Drops of Rain, photo by Harold Davis. View this image larger.

Another water drop photo from the other morning…to get this one I combined shots with several different focus points. Depth-of-field is astoundingly shallow when you get really close, and sometimes you need more than one capture to get a fair degree of focus, even with the lens fully stopped down.

Each exposure with my 200mm macro and 36mm extension tube: 4/5 of a second and f/36 and ISO 100.

This technique is sometimes called “focus stacking,” or as I’ve dubbed it HFR—High Focus Range—photography. You can read my explanation of HFR by following this link.
