Focus stacking
From Wikipedia, the free encyclopedia
Focus stacking is a digital image processing technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images.
Getting sufficient depth of field can be particularly challenging in macro photography. The images at right illustrate the increase in DOF that can be achieved by combining multiple exposures.
Other digital imaging techniques used to increase DOF include wavefront coding and plenoptic cameras.
