

3. ISO

I-ISO ikala ukuzwela kwekhamera yakho ekukhanyeni.

• I-ISO ephansi (isb. 100): Ikhwalithi engcono kakhulu, “umsindo” omncane (okusalungiswa). Sebenzisa lokhu ekukhanyeni okukhulu.
• I-ISO ephezulu (isb. 3200 noma ngaphezulu): Ikuvumela ukuthi udubule ekukhanyeni okuphansi, kepha ungeza umsindo wedijithali esithombeni.

Basebenza Kanjani Ndawonye

Lokhu kubizwa nge- “Exposure Triangle”. Uma ushintsha isethingi eyodwa, kuthinta ezinye.

• Uma wandisa ukuvula kwakho (vumela ukukhanya okwengeziwe), udinga isivinini esisheshayo se-shutter noma i-ISO ekhansi ukuze ugcine ukuvezwa okufanayo.
• Uma ufuna isivinini se-shutter esisheshayo ukuze ubandise isenzo, kungahle kudingeke ukuthi wandise i-ISO yakho noma uvule i-aperture yakho.
