Assuming your party is either in the evening or indoors, you’re going to want to set your camera to manual mode to take control of the exposure. In low light conditions, you basically have two options: widen your aperture to capture the most light, or use a flash.

I’ve been asking around about night time party photography, since I am more of a video guy but I have got a few parties lined up. So I have heard different things from different people, one of my friends who does quite a bit of night time party events told me to set my settings with a smaller aperture.
