Zvakaoma kutora mapikicha evanhu uye kufamba kwakawanda kwenguva yakareba, uyezve, iwe unogona kuzunungusa uye uine blurry mhedzisiro. Iyo ISO yepamusoro, kune rumwe rutivi, inogona kutungamira kune yakakura huwandu hweruzha nekuti iwe uri kunyatso kuita kuti sensor iwedzere kutarisisa kune mwenje wausiri kuwana, zvichitungamira kudhijitari aberration.
Saizi yeaperture inokonzeresa kudzika kwemunda, izvo zvinoguma nehukuru kana hudiki bokeh, i.e. kuparadzaniswa kwechinyorwa kubva kumashure.
