As a travel photographer, there is a lot of subject matter that you are going to want to photograph during your travels.  This includes the wonderful people that you meet and their cultures, interesting cityscapes and buildings that you come across, beautiful wild animals that you see on safari or out exploring, and of course the beautiful landscapes that you get to enjoy.  Out of all of these subjects that travel photographers get to photograph, my favorite by far is photographing breathtaking landscapes.  There is something so moving and awe-inspiring about photographing a landscape that is so beautiful that it hardly looks real.  If you don’t know that feeling, then I would suggest you start seeking out those landscapes and start exploring them.
