HOW MUCH LIGHT IS SEENHOW MUCH LIGHT IS SEEN Sometimes known as ‘aperture’Sometimes known as ‘aperture’ Ranges from about 1.8 to 32Ranges from about 1.8 to 32 A higher number (i.e. 32) means less A higher number (i.e. 32) means less

light is ‘seen’.light is ‘seen’. A lower number (i.e. 1.8) means A lower number (i.e. 1.8) means

more light is ‘seen’.more light is ‘seen’.
