INSIGHT

Aperture Is A Hole Like Your Pupil

Aperture is simply a hole in the lens that controls how much light passes through to the sensor.
Think of the lens like the human eye: the iris changes pupil size to regulate incoming light.

INSIGHT

Aperture Controls Depth Of Field

Aperture also controls depth of field: wider apertures give shallower focus.
A large hole isolates the subject while foreground and background blur more.

ADVICE

Read Aperture Numbers As Light Steps

Learn your lens markings: numbers like 1.4, 2.8, 8 show aperture stops.
Each full f-stop change halves or doubles the light entering the lens.

We encourage you to put your camera put your camera into aperture priority mode (A for Nikon and AV for Canon) set you lens the the smallest aperture number your camera will allow you to. Shoot everything you can for an hour. Shoot things up close, shoot things far away, shoot everything in the middle. Once you're done, change your aperture to F8 and take all the same photos at the new aperture so when you put them on your computer you can see directly the differences in the photos.
