What Aperture Does, In Two Photos

The views expressed are those of the author and are not necessarily those of Scientific American.

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.

    I know from corresponding with Scientific American, that they don’t pay their bloggers very much.

    In this case, they got even less than they paid for.

    Seriously, 2 photos, no explanation of focal depth or reduced light to the sensor? You certainly know how to teach photography! /sarcasm

    I don’t know, the pictures say it all, little explanation needed. This is provides more info to my brain than several paragraphs of text.
