The unfortunate thing about this shot is that I took my travel tripod on this trip (2 weeks of work + leisure combined, so had to pack light). And unfortunately, the tripod did not extend enough to clear the glass and railing of the Tour Montparnasse terrace. So I ended up having shoot hand-held at f/1.6 to get anything usable.

No such problems on the Amalfi pier.
