光的操作

光的操作 (2013)

at ONE, Shanghai, 2013.

I used two light sources for this work. One of them is a strobe light to flash quicker than usual. This strobe light is in a diffuser and repeatedly switched on and off faster than the human eye can detect. This results in the light appearing to be constantly on but the balance of the time the light is on and off is controlled in different cycles.

The other one is a video projector. This is called DLP (Digital Light Processing) and it looks like just a white light projected but actually sometimes red light is projected and at other times other single colour like green or blue light is projected. By projecting all the single colours at the same spot, the human eye recognises them as a combined colour. If they are not projected at the same spot, a different colour will be seen.

Because One is located next to the IMG SRC Shanghai studio, I could use all their specialist equipment and so the project benefitted as a result.
I hope you enjoy and discover many things in my work.

本作品同时使用两道光源。
其一是超高速闪烁设置的频闪灯。它被安装在漫射光照明装置中,以肉眼无法识别的速度循环开启与关闭的过程。这道看似恒定亮度的白光,其实是按照一定比例进行开关,以不同周期进行明灭操作的。而另一道光源则是来自视频投影机。采用的是被称为DLP的方式,虽然看起来只是普通的白色投影,其实是以瞬间红色,瞬间绿色,瞬间蓝色这样的顺序进行着投影。由于它们都是被定点投射到同一位置,所以人类只能感知到三色的混色。只有当它们被分别投射到不同的位置时,我们的肉眼才能够分辨出不同的颜色。
作为展示会场的ONE空间与广告设计公司上海壹美索的办公室相邻,摄影器材,放映机,电脑等各类设备都很齐全,所以我也顺其自然地利用这些器械进行了创作。
相信大家可以通过观察发现作品的更多乐趣。
