To create his intoxicating Rainbow Waves (2013), Taisuke Koyama submerged in the sea his earlier photographs from Rainbow Form (2009) then re-photographed them using a macro lens. The intervention of refracted light through the rippling water gives this familiar motif a new meaning. Rainbow Variations – Koyama’s ongoing exploration of photographic image-making and perception – is underpinned by his initial act of appropriating a rainbow-illustrated advertising poster on the ubiquitous beverage vending machines in Tokyo. Koyama was selected in 2009 for Foam Talent, Amsterdam, and his works are held in various collections, including the Jean Pigozzi Collection, Geneva.
