What background wallpaper is yellow and suitable for photography?

Use ordinary PVC white background cloth. Whether it turns yellow depends on the color of light and the setting of camera white balance. It is recommended to use a photographic lamp with the same color temperature as sunlight when shooting, and the white balance of the camera is also set to daylight mode. It is best to shoot in raw format, and use ps, lr or Nikon after taking pictures. Canon's own software will adjust the white balance later.
