Part 2 How to use me­ter­ing

When to use par­tial or spot me­ter­ing to get more pre­cise read­ings

Digital Camera World - - DIAL M FOR MANUAL -

Your cam­era’s me­ter­ing sys­tem will of­fer a choice of modes for use when tak­ing ex­po­sure read­ings. Although the names vary slightly from man­u­fac­turer to man­u­fac­turer (Pat­tern me­ter­ing is also known as Eval­u­a­tive or Ma­trix), the modes are de­signed to of­fer vary­ing amounts of pre­ci­sion.

Pat­tern me­ter­ing is of­ten the de­fault mode for many pho­tog­ra­phers, and gets it right most of the time. It me­ters the whole scene in the viewfinder, but adds weight­ing to what is be­ing fo­cused on. The cam­era takes a wide range of read­ings across the scene, com­pares them to im­ages in its mem­ory then ef­fec­tively ap­plies its own ex­po­sure com­pen­sa­tion.

Cen­tre-Weighted takes a read­ing across the whole scene, but places more em­pha­sis on sub­jects sit­u­ated in the mid­dle of the frame. Use it for sce­nar­ios when the sub­ject you’re pho­tograph­ing is back­lit (as­sum­ing it’s in the cen­tre of the frame, of course).

If you need pin-point pre­ci­sion, Spot me­ter­ing is the one to go for – if you’re pho­tograph­ing a light sub­ject against a dark back­ground, for ex­am­ple. The spot me­ter will typ­i­cally be fixed at the cen­tre AF point, but some cam­era me­ter­ing sys­tems can spot-me­ter from off-cen­tre AF points.
