I can't pinpoint exactly when or why Brisbane decided it was necessary to light its bridges and buildings but I approve. I rather suspect that advances in technology made it possible and then it became a case of "if you can you should".
Doubtless there are good counter arguments. It's probably not too good for the environment to light things for no reason other than aesthetics. It might even be confusing for wildlife even though the lighting levels are low.
But it makes a statement loud and clear with no volume at all. Tonight after the theatre, Oliver and I made a detour via the city for a small spot of photography. There was no-one around until one other family group pulled up. The camera revealed that their intention was the same as ours. Before the lights that would never have happened - at least not at night. It may be pointless but it's pretty and that's reason enough for me.
