Achyrachaena mollis, enhanced depth of field

Achyrachaena mollis, enhanced depth of field

To get around the fact of shallow depth of field encountered in close up photography, one technique, called "focus stacking" or "depth of field stacking" uses a series of pictures of the object, each focused slightly further "into" the object.

The slices are then merged into a single image, hopefully with the entire subject in sharp focus.
