As an outdoor and nature photographer you may also be a camper, pulling off the road somewhere at the end of the day and setting up camp. If you are camping when out photographing your nature or adventure subjects, you may want to look at your camp as another set for photographing marketable images including the campfire scene.
However, building a fire and sitting some people around it and then shooting, may get some great shots, but I have found more success creating marketable images by waiting for the peak window of outdoor light and adding additional light from a flash. Here is the problem: if you build the campfire and use it as the light source to light the peoples face, the fire often blows out and becomes white, rather than the orange of dancing campfire flames. Here are a couple considerations for getting the best shots.
