In addition: does the change in the pupil size affect the way we perceive depth of field?
In: Biology
It definitely affects depth of field. It’s more of a big deal for other animals, though. Perhaps you’ve seen the “TARGET ACQUIRED” look of really huge pupils on cats right before they pounce? That’s not so they have more light necessarily, it’s more so they have a narrower depth of field around the thing they’re about to pounce on so they can make an accurate leap.
