Overcast skies are brilliant for photography and I was really lucky last night that the clouds were well defined. It actually wasn't that dark but I purposefully under exposed the shots and used the flash on a tripod to pick out the cars. I need to work a bit on getting the flash to focus more on the car and less on the ground, but I'm getting there. I should hopefully be adding a couple more flashes to set up later in the year to start playing with multiple light sources and cross lighting. Man this is a more expensive hobby than dubs!
