This is just a beautiful image. The rovers can't step back and take photos of themselves, but once in a while they do the next best thing, capturing themselves in silhouette in a long morning or evening shadow. This one gets both the rover and most of Victoria Crater in the background.

Opportunity casts a long shadow
In this Hazcam view from sol 1607, Opportunity's late-afternoon shadow is stretched even longer because it is cast down the sloped rim of Victoria crater. The Pancam mast, high-gain (dish) antenna, and low-gain (pole) antenna all cast distinctive shadows.
