Kuidas ava seadistus, säriaeg ja ISO tundlikkus kontrollivad säritust

Ava seadistus, säriaeg ja ISO tundlikkus on fotograafias omavahel tihedalt seotud. Ava seadistus kontrollib avanemist, mis reguleerib valgust, mis siseneb kaamerasse ajal, kui säriaeg määrab aja pikkuse, mille jooksul valgust sisse lastakse. ISO tundlikkus määrab kiiruse, millega film reageerib valgusele. Neid kolme aspekti kirjeldatakse kui särituse kolmnurka.

Muutusi säriajas, ava väärtuses või ISO tundlikkuses saab hüvitada muudatustega teistes, et säilitada valguse hulk. Tulemused muutuvad vastavalt seadistustele. Näiteks, säriaeg on kasulik liikumise väljendamisel, ava saab kontrollida teravussügavust ja ISO tundlikkus foto teralisust.
