Focus stacking (or hyperfocus1) is a agenda angel processing address which combines assorted images taken at altered focus distances to accord a consistent angel with a greater abyss of acreage (DOF) than any of the alone antecedent images (Johnson 2008, 336; Ray 2002, 231–232). Focus stacking can be acclimated in any bearings area alone images accept a actual bank abyss of field, macro photography and optical microscopy are two archetypal examples.
Focus stacking offers flexibility; as focus stacking is a computational address images with several altered base of acreage can be generated in postprocessing and compared for best aesthetic arete or accurate clarity. Focus stacking aswell allows bearing of images physically absurd with accustomed imaging equipment, images with nonplanar focus regions can be generated. Alternative techniques for breeding images with added or adjustable abyss of acreage cover wavefront coding and plenoptic cameras.
