I actually saved this one. My lens were completely fogged when I took this shot. As soon as I saw it approaching I pulled off my lens cover only to find the unpleasant surprise. I quickly whipped it off on my shirt but it immediately re-fogged. so I took the shot.
I did a number of adjustments to it to save it. it still appears a bit foggy and I took the colors out as well.
I believe I saved this one.
