Roughly 10 years ago she started to focus on plein air painting. Over the last five years Katerina has challenged her abilities by painting in the city (Karlovy Vary & Prague in the Czech Rep.; San Francisco & Angels Camp). She says about painting cities, "Everything-- except the architecture -- is in motion. Cars, trucks, the cable cars, and people. All this action forces the artist to develop a sort of stop-motion ability with an emphasis on one's peripheral vision to catch over one week the one scene that is depicted on the canvas. I paint two or three canvases over an entire week, also capturing into my brain through my eyes all the pure colors".
