When you travel, saving money is often the exact same as earning. Quite often, exchanging a couple images with a hotel for a free room or a tour company for a free tour is totally worth it. In fact, when I was in Southern Africa, I did this a lot. Safaris are expensive, so I’d create a couple images for a company to use for their marketing purposes in exchange for a free safari. It really is win-win.
However, now only about 10 professional street opera troupes are left in Singapore, drawing an ever-smaller audience of elderly people. The decline of street opera in Singapore was caused by its government's policy to replace dialects (such as Hakka, Hokkien et al) with Mandarin, and the slow erosion of its audience. The spread of television, movies and social media platforms exacerbated the disinterest of the younger generation in this ancient art form.
You cannot always ask permission, of course. If you are shooting a street scene or a wide shot of a market, you can't run up to everyone and ask if it's OK. In general, people do not mind this sort of photography—it's only when they're singled out that they get uncomfortable. But not always. Be sensitive to the scene in your viewfinder. If people are getting nervous, ask permission or move on.
Despite that previous statement, I do believe that the travel photography community is stronger than it has ever been. Yes, traditional forms of income-generation are dying, but the evolving world has opened up a thousand different doors for those willing to take the risks to make it in the industry. And, yes, there is a lot of competition out there in the travel photography world, but the community is strong and the amount of camaraderie rather than jealousy in the business absolutely floors me nearly every day.
This was a really informative article Hillary :) Just wish I found it sooner because just a week ago I went to the Grand Canyon to snap some photos. I didn't have this article to help, but I found a similarly useful article that provided some kind of checklist of things to do before traveling. If anyone's interested, here's what helped me out before I went to the canyon: http://www.adoramapix.com/blog/2016/10/16/photography-101-packing/#.WFH9...
