So regretful.
I had been shooting a football (soccer) match earlier, when it was sunny, so I had the lcd screen at the brightest.
At night I took some aurora photos and only using the lcd screen to check the results. I was very pleased, until I imported the photos to my computer, only to discover that all of the images were very underexposed.
This one was noisy, but I tried to fix it a little.
It´s still a keeper if you ask me.
