Thank you very much, Ace! I was lucky enough because I didn't have my tripod, but there was a railing in front of the building, where I could hold the camera fixed for the time of the long exposition. I could use a flashlight of course, but I don't like that, since it really destroys the atmosphere - it makes almost day out of night.
You got an interesting result over here, Night photography is my most beloved part of Photography, you are doing great, keep up the good work, Regards,
