What is "combinez"

CombineZ is Free software image processing software package for creating extended depth of field images. It runs on Microsoft Windows. The current release is CombineZP (CombineZ-Pyramid), successor to CombineZM (CombineZ-Movie) which was based on CombineZ5 (designed for older versions of Windows and is no longer maintained).

CombineZ processes a stack of images (or "Frames") and is most frequently used to blend the focused areas of several partially focused digital photographs in order to create a composite image with an extended depth of field (DOF), created from the in-focus areas of each image.
