Apart from just being so beautiful, so full of attention to nature and the world around us, his work also explored how photography can’t capture or communicate the seeing and feeling with two eyes. To that end, he embraced photography, attempted to express movement and volume using photo camera(s), his polaroid works are beautiful, and then he came back to painting. He wrote and spoke about his process and "seeing" the world a lot, I really recommend it if you are into visual arts.

His work with photography influenced my thinking in the 1980s. The ideas of viewing time and moving focus I think are significant in human experience.

He talks about it, and you can see some of these works in a YT vid here:
