Olga, to answer your question, No. A flash here would be much too far away to have any effect as well. Shot on a tripod with cable release and time of day was about 20 minutes after sunset so the sky was twilight providing some illumination.
I thought it was taken in Greece.Nice photograph!!Just one question , because I am not familiar with night photography.Did you use flash ?I see you used the proper film ( also Fuji superia 800 would help , or not?)I hope you will answer my simple question.With regards, Olga.
