Working at high altitude, typically in mountain ranges such as the Himalayas, Andes and Rockies, is likely to lead to excessively blue and hazy images. Above 10,000 or 12,000 feet, the level of ultraviolet radiation increases and images may be recorded much bluer than that detected by the eye. Use an ultraviolet filter to reduce the effect.

Polarizing filters may produce an almost black sky when set to maximum, so it can be worth reducing the amount of polarization or even removing the filter. Many photographers use ND grads and haze filters only, although warm polarizing filters which effectively include an 81A warm-up element are also an option.

Atmospheric pressure decreases with increasing altitude above sea level, so any container sealed at sea level may explode at high altitude. Film canisters often burst open above about 10,000 feet. Portable PCs have also been known to explode. Static discharge may also become a problem at high altitude because the air tends to be very dry.
