This is a quick view in one of my older projects. I made these pictures almost 25 years ago, fully analogue, no digital editing.
I had just moved to the city of Stockholm and set up a project to take at least one night time stroll a month with camera and tri-pod. It was quite difficult to take night time pictures during the summer months with light 24/7.
Here come some pictures I took, that have one thing in common: the pervasive, warm yellow color of many old buildings. Combined with the common natrium tinted, yellow lights of the time the color often looks the same, even if it differs in daylight.

As you can see, I use a wide aperture to get almost everything in focus, at the expense of long exposure time. The light-polution of the city is reflected back from the cloudy sky and even the birch tree gets a yellow tint. I choose a perspective looking upwards, even if it distorts the lines of the architecture, since I wanted to capture the illuminated branch, so that it guides the eye towards the church.

Again, I worked with a wide aperture and long exposure time, as can be seen in the drawn out reflections in the water. I like of the flagpoles in the center of the picture go in parallell with the reflections of light in the water, they almost look like an extension of each other.

A contrast between the illuminated graffitti and the dark street, where the overhead lights lead your eye towards an unknown distance.
