As a first step, the contrast between the sky and the lake can be clearly seen starting from the horizon. Today it was cloudy, so there was little movement of light with time. And the second step. The surface of the lake is very dark, and the sky is also getting darker. And the third stage (roughly divided). The more closely I looked, the more the surface of the lake reached the brightness of the sky, and then it spread to the horizon. I’ve experienced this kind of perception phenomenon many times before. The question for me is how to paint from here. And I knew that the answer could only be reproduced in oil, but I spent some time in an indescribable space, in an indescribable sensation.
