They have contributed the pictures, taken on their mobile phones, for an exhibition opening this week.

The exhibition also features photos from artist Jack Vettriano and Sir Peter Blake.

The photos will be auctioned in aid of Mencap after the exhibition, which begins in London at the Association of Photographers' gallery on Wednesday.

The mobile phone art has been dubbed Fonetography by Nokia, the exhibition's sponsor.

The gallery said the brief for each of the artists involved was "simply to capture the moment".

Organisers said they wanted to see what some of the leading visual artists could do with camera phones, which have had an impact on everyday photography.
