I was on the beach in Nantucket a day this summer when quite suddenly, a thick fog rolled in perpendicularly to the shore. It was quite dramatic and I regret that I did not have my camera with me, only my fishing rod. I've read that using a blue filter for B&W film, an effect of fog and haze in the distance will be achieved. Is this true and how dramatic is this effect? If anyone has examples of the magnitude of this effect, I'd would appreciate it if examples can be posted.
