Hello Forum,(adsbygoogle = window.adsbygoogle || []).push({});

when a camera is focused at "infinity", everything from infinity on is in focus (acceptable).

How is that possible? Every plane that is not in perfect focus has a certain circle of confusion that gets larger (more blurring) as we move away from the best focus plane....

Also, what happens to the aperture stop when the camera setting is "infinity"?

thanks
