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’.

LOWER F-STOP (i.e. F1.8)LOWER F-STOP (i.e. F1.8)ADVANTAGESADVANTAGES Lets plenty of light in! Better to use in Lets plenty of light in! Better to use in
darker settings.darker settings. Less blurry since faster shutter speed Less blurry since faster shutter speed
may be needed to compensate for may be needed to compensate for more light.more light.
