A macro photo of an agate slice:
Approximately 3x lifesized, 56 stacked images. Backlit. There is not much point in focus stacking something relatively flat like this - but moving the focal plane into the semi-transparent rock slice does seem to bring out some details and structures that enhance the image. And stacking also spared me from having to align the stone to the camera's focal plane.
