You can offer photography services to any business in the travel/tourism industry at your destination of choice. Opportunities are plentiful, whether you're selling your services or offering a trade. Going skiing in Colorado? Get in touch with local lodges about trading photography for a free stay. Vacationing in Vienna? Talk to the local tourism board about shooting a few photos for a fee. I recently made a deal like this in Cape Town shooting a month-long campaign with their tourism board, which resulted in a promotional blog post and lead to even more work. Remember that a strong portfolio goes a long way, and as it grows, so will your opportunities.
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!
