Hmmm... good comments so far. I think I'll try both ways and see what happens. I also have some old polaroid film that I might bring with me for test shots. I kind of feel the fire haze might not be as bad up that high anyway so I think I'll be fine. But I'll fire off a few polaroids just to be sure.

Thanks for all the good advice, I'll definitely let you all know how it went and maybe post a few shots on here when I get back.

Hope you all have a wonderful weekend!
