Is photography only for the sighted? A group of seven visually-impaired photographers beg to differ, with an exhibition of their works that employ sensory photography - photography that employs senses other than just sight to create images. We speak to Vivien Kwek and Svivabalan Selvarajan, two of the photographers on show, and Ken Goh, one of the organisers, about sensory photography and how it can be a way of empowering the visually-impaired community.
