The stallions I worked with on this shoot in Devon are magnificent. Front on and in full flight, they are full of muscle and yet at the same time exude elegance. I can’t think of another animal that manages this balance so well. Little wonder their aesthetics have been the focus of artists for centuries. James Watt – the Scot who invented steam engines in the late 18 century – figured out a mathematical way to equate horses to engine power. Thus the term horsepower was invented. Looking at this image, I understand why he chose a horse.
