Explained: stopping down
Finding the sweet spot of sharpness
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.
