Early in his 20 year painting career, Karl, who is entirely self taught, hit on a familiar monochromatic style of portraiture, which although characteristic and stylised, became a form of trademark for him.
During Karl’s life, his journeys led him to France, where amidst the vineyards, lavender fields and olive groves, his work was to change in it’s very nature, there using full light and colour he was to realise a need to present feelings in an expression of personal reaction to the experience.
In early 2011, he relocated to Snowdonia, aspiring to paint the area after spending several years walking there absorbing the mountains and, moreover, the remnants of its industrial past. He became the artist in residence for The National Trust's Ty Isaf in Beddgelert.
