Buildings

Buildings can give a landscape painting a geometrical element or pattern, an opportunity to introduce colours and shapes not found in nature. 

The proportion of built to natural environment can be played with. These two landscape paintings have an almost even balance between buildings and nature, creating an interesting tension. 

The townscape or cityscape, is a subgenre of landscape painting that emerged in the seventeenth century.

The top image is a detail from a painting by the Danish artist Christen Kobke.

The lower work is unknown.

Noon Down Leavenworth, Oil on Panel, 10 x 13 inches, 2008

This work successfully captures the haze obscuring objects in the distance. Tonal contrasts are much greater in the foreground.

Not really landscape, but wonderful simplicity,

restrained palette, and graphic qualities that could be applied to landscape genre.
