Mr.Yang Xiaoning particularly loves eco-photography. For years, he has systematically filmed the propagation and growing process of egret, the lively paddle of mandarin duck, the migratory hardships of swan, and moments of life of many wild birds. He once published two photography albums respectively called Egret Singing and Crane Dancing and Swan Song. The 50 multiple and slow shutter images on display were filmed with multiple exposure and slow shutter techniques, which are seemingly unreal and virtual but lithe and graceful, and have abstract ethereal feelings for readers to imagine. Mr. Yang Xiaoning expresses them with humanity and gives them profound humanistic spirit as possible as he can in creation. Among repetitive foldover and fascinating shadow, people can realize the fresh and forthright, harmonious family emotions of egret; taste the calm and leisurely, grace and lively posture of mandarin duck; and feel the elegant and skyward bearing of swan. And then, it will evoke people’s spirituous consciousness for caring about ecology and the earth.
