What is aperture? VERSUS

The most obvious advantage of a wider aperture is the ability to take photos in darker environments; what is not so simple is the fact that a lower number means a wider aperture. Aperture is measured in f-stops, and as an example, an f/1.4 aperture can let more light in than an f/2.8 aperture.
