Slow Sync Flash

See if your camera allows for this mode. Many camera do, even less expensive models. You can do some impressive visual work with slow sync flash on your camera. See this website for some examples:

Slow Sync Flash

It can be really simple. Just make your shutter speed lower than normal (1/30 or so, around there, the opposite of the higher shutter speeds we use for freezing things like water droplets). Now add your flash. If you have a mode for slow sync flash, put your camera into that mode. Check your manual to see, or google it! Slow sync can be used for shots you wish to remain stable (no movement), or for shots you wish to pan. The Panning slow sync shots can create really interesting results.

A few examples from my own portfolio to share:
