Dubinska oštrina

dubinska oštrina, polje dubinske oštrinePolje dubinske oštrine nema naglu promenu iz oštrog u zamućeno, promena je postepena. U stvari, sve ispred ili iza fokusne ravni više nije oštro, čak iako to naše oči ili fotoaparat ne vide – zbog toga govorimo o fokusnim ravnima u kojima je oštrina još uvek prihvatljiva.

Polje dubinske oštrine

    Depth of field refers to the section of a photograph that appears to be in sharp focus.
John Shaw’s Nature Photography Field Guide, John Shaw, 2000

The depth of field is defined as the area in front of and behind the subject that is in acceptable focus.
Night and Low-Light Photography Workshop, Alan Hess, 2011

When an object is in focus, everything from a certain distance in front of the object to a certain distance behind the object will also be in reasonably sharp focus. This distance from front to back that will be in reasonably sharp focus is called the depth of field.
How to Use Your Camera, New York Institute of Photography, 2000.

Depth of Field (DOF) is the range of distance in a photo that appears to be in sharp focus … Depth of field is a creative decision and one of your most important choices when composing nature photographs.
Nature Photography Photo Workshop, Nat Coalson, 2011
