For the majority of my weddings, I am the only photographer, making sure to keep it as intimate as possible, since more people are involved, it is less of an intimate wedding and rather a movie stage production. But for more than 150–200 people, I recommend a second shooter making sure photos of all the guests are captured including different angles. It is really hard to find a photographer that has a similar style to mine, but there could be potentially 2 photographers that could be available. For luxury, high-investment weddings I definitely recommend hiring a second professional photographer next to me and, in this case, please let me know, as I would like to discuss it with the person beforehand.
