Is it necessary to have two cameras for wedding photography?

First of all, you can't ask this question like this. Is it up to the couple's own choice, not the recommendation of the wedding etiquette company? Two stations can use one host to shoot the whole process of new people, and the other is responsible for taking close-ups and parts, or cheering and blessing scenes of relatives and friends. The videos taken by these two seats can provide more and better materials for the post-editing teachers, and the final video can better show and retain the wedding day of the couple. If you don't care about all this, a camera position will do. Which local tyrants are married, there are many positions with rocker arms, just like the party scene. So, the number of seats is up to you two to discuss.

I am a wedding photographer, but we chose to travel and get married, and we didn't do the wedding ceremony, let alone the wedding photographer.

Best, I wish you both happiness!
