When you've been framed

The World's Most Photographed? Surely Princess Diana was more photographed than Queen Victoria; Michael Jackson more than Elvis? This intriguing show's odd title will be a magnet for summer visitors.

Part of the fun is working out what has been contrived for the lens, and image creation and manipulation is the linking theme of 10 subjects sharing a relationship with the camera. For Hitler and Gandhi, it was a political tool, for James Dean, a necessary evil.

The exhibition's time-span illustrates how portrait photography became a vital means of expressing status (Queen Victoria), politics (Mahatma Gandhi, Hitler, JFK) and glamour (Monroe, Hepburn, Dean, Elvis, Garbo).

Most intriguing are the photographs of Queen Victoria, who was born in the pre-photographic era, but rapidly understood how photographs could usefully please her subjects.

We see her glum face and widow's weeds, then she starts exploring - and even smiling. Should she be seen as soft and cuddly, with dog, or regal and remote, without? She tries both.

Mahatma Gandhi used documentary portraits to promote his Indian independence movement.

The classic photograph of him cross-legged in a peasant's robe, next to a spinning wheel, was an early, and successful publicity shot.

Hitler narcissistically manipulated his image, personally rejecting an elegant portrait in white tie, while promoting himself in dramatic public-speaking mode.

Post-War, the entertainment industry fed celebrities into the expanding film and music audiences via the new PR machine.

Garbo played sensually, to the camera at work, but is seen dazed by a shameless stalker's lens when old.

Even JFK played the game: the informal family pictures reminded America that a young, family man was in charge.
