Painter / Digitally Abstracted Photographs
David Hockney uses the lines and dabs of colour from his later oil paintings in his iPad paintings. Similarly I use scribble and loose strokes of intermixed colour in my iPad paintings that originated from my conventional work.
Whilst great care has been taken to try and realistically represent the artwork's colour hue,
contrast, etc. it is impossible to accurately reflect the physical work of art using a computer monitor / screen.
