Nekugadzirisa yako ISO marongero unogona kuwedzera kana kuderedza kuwanda kwekupenya kwakatorwa zvichienderana nemamiriro ezvinhu.

Chii chinonzi ISO?

ISO inomirira International Organisation for Standardization uye igadziriso inogadzirika pane kamera inosarudza kunzwa kwe sensor. ISO mazinga anowanzo kuratidzwa senhamba dzakadai se100, 200, 400 uye inogona kubva pa50 kusvika pakakwirira se12800 kana kutokwira zvichienderana nekamera. ISO zvigadziriso zvinokanganisa kupenya kwemafoto ako uye huwandu hweruzha rwauchange uine mavari. Ngatitarisei zvakanyanya kuti zvinoshanda sei.
