365/117 Macro/3

You won't be able to tell much detail from the small size here (500px wide, the "original" is 1000px wide), but I took this one just to demonstrate how shallow DOF can get in the macro world. The selected aperture was barely enough to get a whole grain of salt in focus.

Lens and camera settings:
50mm f/2.0 @ f/3.2, 1/100sec and ISO 400.
