Painting primarily large canvases in oil, she portrays the landscape as being both breathtaking, and yet hostile, though without narrative content. Inspired by the moor land animals, and their ability to survive the elements, Katharine paints freely to evoke movement and energy within her subjects, emphasising the light contrast, and ever changing moods of the moor.

Katharine has also recently produced a series of moody, dramatic seascapes of the North Cornish and South Devon coast.
