Before we left we decided to get the torches out and see if we could get a "Ghostbusters" themed shot shining our torches through the fog. I think it turned out ok and I hope you get something out of the process involved in taking this type of shot.
One of the things to remember when out shooting at night is that anything can happen and you have to go with it. Conditions can change in an instant and it's always good to have some creative options in the tool kit.
These torch beam shots are quite popular and I've included a few more for your viewing pleasure from the last few years below.
