Colour and texture are important, as is abstraction – the imagination reads abstract images as personal, new. Natural forms are often abstract – landscapes, leaves, water. My favourite reaction to my images is 'What is it?'. I used to go into detail, now I want to hear their answer. And people.. they don't want their photo taken, but if you ask you lose what you first saw. Rob Walsh lives in Riddlesden, near Keighley.
