I go walking and take the camera. If the light is interesting I can find shots that would make a possible painting.
The camera records the structure and light and the painting plays with the colours.
The camera is a note book, the paintings can be very different.
It is all a game.
I paint still lives so I can have a much closer look at the light on things.
I have been a self employed photographer for many years working for the National Trust, English Heritage, architects, TV and all sorts. So the camera is a natural tool
