If you are a top notch, worldwide known photographer, it is very likely that customers from all over the world will want to use your services (for fashion, events, sports, architecture, products etc.). But as we are focusing on travel photography, commercial organizations that deal with traveling and tourism are more likely to hire you. Notable examples are hotels, tour companies, airlines and so on.
After spending the last 6 years fiddling and learning photography, my wife and I are about to move to Cambridge, UK from Melbourne. We are planning to post and write about our European trips in a capacity that is more than just telling our family what we are doing with the goal of allowing our work to eventually pay for our travel. Our first real post will be up soon, looking at our short weekend trip into the Wimmera/Mallee to visit the new Silo Art in the region. My Wife is a much better writer than I am and is currently editing!
