Plein Air painting and Alla Prima painting capture the essence of a scene, the attitude of a landscape, or the character of a moment. Most often completed in a single sitting, these works feature lively and impressionistic views, bold gestures, and impromptu mark-making.

Artwork in the show is available for purchase through this website or the Gallery, unless marked "not for sale" or "out of stock".

If you are out of town and need your purchased artwork shipped, prices do not include shipping or handling.

About Brooke

Brooke Borcherding took her easel outdoor for the first time in 2009 and has been producing a prolific output ever since. Over the past decade as an exhibiting artist Brooke has become nationally and internationally collected, exhibited in numerous galleries in the PNW and most recently has been featured in Sep 2022 issue of Plein Air Magazine for urban plein air painting. Her unique style evolved from a desire to investigate human perception in aesthetics, and to stimulate our human senses by exaggerating the color and space we see around us.
