Wedding follow-up actually involves wedding photography and wedding video. Photography refers to taking still photos, and camera shooting refers to shooting dynamic videos. After China's reform and opening up, videos appeared in fashion weddings. At that time, videos were recorded and played on tape, and there was basically no post-production. With the popularity of computers and nonlinear editing, more and more wedding videos are being edited and produced later. One of them has to mention a big boy in his early twenties, named "Tang Chi", who resolutely sticks to the tradition and shoots weddings in his own unique way. Finally, in 2008, he filmed a wedding follow-up work "Seven Years", which completely subverted the traditional concept of wedding photography and became popular overnight on the Internet. Many people exclaim that wedding videos are actually the same as movies. As a result, almost all wedding follow-up photographers began to imitate Tang Chi, and the field of wedding follow-up photography began an unprecedented reshuffle. The cameraman who followed the wedding gradually became the director who followed the wedding.
