Rocks in Water

IMGP1712a
50mm prime, f/1.8, ISO 100, 1/8000s

I find it interesting that the reflections on the top half of the image are green and the reflections on the bottom half are purple.  I presume it has to do with the chromatic aberration in the lens.

The wide-open aperture and a short object-distance resulted in the very slim depth of field.
