Whether you're licensing photos through an agency or you're working with local businesses, destination photos sell. If you're just starting out, consider uploading your best work to sites like 500px, where you can offer your images for license quite easily. If you already have a strong portfolio of work, consider applying to Stocksy, the most reputable agency in the stock photo business. Interested in reportage?

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!
This year and I signed a long-term travel photography contract with Cape Town Tourism, the official tourism board in my favorite city in Africa. Meanwhile, I've sold tens of thousands of image licenses through multiple agencies over the years, host local workshops and photowalks in the cities I visit, and I'm constantly working on partnership and sponsorship deals behind-the-scenes. Even my travel photography website works hard for me, as I often get offers and inquiries directly from visitors.
