I've done a few group photos in my time - wedding work does that for you.
My most memorable experience though was a group photograph of just about all the attendees at a retirement party for an experienced and very popular courtroom lawyer - a Queens Counsel and a former bencher at that.
The group included Justices of the Court of Appeal, Justices of the Supreme Court of BC, other Queens Counsel and all sorts of other counsel as well.
All people who love to control things!
And this was well into the event - and there was an open bar!
It took all of my courtroom advocacy skills to manage that crowd!
The results were satisfactory, but sadly I didn't keep those negatives so I can't share them here
