Glaze
(2017 – ) Gelatin Silver Photogram
When I relocated back to Japan in 2014, I started to re-experience the gradual change of the seasons, and observe the surrounding ordinal nature more carefully. It also provided me with opportunities to see traditional events and crafts and in particular, I became fascinated by the techniques and materials used in arts and crafts that spring from a close relationship with the natural environment, such as natural dyes, pigments and natural glazes. Inspired by those techniques, I have attempted to apply these elements to photography, and this series came about as a result of my experiments.
In this series, I capture natural processes, such as falling rain, melting snow and ice, or changes in the moisture content of soil, directly on photographic paper, exposing it under the sun, then using a chemical process to ripen it.
Black and white photographic paper is normally monochromatic, but through exposure to daylight, it gradually changes color. Leaving it outside for anything from a few hours to months, the paper shifts to blue, pink, or purple. These differences of color are created by temperature, humidity, chemical substances in an object, and the amount of ultraviolet light. The raw images take on rustic colors; reddish brown, brown, or khaki, through a process employing specially prepared chemicals. Some of the latent silver can be brought out, adding to the complexity of the images. This phenomenon occurs due to changes in the size of the silver particles. Different sized silver particles scatter light in different ways to produce the different colors. I feel this process is very much like making ceramic glazes.
