Isolated Pockets

This took quite a while to do. Attracted by streetlights, normally taken for granted, I set about photographing the different designs, and the colours they emitted. The problem was that the light they produced, obscured the structure, and the photograph was unusable, (chromatic refraction); so I photographed them during the day, and added the light artificially, (you can tell, is it that obvious?). I took some time to think what I should do with them. Eventually I found a photo I had taken in Norway, and added a different skyline. I darkened the landscape to give some contrast to the lights. I liked the meandering road, which lent itself to the diminishing groups of streetlights. What is the collective noun for streetlights?
