Working in the traditional French Barbizon style, Sheehan captures pastoral scenes with close attention paid to mood and atmosphere. In this video Dennis uses the ‘reading in’ method of painting, where an artist starts a painting by making marks and seemingly random brushstrokes on the canvas, then embellishes what those marks and brushstrokes suggest, to produce a painting. This method uses very little in the way of reference material apart from what’s already in the artists head.
