Watching the northern lights with naked eyes was a unique experience for me because they are kind of different than what you see in photos.

They are very dim and flow very slowly. Human eye can easily see them with their details in real time, but to capture them in photos or videos, long shutter exposure is needed. As a result, they look bright and blurry. The videos are even worse; they are all time-lapses which are bright, blurry, and fast moving. In reality, you have to wait minutes to see the light changing its shape and flowing around.
