Here’s a shot from the recent aurora borealis photo tours in March; I set up the tent for the shot, it was merely a prop. It took a few times to get the balance right with the headlamp for the exposure. Trial and error is really the only way to make this work.
Foregrounds matter when shooting the northern lights, as they do when shooting just about anything. Adding anything of interest to the foreground can really help balance the colors and dynamism of the northern lights overhead.
