To see is to believe. Two complementary coloured lights add on to each other and cancel out each other whereas the shadow captures that process. Working with the limitation of optics and illusion, I encourage the spectator to think about what it is that they see.
I transform the optical phenomenon of the negative afterimage and its psychological version, ‘after-sensation’, into a five-minute moving image. I staged two complementary-coloured artificial light source in symmetry, displaying the colour yellow and blue respectively. In the RGB colour system, mixing the primary colour blue with the complementary colour yellow would produce the colour white. The yellow light switches off all of a sudden, leaving a sea of blue light. Then the blue light is gone, only darkness remains.


互補色的光重疊。它們互相抵銷,影子卻留住了顏色。
眼見為實? 視覺主導了我們對世界的感知。這份作品源於我對感官與感知的邊界的探究,觸及光學和幻象視覺的限制,試圖令觀者思考自己的所見。
我將「負後像」(after image) 這個視覺生理現像,以及心理學家稱之為「後感覺」的、停留於視覺的殘影,轉化成五分鐘的流動影像。影像中的我設置兩個互補色的光源,對稱地打在白幕上。互補色光源加疊後,原本的投射在白幕上的顏色會互相抵消,呈現白色。黃光消失於一瞬,餘下一片藍光。然後,藍光也熄滅了,畫面頃刻剩下黑暗。

Biography
創作者簡介

The primary interest of Echo Hui (HUI Gi-wai, b.1996) is to explore the senses, especially vision. She investigates the boundaries of the senses and perception while crossing disciplinary lines into the realms of science. She often works with light, chemicals, images and moving images, how audiences' motion and perception affect a work and vice versa. Echo’s focus on sight-related mediums is her way to challenge how we see reality.

許芷瑋,1996生,作品關注感官,尤其對視覺如何主導人類感知現實最感興趣。許探討感官與感知的邊界,近作利用光學和幻象探討視覺的限制,在藝術與科學之間遊走。作品形式多以光、化學品、影像、動態影像為主,觀者的感知及動態與作品裝置互相影響。許期望透過視覺主導的創作媒介去引起非常態的視覺感官討論,向我們所見的現實提出質疑。
