Often a major goal in macro photography is to obtain a sharp image of the subject, from front to back, with a soft, out-of-focus, non-distracting background. This can be accomplished using a method called focus stacking in which a series of photos are taken with the same camera settings while making slight changes in the focus point for each shot. Various software packages can be used to facilitate the subsequent alignment, stacking and processing required to merge only the areas in focus into a single image.
The Olympus OM-D E-M1 Mark II camera has a shooting mode (Focus Stacking) in which a single shutter activation initiates the capture of 8 sequential images, each focused at a different depth plane, which are then automatically merged into a single JPEG image.
The results of my first attempt to use this feature of the camera are shown here.
