Standing in front of 10 blind children in a small

　　lecture­room, Cai Cong instructs them step­by­step how

　　 to take a photo without seeing an object.

　　 "Let's start by locating (把......设置在 ) ourselves in

　　 the environment and sensing the frame of our image，" Cai,

　　who is also blind, says.

　　"Stretch (伸长) your arms to touch what's in front of you,

　　on your right and on your left"．

　　"Then let senses guide you to discover the subject you want

　　to shoot, and visualize (想象) how they will look in your photos."

　　 Finally, Cai places the camera to his forehead, takes a

　　 breath and presses the shutter.

　　The kids pair up with volunteers without sight impairments

　　 (损害) to practice discovering images and shooting photos

　　 by sound, touch and smell.

　　The training of non­visual photography is part of Cai's work at

　　One Plus One Disabled Person's Cultural Development

　　Center based in Beijing. Non­visual photography is just one of

　　its many projects.

　　 "We never expect our students to take pictures that look

　　exactly the same as those taken by sighted people，"

　　Cai explains. "It is about expressing, sharing and breaking the

　　stereotype (固定形式) of the blind in society."

　　"The public usually thinks blind people can't do photography,

　　but it's not true. For us, grass is more than green - it smells fresh and feels lush."
