PHOTOGRAPHY 101 – What is an aperture?

The aperture is an opening inside the lens, which increases or decreases the amount of light allowed through.

 

A wide aperture means there is a bigger hole in the lens, e.g. f2.8, f2, f1.4.   The wider the aperture, the more light goes through the lens. This also results in a shallow depth of field (less things in front and behind the subject will be in sharp).

 

A small aperture means there is a small hole in the lens e.g. f11, f16, f22. The smaller the aperture, the less light goes through the lens. This also results in a longer depth of field (more things in front and behind the subject will be sharp).
