From Atkins, Sight for All and Zeiss:
This photographic challenge has been designed to bring focus onto a gift that photographers often take for granted, their eye sight. Photographers have fantastically tuned vision, coupled with a strong sense of design. This challenge, which is to be completed in one day, will both raise funds for Sight For All and produce an exhibtion of pictures that tells a striking story.
