Effect of Aperture The aperture increases or reduces the amount of reflected light from an object through the lens, controlling how much light strikes the film. lf the aperture is opened up to increasethe amount of light, objects in front of and behind an in-focus subject will not be focused. That is, the range of focus (depth of field) becomes small. lf the aperture is closed down to reduce the amount of light, the depth of field increases. For example, if you shoot a person against a landscape with the aperture open, the landscape in front of and behind the person will be blurred, making the person a p p e a r t o r i s e o u t o f t h e l a n d s c a p e .
