Straddle Carriers

These quirky machines are called straddle carriers, and oddly enough, they straddle and carry. They're used for stacking containers in long rows (often referred to as the 'stacks') and in some ports they drop the containers off for the cranes to load them onboard our good ship.

Particularly proud of this shot, as I want to get the foremost carrier focussed and the background all blurry. I'm sure there's a technical term for that. Depth of field, perhaps?
