  Camera On Tripod


The Northern and Southern lights are photogenic, but elusive, subjects. During a bright display, use a fish-eye (8 mm to 16 mm), wide-angle (24 mm to 35 mm), or normal (50 mm) lens set at f/2.8 or faster.

Use at least an ISO 400 film and expose for 10 to 40 seconds. There is no single correct exposure—a shorter exposure freezes the rippling curtains of light, but may not pick up the subtle shades of red, green, blue, and purple that film can record but the eye usually cannot see.
