Many different artistic styles found landscape painting to be a fascinating subject. Impressionists used this form of painting because recording the way that light interacted with the world around them was the best way to hone their craft. Claude Monet, in particular, found depicting landscapes through this style a fascinating process, as seen in many of his works like 'Water Lilies' and 'San Giorgio Maggiore At Dusk'.
Although it's a rare occurrence, sometimes human beings are incorporated into these artworks. However, the depiction of people in landscape art is meant to enhance the beauty of nature as an additional element in the painting, rather than being treated as the primary subject. One example of this is in Vitali's work 'Seaside Summer I' where a beach scene includes a girl with a basket. Rather than detracting from the natural scenery of the piece, the girl seems to be at one with the surf rolling in and is depicted in a similar way so that her impact on the scene emphasizes the natural world.
The subjects available in landscape painting are diverse and cover nearly every mood and environs that the Earth has to offer. Images of forests, streams, ponds, fields, mountains, deserts, and even cityscapes or skylines are available through this art category.
