Why don't you wear white t-shirt anymore? is the photo book by Tung-Lin Tsai (蔡東霖). The book contains a series of cyanotype photographs printed on Tung's handmade Kozo paper. The photographs are first printed on Washi paper with cyanotype process, and later transformed into Riso prints as book pages. Cyanotype is an old photographic process. Through this process the pictures translate into blue and white. In Why don't you wear white t-shirt anymore? The original images of everyday life are portrayed with the lightness of cyanotype and Washi paper. Under the weightless paper and monochromatic pictures is longing and repetition. For Tung, photography is an endless letter and has to be written with one singular color. "Why don't you wear white t-shirt anymore?" is not only a letter to someone, but also a letter to photography.
