Photography details: All of the photos in this database were captured with the Macropod.

The Macropod is a rigid, transportable photomacrography technique, which enables the user to make razor sharp, completely focused photographs of small sized specimens at 18 to 26-megapixel resolution. It overcomes the extreme Depth of Field (DOF) limitations inherent in optics made to image smaller sized specimens. Usually, lenses developed for macro will only render a really small fraction of the depth of targeted specimen in sharp focus at any a single exposure. The Macropod makes it possible for the user to choose and make a number of exposures in precise increments along the Z-axis (depth) such that each exposure’s region of sharp concentrate overlaps with the preceding and next exposure. These source pictures are then transferred to a computer and merged by an image-stacking program. Zerene Stacker is utilized to find and stitch with each other only the focused pixels from each and every exposure into one image. The Macropod integrates industry-major elements in a novel and sophisticated way to achieve these results.
