Hi All:

I read somewhere that when photographing from high altitudes such as in the Tetons, Rockies, Smokies
(clingman's dome), it's best to use some sort of UV correcting filter because the additional UV found in the
higher altitudes affects film differently than when shooting closer to sea level.

Anyone had any experience with this? If you have, would you mind sharing your experiences?

Thanks in advance,

You absolutely must use at least a skylight filter or everything (especially
the sky) will be washed out.  If you are shooting black and white, a light
yellow or red filter can accomplish the same, and increase your sky contrast
incredibly.  BTW, a polarizer will also do the trick, but I prefer filters
personally.

I live in Conifer, CO at 8500ft.

I have not found this to be true.  

And the contrast of everything else in the photo. Red is dramatic. Use these
filters for effect, not for altitude.

Using a poparizer will help darken/add contrast to sky/clouds only if polorized
light is available. Otherwise, you loose two or more stops, and gain zip.

My experience,  work on balancing exposure between the sky, and other objects.  
Washed out skies are an exposure, not altitude problem.  Try a graduated filter
if the sky is a few stops brighter than the foreground.  Use a polorizer to
darken the sky if polorized light exists.

I'm not suggesting that using UV/skylight or any other filter is bad, I just have
not found that shooting at altitude requires any special filter use.
