Yes of course.  These are very important, I'm very good at organising & getting through them. But it does help to ask bridesmaids and groomsmen for a little help rounding everyone up.  It's easier on you both, & if you limit numbers to immediate family.  There are less delays waiting on people.  Letting everyone know in advance when and where the family photo's are taking place can also make this easier for you both & everyone else.
