Article: Snapshots, the new fashion for an artistic portrait photo: Take it underwater. Zhang Xiaomei, a 20 something Shanghai native who works in the media industry, tried it out twice. "It was a completely different experience," says Zhang of her first such experience last May. "You get the feeling that you're cut off from the rest of the world. But also it s romantic and like a fairy tale." She then successfully convinced her husband to be to have their wedding photos taken underwater a couple of months after her first try. "Can you imagine a 1.87-meter-tall man trying out something like a fishtail under the water?" Zhang says, laughing. A commercial underwater photo portrait is perfect for post 80 and post 90 generations who adore taking snapshots, but are looking for new ways to be artistic, says Ai Cheng, owner and photographer of No.55 Underwater Photography in Shanghai. Ai opened a studio in Shanghai's suburb of Songjiang two years ago, building a 5-meter- deep, fan-shaped pool equipped with heating facilities to start up the business. A 30-minute training on how to smile under the water so that you won't drink too much water and how to open your eyes underwater is offered in his studio for those who don't know how to swim. Ai says most of his customers are female--half of them coming for an artistic portrait photo and the rest for wedding pictures. "Some of them drag their boyfriends or husband-to-be, who are unwilling to go down to the water, to shoot as well," he says.

"Go away, you silly bird, ''the man said to the penguin, but the bird ignored him. It simply would not leave him alone.Wherever he went, the bird went too. At last, in desperation the man walked into a police station."Excuse me, officer." he said. "I need some advice. I met this penguin in the street and I don't know what to do with it." A bored policeman looked up from what he was writing and said, "Just take it to the zoo, sir.'' "Oh,all right.''said the man. The next day the man was walking along the street, still accompanied by the penguin, when he met the policeman he'd spoken to the day before.The policeman was not pleased to see them."I thought I advised you to take that animal to the zoo, " he said. "Well, yes, officer, you did.And I did take him to the zoo, " the man explained. "And we had a great time. But we can't go to the zoo every day.I thought today I'd take him to the movies.''
