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.

Everything does come from nature. That's where you get new ideas. Just draw the landscape. I felt doing it with a bit of burnt wood was also good because I was drawing burnt wood with a piece of wood. I wanted to do black and white. After using color, I thought black and white would be good. You can have color in black and white. There is color in them, actually.

Drawing is rather like playing chess: your mind races ahead of the moves that you eventually make.

I've no doubt that those photographs i took will make people look at everything in a more interesting way - the little tear on one piece of paper, the shadow on another. But good painting has always done that - made you see things. And the most ordinary can be the most extraordinary.
