. I did have my shutter speed way up thinking I would see some flying birds..now I realize it was set too fast without considering the wind and other elements..
I don't want to muddy the water by throwing out to much at once, but when you say "it was set too fast", to fast for what? Think about your end objective, then consider the exposure triangle to obtain that objective. As I said earlier if you're at 1/1000 and the wind is blowing so hard that the wind blown waves are blurred, and your objective was to capture water drop detail, then actually your shutter speed was to slow. I don't have an issue with ISO 640, if I wanted detail I'd bump it up without hesitation, to get the shutter speed I needed.
In looking at your image in LR, the histogram indicated a good exposure. The edit I did on your image, I only decreased the overall exposure by less then a 1/4 stop. That doesn't necessarily mean it was a good exposure for the scene. Sometimes you have situations like this where one part of the image (sky) is substantially brighter then others. In the edit I used a gradient filter to pull down the exposure of just the sky, by about 1 1/2 stops. The only way to arrive at correct exposure in camera when the sky is brighter then the rest of the landscape is to use a gradient ND filter on your lens, or bracket (expose multiple images over and under) and combine them.
