Are the samples taken by the studio themselves reliable?

The essential difference between "sample film" and "guest film" lies in the expressive force of the bride and groom in front of the camera. Like some professional model actors, their expressiveness in front of the camera is very good, and they often keep a relaxed and natural smile on their faces after making some very laborious movements, which is the embodiment of their expressiveness. What ordinary guests need to do is to practice smiling more at ordinary times, form a tacit understanding together at ordinary times, and keep full of energy, happy mood and true feelings when taking pictures.
