Dear Jaap First I wanna congrate Ihab for his amazing works, I know him well coz he is my friend and i know his shots as well and his technics. He is addict for two things..Night shots and wildlife. For this image it's long exposure about 20seconds, of course the cars or any other vehicles will not appear, This area from cairo is very crowed, The cars appear on the bridge with the orange and red lines caused by the long exposure. I thank the luck which led me to your great profile and browse your wonderful pics which discover the beautiful Holland which one of the countries i like. Good luck
