key con­cept Make sens e of man ual

Man­ual ex­po­sure sounds com­plex, but it’s ac­tu­ally rather sim­ple

NPhoto - - Special Feature -

Your Nikon D-SLR uses three key ex­po­sure set­tings: shut­ter speed, lens aper­ture and ISO (sen­si­tiv­ity), and the set­tings have been de­signed in a very clever way – you can bal­ance one against an­other. If you want to use a faster shut­ter speed, you can in­crease the lens aper­ture set­ting. This al­lows more light through to com­pen­sate for the shorter ex­po­sure. Al­ter­na­tively, if the light is too dim for the shut­ter speed you want to use, and you’re al­ready us­ing the lens’s max­i­mum aper­ture, you can in­crease the ISO set­ting to com­pen­sate for the dimmer light.
