It hover in the sueface forever. But in the contemporary photo , because of surface of pursue goes perfect, on the contrary matter center of moment, with self express photo action, exhibition manner seems very west, on the other , reflect material society of dole visual angle and make demotics of interpret

它永远在表面徘徊，但在当代摄影家手中，由于对表面的追求发挥到了极致，结果反而酿成了到达事务的核心内容的契机，他们进行着观念先导的艺术实践，不断的用"自我"来表达着摄影的行为，展示方式非常西化，但在其中又不断的折射着物质社会的一种"哀"视角，将摄影家的"我"通过他者的身份上升到一种大我的境地，进行着镜头的社会语言阐释。
