In Guangzhou in December, Yu Kewei held a concert to bring visual and sound enjoyment to the fans.
With the dazzling lasers and lighting effects intertwined, an enthusiastic fan is fully engaged in capturing the best moments of his idol.
As the rhythm of the music changes, 10,000 lights and shadows dance in the venue, adding artistic colors to this feast.
At this moment, a dazzling green light suddenly pierced through the camera, instantly mapping the scene around the stage into a strange afterimage.
Fans were surprised to find that the phone lens was no longer clear, and purple dots were all over the screen.
He realized that his device had been tricked, and the laser had invaded the camera system directly, damaging the image sensor.
The staff who rushed to the scene after hearing the news apologized, but pointed out that the audience had been reminded to pay attention to the safety of their personal devices several times before the performance.
The performer shall not be liable for any compensation.
The incident unveiled the discussion of the safety of laser effects, and the audience's attitudes were polarized. Some people think that the performers have a great responsibility, while others point out that the audience should be careful in their own operations. In the same show, another fan was also troubled. When trying to zoom in on the lens, the sharpness of the image is severely reduced, and purple streaks are densely covered. Many people have questioned whether this is related to lasers. Questions were raised on Weibo, hoping for better preventive measures. It turns out that under the dual temptation of vision and experience, the laser effect brings hidden risks to the audience. With the development of technology, stage performance has been continuously improved, but related safety has also been taken seriously. Industry insiders suggest that in addition to emphasizing personal responsibility, performers should regularly inspect equipment and repair possible hidden dangers in a timely manner to provide a safer and more enjoyable interactive experience for the audience.
With the popularization of network technology, live broadcast and on-site sharing have become the new highlights of the concert. Many fans will take out their phones and want to use their cameras to record the moment when their idol shines. But recently, fans have been complaining that in some big concerts, their phones are under laser illumination, and the shutter speed for a long time will quickly produce purple streaks. In fact, there is a difference between the camera and the human eye in dealing with bright light. Cameras' sensors work in bright light and capture a wider range of light, but they don't have the ability to adapt to the human eye. The human eye, through pupil adjustment, can adapt to a variety of light, while the camera is not so lucky.
Under strong light effects, the camera's image sensor is easily damaged, and this damage is difficult to repair. In fact, with the improvement of shooting results, the camera parameters of today's mobile phones are getting higher and higher, with larger aperture and higher light sensitivity, which creates conditions for shooting in strong light environments, but also makes mobile phones more susceptible to light hazards. Some fans caught the video and found that purple streaks appeared as the magnification increased, indicating that the phone could open the shutter for a long time under strong light and cause damage to the charge-coupled device or complementary metal-oxide-semiconductor sensor. In this regard, some performers will take certain measures. For example, the lighting and laser equipment of the venue are used to irradiate the position of the mobile phone camera at a certain intensity, which can not only create a visual effect, but also play a certain role in blocking the mobile phone from being too easy to shoot the whole performance.
Although this practice will bring certain hidden dangers to some fan equipment, it is also necessary to protect the rights and integrity of artists' performances. In this regard, fans need to improve their safety awareness and not easily turn on the mobile phone camera for a long time surrounded by strong light to avoid damage to the device. At the same time, on-site staff should use the lowest light intensity to create visual highlights and minimize the harm to the phone. At the same time, some high-end phones are constantly optimizing the camera hardware to improve the light resistance. Some phones may adopt a variable aperture in the future, which automatically adjusts the ISO to adapt to different lighting environments to protect the sensor and user experience. Only by working together can the audience enjoy the show as much as possible while protecting their equipment.
