Focus stacking for sharp shots
‘Focus stacking is commonly used to achieve wide depth of focus in situations where it would otherwise be unachievable.’
Focus stacking is a technique that combines a series of images taken at different focus distances to give a resulting image with a greater depth of field than any of the individual shots. It is commonly used to achieve wide depth of focus in situations where it would otherwise be unachievable, most commonly in macro photography, where depth of field is generally limited.
When shooting for focus stacking, photographers can select a wide lens aperture (which will usually deliver maximum sharpness at the focus point) and record a wide depth of focus without diffraction. This isn't possible when the lens is stopped down. Focus stacking can also be useful for landscape and architectural photography to overcome diffraction effects when very small apertures are used to obtain maximum depth of field. It also enables use of low ISO settings with wide apertures when shooting in low light levels.
While focus stacking has been around for a long time, it has
