Gerhard Richter exhibition in the heavy snow

I went Gehard Richter exhibition at kawamura musium in Chiba. One of his representative painting method is to redraw on photoes. They were like photoes at the same time like paintings. I was interested in some mirrors and glass boards in the exhibition. The mirror was just a mirror, and glass board was just a glass board. My figure was reflected in the mirror or glass board. Did he want to express the figure reflected in the mirror or glass board? That is those who sees his work. It was interesting. In the separate issue, but it was heavy snow today. A lot of visitors had come to the exhibition in spite of the heavy snow.
