On a bright and clear Bangalore evening, a handful of photographers turned up at Church Street, plastering the pristine white walls outside Coconut Grove with photographic prints.

Some of the photographs went up on a giant electricity transformer cage next to Barton Centre, a few were incongruously pasted against graffiti on the walls, next to a street side chaat wala.

The photographs were of unlikely men on children swings, construction debris and tin sheets scarring the streets, a traffic cone with unlikely hands, feet and a briefcase, the shadow of a dog in a city that is quickly becoming a shadow of itself.

People stopped by to look at the 100-odd prints. They smiled, shook their heads in disbelief, some grabbed a pani puri from the nearby chaat vendor and mulled over the images, others left their smudgy finger prints on the pictures.

In 30 minutes the open air exhibition had clocked in an audience several fold larger than what an art gallery would have seen in a week. That was the first Blow-Up by the Blind Boys, a community of like-minded people with the firm belief that opportunities should be available to everyone - an alternative to the traditional photograph, from its moment of creation to its consumption.

A Blow-Up is an improvised street exhibition where everyone is invited to come and display their work on the streets together with other photographers. Over the past four months, Blind Boys has organized three Blow-Ups in Bangalore, Paris and Delhi, displaying works from over 15 photographers and 2500 pictures.

Many more Blow-Ups are planned, all you have to do is follow the Blind Boys and show up to get your share of open air photography and art excitement.
