What Aperture Does, In Two Photos

|

Curious about why you'd want to pay attention to that f/number on your camera settings? Consider:

An Ecuadorian Ectatomma ant photographed with the aperture wide open, f/2.8

The same ant photographed with the aperture closed down to f/13. The flash power was turned up to compensate.

Same subject, same lens, same camera, very different image.
