Slight water damage to my camera?

I have a nikon d3100 and I was out shooting pictures of waves (my camera isn't waterproof) and an unexpected wave came up and splashed my camera. I took it out and dried it off thinking it wasn't that bad. Later there was fog under the screen and when I took a picture it was overexposed (I'm positive I had my exposure correct) I had the sb400 flash and kit lens attached. I removed the battery, sd card, lens and flash until I got home then placed it in rice. Should I take it to a camera repair place for inspection or do you think it will be fine?

There's no SLIGHT water damage.

Either it's wet or it's not. If it's wet, it's dead.

I'm afraid your camera is dead. It got wet while it was powered up and then you tried to use it. Water and electronics don't play well together. Chances are your flash is also ruined, as is the kit lens. You can send the camera, lens and flash to an Authorized Nikon Repair Center (there should be a list in the back of your Owner's Manual) for an estimate but don't be surprised/upset when you're told: a) all three pieces are unrepairable or b) the costs of repair will exceed the costs of buying all new equipment.

In the future you might want to consider a protective cover like the ones found here:

The camera is probably a goner.

Putting a camera in rice is not always the best thing to do. Your camera has a mechanical shutter, and rice may remove the lubricating oils from the shutter. At the very least, rice dust will surely get inside of the sensor cavity.

You can send it to a camera repair place, but if there was water intrusion - made worse by rice dust, they will probably just pack it up and return it to you.

Especially with salt water, if you even get the water out, the salt and other minerals that remain will severely corrode all of the exposed electronics.
