Color stripes appear on photos due to the following factors:
1. Digital screens have a refresh rate that does not synchronize with the camera’s shutter speed. This will cause color bands or stripes due to the different timing of the screen’s refresh cycles and the camera’s exposure;
2. Cameras with rolling shutters capture images line by line rather than all at once. When photographing a digital screen, which updates rapidly, this effect can lead to visible stripes or color distortions;
3. Some screens flicker at frequencies that are not visible to the human eye but can be captured by the camera. This flicker can result in color bands or stripes in the photo.
To minimize this issue, try adjusting Anti banding in the camera settings, or use a different angle or distance when photographing the screen.
