Ex­plained: stop­ping down

Find­ing the sweet spot of sharp­ness

NPhoto - - Feature -

Clos­ing the aper­ture – by di­alling in a higher f-num­ber on the cam­era – is of­ten re­ferred to as ‘stop­ping down’. All lenses have a sweet spot – an aper­ture at which the lens pro­duces the sharpest re­sults – so you might find that your kit lens gives sharper re­sults when you stop down to a mid-range aper­ture such as f/8. At f/8, you’ll need to work even harder to get that shal­low-depth-offield look, but you have all of the tech­niques de­scribed in this sec­tion at your dis­posal.
