This experiment aims to make the hidden connection obvious. I investigate the real physical moment in urban context via photograph. I capture a cityscape from level 45 in Guangzhou, China, then use the cityscape photograph as investigating target. The objects are highlighted by abstracting the same colour (green /orange /blue), which aims to seek which elements are highlighted at the same time. Are they relevant to each other? Is there any hidden connection between one another? They might be located at different spots and be sorted in different categories such as building elements or nature.
