Hi, in class we were talking about lenses and how there is a certain focal length where all images 'far enough' away are in focus. I was doing some wikipedia searching and found the hyperfocal distance. Is that what this is?
I was also reading somewhere about near/far-field. from what i understand the far field is when light comes in perfectly parallel, but this usually takes a very long distance (light years). These two phenomena are not related are they? (hyperfocal distance and the far field) i mean, the idea behind the hyperfocal distance is not the angle at which the light meets the lens, correct?
