Welcome to iPhoneForums, somf559!
Are you able to take pictures?
Try the usual fixes:
Force close the Camera app, restart your iPhone and reset it.
To force close, double tap the Home button to show the multitasking bar. Slide the thumbnail above the Camera app icon towards thentop of the screen.
To restart, turn off your device, wait for a few seconds and turn it on again.
To reset, press and hold Home and Power button at the same time until the Apple logo appears. Let go of both. The iPhone will power up on it's own. This kind of reset won't remove data or settings.
