a filter?

for skiing shots.

Probably a red filter due to the dark color of the sky.

There are lots of effects going on there. You'll have to be more specific.

I'd say it was a pretty standard shot, possibly with a circular polarisor. The contrasty look has been achieved because of the two extremely bright aspects - the sun and the snow. The person who took it probably exposed from the snow/sky or just got lucky in auto mode. Any specific thing you like about it?

The most significant thing in this shot is the fact that it's backlit. Had the shot been taken from the other side of the climber, it would have looked pretty normal.

i LOVE the extreme contrast in it.

alot of the contrast is related to the exposure and subject matter, but a polarizer or red filter might get you closer to what you're looking for. if you develop and print your own film you'll obviously have more control over that contrast later
