研究發現，水干技法原本適合的大面積潑灑。居然可以在小面積中表現其特色，於是本作品水干技法出現在岩石部分以及海浪打底上，在藍色水干上加上白色浪濤。

The research found that the water-drying technique was originally suitable for splashing color in a large-scale painting. However, I found that its feature can be expressed in a small-scale painting as well. Thus, the water-drying technique appeared in depicting rocks and painting base color of waves in this creation. For example, adding white waves to blue water-drying pigment.

発見：水干の技法は元来、大きな面に撒き散らすのに良いが、小さな面でもその特色を表現できる。そこで、この作品では、水干の技法を岩石の部分と波のバックに用いた。藍色の水干に白い波を加えた。
