A photographer with any skillz whatsover (ie, not me) could make this look fantastically dramatic I reckon.
The graffiti throw-up is in the empty void where there used to be a water reservoir at the top of Symonds St. The church behind it is on Khyber Pass.
I like the contrast between the prim (yet unusually coloured) church and the energetic writing. But this tableau, which I've passed numerous times, also reminds me that both religion and "tagging" have something in common: they're both easy targets at the moment. Religion is portrayed as the butt of cheap jokes (at best) rather than a phenomenon worth explaining; tagging (which the piece above isn't really an example of) can get you killed.
Maybe the world is divided into two types of people: those who think tagging is worse than religion and those who think religion is worse than tagging...
