Now in his 70's, critically acclaimed artist David Hockney has taken a new turn in his glittering career as a painter and all round art ambassador.

Hockney has began creating art using his Apple iPhone, a device he only discovered a few months ago. Reluctant to call it digital art, the artist even has a miniature easel to sit his iPhone on in his London studio.

Never a technophobe, previously Hockney has worked with computers, consumer cameras, fax machines, Quantel Paintbox and Photoshop, playfully experimenting with technology, exploring both the strengths and limitations each offer.

Now the Bradford born artist sees the iPhone as offering a new challenge, creating work on a small canvas that requires you to think about composition, texture and colour. It also offers the possibility to share artwork, work in progress and ideas instantaneously with anyone in the world.

"This is all new territory for art. Sometimes I lie in bed and send illustrated art lectures to friends and also my own iPhone paintings. No camera is involved," Hockney told The Evening Standard. "I like to draw flowers by hand on the iPhone and send them out to friends so they get fresh flowers. And my flowers last! They never die!"

As someone who has embraced, and occasionally abandoned, many working methods Hockney's love for the iPhone doesn't seem like it will end in tears any time soon. "BlackBerries are for secretaries and clerical workers while the iPhone is used by artistic people."

A new David Hockney exhibition, 'Drawings In A Printing Machine', opened this week at the Annely Juda gallery, along Dering Street, just off New Bond Street, London. The show features work created on the iPhone and computer including photo manipulation.

"Whoever would have thought that the telephone would bring back drawing?" adds Hockney who recommends stroking the iPhone screen "very softly" to achieve the best results. "I happen to like the way that an iPhone has a sense of the absurd about it and is therefore close to life."
