Frequently Asked Questions
What is hyperfocal distance?
The hyperfocal distance is the focus distance that produces the maximum depth of field, rendering everything from half the hyperfocal distance to infinity in acceptable focus.
Why does a wider aperture produce shallower depth of field?
Wider apertures (like f/1.4 or f/1.8) allow light rays to enter at steeper angles, causing out-of-focus points to blur into larger circles of confusion.
