I have got an iPad, what a joy! Van Gogh would have loved it, and he could have written his letters on it as well.

People criticized me for my photography. They said it's not art.

And then I went round the corner and there's a Van Gogh portrait, and you just think, well, this is another level. A higher level, actually. I love the Sargent, but it's not the level of Van Gogh.

I was aware that the teaching of drawing was being stopped almost 30 years ago. And I always said, 'The teaching of drawing is the teaching of looking.' A lot of people don't look very hard.

Drawing takes time. A line has time in it

Water in swimming pools changes its look more than in any other form its colour can be man-made and its dancing rhythms reflect not only the sky but, because of its transparency, the depth of the water as well. If the water surface is almost still and there is a strong sun, then dancing lines with the colours of the spectrum appear everywhere.

The urge to draw must be quite deep within us, because children love to do it.
