What causes this effect? What am I seeing?
berkeman said:Or possibly the refresh pattern. Can you post the picture that you are asking about, jreelawg?
The distorted grid effect in photos of LCD screens is caused by the interference of the camera's shutter speed and the refresh rate of the LCD screen. As the shutter speed captures a still image, it may capture the screen in the middle of a refresh cycle, resulting in a distorted image.
Yes, the distorted grid effect can be fixed by adjusting the shutter speed of the camera. A slower shutter speed can reduce the interference and result in a clearer image of the LCD screen. Alternatively, using a camera with a higher frame rate can also eliminate the distorted grid effect.
Yes, the type of LCD screen can affect the distorted grid effect. Older LCD screens with lower refresh rates are more likely to produce a distorted grid effect in photos compared to newer LCD screens with higher refresh rates.
No, the distorted grid effect is not harmful to the LCD screen. It is simply a visual effect caused by the interference of the camera and screen refresh rate. It does not affect the functionality or longevity of the LCD screen.
Yes, the distorted grid effect can be prevented by using a camera with a higher frame rate or adjusting the shutter speed. It can also be avoided by taking the photo at a different angle or distance from the LCD screen.
