An exhibition of photographs taken by the visually impaired opens this week at the Alliance Française cultural centre in Delhi. Ravi Thakur, who was born blind, took this picture. "I followed the direction of the sound of a cycle in motion but initially was confused by the sound from the sea," says Ravi. "Once I could differentiate, and then based on clues to take pictures in motion, I dared to take this picture and was lucky to get it."

This picture of pigeons in flight was taken by Bhavesh Patel, who was also born blind. "I followed the direction of the sound of pigeons flying and took the picture based on the audio clue, which meant some more pigeons are flying. It started raining a few moments after this picture was taken."

Mahesh Umrannia's photo shows a window and two harmoniums. "As a student of Indian classical music I always wanted to photograph the music room," says Mahesh.

Kanchan Pamnania took this shot during a pinhole camera photography workshop. "The pinhole camera has advantages over a normal camera. Once I have decided what to capture, the camera is placed correctly and left for long exposure. There is no need to focus or adjust exposure. What you get is a surprise," says Kanchan.

Rahul Shirshat took this picture during a photography workshop at a blind school. "By touch I know the door and chair, I can also feel the warmth of light. By measuring the space I composed this picture. The contemporary designed chair next to an old styled wooden door interested me to convey the co-existence of old and new in our lives," he says.

Ashwin took this close up of a power measuring glass holder used by eye doctors. "I became familiar with power measuring glass holders as my sight started to fail. With time, more and more thick glasses were prescribed by the doctor," he says.

Vaibhav Girkar took this picture of two visitors viewing the mural of a face at an art gallery in Mumbai. "I was not allowed to touch this mural, so instead of touching, I took this picture to share with others," he says.

Mahesh Umrannia took this picture on a summer afternoon in Mumbai in 2006. "I could manage to touch the lower branches of the tree and feel the warmth of the summer sun over my head. By feeling the difference of temperature and imagining the design of the shadow on the footpath, I took this picture," Mahesh says.
