"Street photography does have a role
It speaks of our time, of society's soul
Of technology, of fashion, of societal norms
How it conflicts, how if conforms
To notions of decency, taste and behaviour
Of things that disgust, of moments to savour."
I wrote those words in 2009 as a preface to my book, Mixed Messages. They're enough to sum up what street photography is all about for me and I'm sure many others too.
