Go­ing deep

When ev­ery­thing is sharp from front to back, it height­ens the sense of re­al­ity

Even though fo­cal length per se has almost noth­ing to do with depth of field (see right), one way to en­sure front-to-back sharp­ness is to use a wide-an­gle lens, pro­vided that it’s stopped down to a small aper­ture, like f/16 or f/22.

The tech­nique re­ally re­lies on view­point and com­po­si­tion, with a close fore­ground and a view in the dis­tance, and both ends of the scale ar­ranged in the frame so they re­late to each other. Ansel Adams, a master of this tech­nique, called it the ‘Near-Far’ ap­proach. Sharp­ness that ex­tends from the front to the back of the frame height­ens the sense of re­al­ity, and gives the viewer the sense of be­ing able to touch ev­ery part of the scene.
