Usually, after the director finished shooting a onset, the onset personnel held the ball and card, added CG elements to ensure the same camera with the same Angle and environmental lighting, and then shot the same material for later use. In post production, it was only necessary to find this material for reference and matching.
It is necessary to communicate with the crew in advance to use the actual camera to shoot the material. If you use your own SLR to shoot the material, the color space and white balance of the reference material do not match the actual material, so it will be meaningless.
All shots with CG elements need to shoot the ball color card material. Every time there is a change in camera Angle or ambient lighting, we need to shoot a new material.
If the CG element is moving, the crew also needs to move it with the differential ball card.
