I'm a great admirer of Darren Woodhead's interpretations of the natural world. He works from direct observation outdoors and uses watercolour in a free expressive way to record his subjects.
I've never seen Darren's paintings displayed gallery wall so I'm afraid my enthusiasm has been generated from his book 'Up River: A Song of the Esk' and the paintings displayed on his website at:
I find Darren's kind of painting much more interesting than the more studied realist work done in the studio. You have to admire the effort that some artists put in to achieve photographic detail - and maybe that is what many collectors look for. Personally I fear that painterly qualities are often lost in photo realist paintings. When you look at the work of artists like David Sheppard for instance you quickly become aware of his brush work which confirms that you're looking at a painting not a photograph.
