My wife got a snapshot today of my grandson catching his first fish - a moment to remember. Unfortunately, she had just come from an air-conditioned house into the heat of midafternoon in Alabama, and the lens was apparently fogged. The image looks overexposed, but I'm sure it was just fog on the lens. My question is, can the image be saved in Photoshop? I know you can't create data where there is none, but what is the best way to maximize what we do have? She was using our little Nikon 4300, so it is a 4MP jpeg. I'm ashamed to post the picture - it's that bad. Any suggestions?
