In 2016 I visited Stockholm and I was amazed from their beautiful Metro Stations. At that time, I was not aware that this is a popular photo spot.
I took a few shots from different stations, but this one (also known as "Belly of the Beast" by Elia Locardi) is the most martial one and hence my favorite.
It took me some time to take the shot though because I had to make it during midday and there have been many passengers. I was sitting on the floor with my Gorilla Pod and waited, and waited, and waited. But at the end, I had a few clean shots. Due to the Gorilla Pod standing on the floor, I have a rather low perspective, what I really like about this shot.
For this picture I basically just did Lightroom adjustments.
