I call myself a street photographer. Street photography is my drug of choice and I spend hours getting high on it. You don't need formal qualifications; you don't have to apply for membership of a professional body. All you need is a pair of comfortable walking shoes, time to walk the streets where you live, and a camera. A mobile phone would do! Mobile phones are our constant companions these days. and you don't have to look too far to see someone using one. For the next one hundred days I will be displaying some of the people using mobiles I have 'shot' as I walk the streets in my city.
