What are the examples of impressionist photography?

For example, Robert, the core figure of French painting photography? Demachy's work "On the Lawn" adopts the method of soft-focus photography, which shows the dim sunshine and the flicker of the picture, so that the girl in white lying on the grass adds poetry to the picture. The whole picture truly reflects the painting of the world of light with a brush of light. Is the crowd Robert? Another work by Demachy is full of pictures of characters, just like a microcosm of society, with various lives and bustling streets, which reflects the concern of19th century art for human nature.
