John Singer Sargent

'Impressionism' was the name given to a certain form of observation when Monet, not content with using his eyes to see what things were or what they looked like as everybody had done before him, turned his attention to noting what took place on his own retina (as an oculist would test his own vision).

The habit of breaking up one's colour to make it brilliant dates from further back than Impressionism - Couture advocates it in a little book called 'Causeries d'Atelier' written about 1860 - it is part of the technique of Impressionism but used for quite a different reason.

I found myself at dusk in the bewitching Roman city of Jerash with H.M. Queen Rania of Jordan one year, and scrambling with hardened paparazzi to get an image of the Princess of Wales in a tiny Nepalese clinic in the foothills of the Himalayas another.
