Yoshio Machida was making collage work in 90s. He was using photopaper as one of materials from that time. It was used as a symbol of light. After several years, he extracted only this material and started to use it as main medium. He called this work "Photobatik". Photobatik is made without camera. But it's different from photogram (rayograph). In photogram work, exposured area and unexposured area basically exist at the same time. On the surface, exposured area becomes black and unexposured area becomes white. The image is formed as the result of the contrast between light and shade. But in Photobatik, there are no unexposured areas. All image in Photobatik is made in the process of exposure and development. This making process is the same as batik's one. Photogram expresses "partial exposure and whole development", but Photobatik expresses "whole exposure and partial development". Recently Machida advanced this technique more. Now he is making work without developer liquid. Photopaper is just overexposed and fiexed. As a result, it entirely looks light pink. In 2011, Machida produced video works using images from Photobatik works. For solo exhibition in Bulugaria in 2012, Machida exhibited several works using rope, wire, embroidery and sound and video installation with the theme "Maru" (means circle). "Scape*dance" (DVD 2011) is here.
