What props are used for white photography?

The most important thing about this is that the white balance setting is incorrect, resulting in blue. Please customize the white balance for the empty frame first. Please refer to the camera manual for how to operate it. Each brand is slightly different, so I won't elaborate.

After the customization is successful, the camera will prompt you to set it to white balance to get white. If there is insufficient exposure or light, it will still be gray, but it will not be cast.

If there is still deviation, please correct the color cast of the display first.
