The opportunity is equally open to all of the recognized photographers. There's a difference between their product and like in your example Eddie Marine. This is their product. They're giving it away. When you see a photo in Powerboat from Jeff or Tim or Jay, Powerboat paid them for that. These guys put their product here for your enjoyment at no cost to us.
Nothing is free. None of these guys is doing this solely because they like renting helicopters to photograph boats. It costs big bucks. The tradeoff is like this- you get pictures to enjoy, they get exposure to potential customers, we get happy members.
