Photography of people in nature has a larger market than nature photography without people! The sales figures support that.
I am referring to general interest outdoor publications that cover a wide range of topics and are many of the magazines we all wish to be published in.
For some photographers, photographing people is challenging if not a difficult area to get into. Many outdoor photographers specialize in the natural world because the draw is nature itself and other people around is a distraction. Others prefer to shoot to the demands of the market and the market demands people.
