When Japanese scientists invented the self-timer function on cameras in 1978, they never could have imagined just how popular it would be 30 years later.
Currently, millions of young Chinese use the feature to take photos of themselves and post them online for the world to see. Websites such as Tianya and Tudou offer channels specifically set apart for self-portraits. However, according to experts, these sites offer more than just pretty faces. They also reflect a budding era of narcissism in modern society. "We all want to exhibit our true and best side to others, to attain praise, acceptance and recognition." Said a psychology therapist (治疗学家) surnamed Zhu in Beijing.
This is why, explained Zhu, some young people will post pictures of themselves alongside comments like "Am I a beautiful girl" or "If you think I am beautiful, give me support". "We are curious about how others look at us," Zhu said. The root of all this is narcissism, the love of the self. "Social psychology teaches that everyone is a narcissist, to varying degrees," Zhu said.
In recent years, this self-love has been helped by advances in technology, said Ye Lideng, a technical engineer at Canon’s Guangzhou branch. The era of cheap digital cameras, cell phone cameras and the availability of the Internet has driven the popularity of the self-portrait. "The availability of free places for photo-sharing encourages young people to take photos of themselves," said Ye. From social-networking sites like Facebook to self-portrait channels, today’s young people are being asked to show their faces.
To some degree, everyone posts their photo in the hope of getting noticed. "I am an ordinary girl. I am introverted and not beautiful, so I do not have many friends. But I still want more chances to communicate with others." said a freshman at Tianjing Technology University.
After posting some pictures of herself on the forum, the 19-year-old said she began to feel less anonymous: "Someone said I am very cute, and some said that I have a stylish dress sense. I was so happy."
However, self-portraits posted online don’t always reflect the real person’s physical flaws. Some people are so concerned about looking good that they use photo editing programs like Photoshop to erase the bad bits.
"People want to look beautiful," said a consultant at the Beijing Psychology Consulting Center. "Images showing good-looking people will attract more attention and give the self-portrait subjects great gratification."
For the most part, young Chinese seem not to be bothered by the fact that some self-portraits may be "doctored". "If you’re just posting the photos to share with others, I don’t think it matters if you use software to make them look better," said Bai, a senior at Guangzhou Ocean University. "I don’t feel like I’m being cheated, because the Internet is a virtual world. But if you use the photo to make friends, that is certainly cheating.\
