The artist uses a unique technique for these series, where he creates by rendering a photograph of the sky or the nature with an ink-jet printer on a wood surface and later applying acrylic paint and aqueous varnish. Finally sanding the dried surface, eliminating thick layers from the paint and varnish. Due to the smoothness of the surface and the image, the paintings simply look like a photograph capturing a beautiful moment of the ever-changing expression, as pointed out by renowned curator Ayako Miyajima.

The concept of memory is a persistent theme in Azumatei’s work. This also explains why his works are composed of two layers: the “objective” photograph on the bottom layer that corresponds to the record, and the “subjective” multiple layers of paint and varnish that are applied over it, which are equivalent to the memory.
