Of course – you should definitely have some.
Traditional Wedding group photos are still really important and valuable additions to you collection, it may be the only opportunity you’ll ever get to all have of your favourite people together at the same time.
I typically set aside for these to around 20 minutes. Years of experience has taught me this is optimum to stop the guests getting bored and distracted but still ample time to ensure we capture all the most important friends and family portraits.
Before your wedding I’ll send out my planning document and ask that somebody in the wedding party is nominated to gather people together and help run things as smoothly and efficiently as possible. Doing this allows for the most photos in the minimum amount of time. I always do and “whole group” shots first.
