Second shooters are photographers who assist the primary photographer during a wedding. They are often hired to help capture additional angles and moments during the ceremony and reception, and to provide a backup in case something goes wrong.

There are a few reasons why you might want to consider hiring a second shooter for your wedding:

1. More coverage: Having a second shooter allows you to capture more of the events and moments of your wedding day. The second shooter can focus on candid shots of the reception and other events while the primary photographer is focused on the ceremony and formal portraits.
2. Different perspectives: A second shooter can offer a different perspective and style, which can add variety to your wedding photos.
3. Backup: Having a second shooter serves as a backup in case something unexpected happens, such as a camera malfunction or illness. This can help ensure that you have a complete record of your wedding day.
4. More time: With a second shooter, you can get more photos in less time. This can be especially helpful if you have a tight timeline for taking photos or if you want to spend more time enjoying your reception.

Ultimately, whether or not you need a second shooter for your wedding will depend on your specific needs and budget. If you have a larger wedding or if you want to be sure to capture all of the events and moments of your day, hiring a second shooter might be a good idea. However, if you have a smaller wedding or a more relaxed timeline, one photographer might be sufficient.
