Well, at least this couple will have a redundant backup system for their treasured memories.
But let's look a little beyond them.
When you sail into Sydney Harbour (should you be foolish or suicidal enough to board a vessel), you don't just point it west through the harbour's headlands and hit the throttle. For you see, Sydney Harbour doesn't have two headlands. It has the north head (which you see coming in from the left), it has the south head (which you can't see at all in this shot)... and you have Middle Head, which is a piece of land jutting straight out toward the entrance of the harbour and which you will run smack bang into if you're not expecting it. (Though it'd be hard to miss; that's a bit of it on the right.) It essentially divides the entrance of the harbour into two branches; the main southern branch (which is Port Jackson, leading on to the Harbour Bridge, Opera House, and the Harbour As You Would Know It), and the northern branch which is Middle Harbour, running past Balmoral.
This might have actually been a decent shot with some good light, but it's been mostly grey and overcast for a few days now. Blah.
