I wouldn't put myself in a position where I would be a main photographer for an event. It's just too...stressful no? However, to do one at the side? Be the "extra" photographer capturing other moments along the way, that I can do.
So when D&D asked me to help with their wedding photography, and that they had already hired a professional as well, I feel less stressed to help them out.
The professional photographer's job was to capture the events at the wedding itself, while I had the joy of shooting the candid moments along the way.
Quite glad to have done so, really happy with some of the results (not all), I hope the couple like the photos too. =)
