Before zooming your wedding, you need to determine what equipment you plan to use.
First consider your device, will you use a laptop with a front camera or a cell phone with a good camera? In either case, you should consider raising the device at a good angle using a tripod or table.
Using a tripod frees up one of your witnesses to be fully present in place of the amateur cameraman.
Consider using an external audio device. If you want to eliminate cables, look for a discreet Bluetooth microphone or headset. Pair it with your recording device for enhanced audio. Be sure to test this audio ahead of time while you still have time to find an alternative AND on the day of the event to account for noises at the location.
