If you dropped your digital camera into fresh water, you might have half a chance: Turn off the camera immediately, remove the battery, put it in a dry place, and leave it alone for a few days to air out. If the camera works after that, consider yourself cosmically lucky. There’s an urban legend that contends that if you drop a camera in salt water, you can flush it by plunging it in fresh. The folks at Essex Camera Repair in Carlstadt, NJ, say that’s bunk. But since they also say that salt water messes up your camera so badly that you shouldn’t even bother to fork over money for a repair estimate, we think it can’t hurt to give it a dunk.
