The weir next to Pulteney Bridge in the centre of Bath. I used grey ink for the initial drawing, the same ink diluted in a water-brush for the tone, and then watercolour over that. There’s a great interview with Steven Reddy (link below) explaining how he uses this technique. He describes it as “black and white does the work, colour gets the credit”.
