And if you know anything about me at this point, you know I'm down for a physics discussion. We start with diffraction — the optical phenomenon that makes f/22 softer than f/8, even though everything is technically "in focus." When light is forced through a tiny aperture opening, it bends and spreads rather than travelling cl...
