It's been suggested there are too many nature photographers, all taking the same kinds of photos. With digital photography becoming more and more affordable, and easy, it's possible to take better photos with entry level knowledge. The challenge is to take photographs which are different than other photographers, photos which stand out from the crowd. Tagging that idea, it's also important to be able to get your message across through your photographs. One photographer who is concerned about the affect of global warming on the wildlife populations suggests it's extremely difficult to tell the tale of potential dangers to the polar bears, for instance, when a gorgeous coffee table book about polar bears shows them in their natural environment, on what looks like plentiful miles of ice. Mixed messages. Photography is fun, rewarding, and an extremely useful medium for educating others on a variety of issues and topics. Spread the word...and take some pictures!
