This industry is in a mess now. Many people who are engaged in follow-up shooting only know some basic shooting skills, or copy other people's guest films online. If you are not a graduate majoring in photography, you can buy some books and browse other people's good works online. If you have no experience and work, it is very unlikely that a new person will come to you for follow-up. As for the master, unless it is your family, good friends, classmates and the like, no one will sincerely teach you your skills (as it is). Actually, you can take more pictures of people first. If there is a wedding of relatives and friends, you must not miss it. Bring more equipment and take more photos from morning to wedding. You can sum up a lot of experience by yourself.
Wedding photography, like news photography, only pays more attention to beauty. In fact, the requirements for photographers are very high. If you want to enter the industry, you must practice your basic skills. Watch more and shoot more, and you will succeed.
