If it is fully recorded, there will be at least 3 photographers for ordinary meetings and at least 5 photographers for large-scale annual meetings.

Two cameras are usually enough.

Where to find someone? It is cheapest to know the photographer directly, followed by the studio. Weddings are outsourced (temporary looking for someone), and advertising companies are also outsourced, with the highest price, which is generally at least three times that of directly looking for a photographer. I am a photographer myself. At the end of the year, advertising companies and their annual meetings have a lot of work. We are willing to take the job of an advertising company, because there is more money and we don't have to worry about anything. When we start working, we will get paid. It's more worry-free than finding a job yourself.
