We are having a small-ish (less than 100 guests) 50th anniversary party for my parents. I am not, nor do I plan to be a professional photographer, however, I have what I think is a pretty good camera kit and want to take decent pictures of the affair. It will be in a senior center hall so I'm not real sure of the lighting at this time. Any advice for settings and lenses to use? Thanks so much for your help.
