I’ve bought a fil­ter kit that con­tains coloured and full and grad­u­ated ND fil­ters. What sub­jects will give the best re­sults? Craig Wal­lace, via email

Ja­son says... Your fil­ter kit sounds ideal for land­scape pho­tog­ra­phy, Craig. Orange fil­ters can boost the colours of sun­rise and sun­set, while grad­u­ated ND (Neu­tral Den­sity) fil­ters are de­signed to darken bright skies with­out af­fect­ing the land­scape be­low, en­abling you to cap­ture, say, sun­rises and sun­sets with­out the sky blow­ing out. Full ND fil­ters, mean­while, re­duce the amount of light reach­ing the sen­sor, which means you can set a long ex­po­sure even in very bright light – ideal if you want to blur mov­ing wa­ter or pass­ing clouds in the middle of the day.

When us­ing coloured fil­ters, use the pre­set white bal­ance set­ting that best matches the light­ing con­di­tions, for ex­am­ple Day­light, Cloudy or Shade. The Auto set­ting won’t work so well, as it will try to coun­ter­act the colour of the fil­ter. Ma­trix me­ter­ing works fine with full ND fil­ters and, to some ex­tent, with ND grads too.

For op­ti­mum ex­po­sures with ND grads, take a light read­ing of the land with no sky in the frame be­fore fit­ting the fil­ter, then set the ex­po­sure for the land in man­ual mode
