While you're shooting, don't focus only on the people. Catch the details as well, whether it's the food, the decorations, or the location. These images can add a lot of personality to the party photos and will honor the time spent preparing for the event. Snap a shot of table spreads, party favors, and anything else that gives a sense of what the party is celebrating. If you're at a graduation party, take a photo of the graduate's mortar board cap or diploma. If it's an engagement party, get a photo of the ring.
