First light fog

I had been on an all nighter shoot with a couple of friends around London finishing at 4am. I had an event in the city centre the same day. When i had left my 2 friends i found a place to warm up out of the cold when I could see fog coming in. As soon as I saw the start of blue hour I could see how intense the fog really was. So I put back on my cloves and coat and headed straight back out into the cold. So at the moment of taking this phone I had been awake for 24 hours and had been out shooting for almost 12 hours. Safe to say photography is more than just a passion haha
