It's best to ask permission if you want to photograph someone, especially if you are working in close. Engage them before you pull out your camera. Learn at least how to say "hello" and "May I make a photograph" in the local language—just showing that you've made a little effort helps. Explain to them what you want to do and what it is about them that made you want to make a picture. If approached in an open and friendly manner, most people will be agreeable—many are flattered that someone has shown an interest in them and what they do. In places where there's a lot of tourism, you may run into people who are tired of being photographed—many tourists are not courteous enough to ask permission, and local people can come to feel abused and exploited. The only way to overcome this is to spend time with the people or to go to parts of the place less frequented by tourists.
There's much more to becoming a travel photographer than exploring exotic destinations and clicking your shutter. Getting up at stupid-o-clock to catch the perfect sunrise, carrying a camera that’s heavier than four backpacks, skipping meals in the quest for perfect light, and missing out on the travel experience because you’re too busy taking photos, are just a few of the downsides.
Hi Claire, thanks for your message. That’s correct, it’s not possible to upload photos from your computer to Instagram however it’s quite popular to get around this by emailing the photos to yourself, then opening the email on your phone and storing the attached image in your phone’s library. This then allows you to post to Instagram. Alternatively there are a number of apps or plugins that allow you to upload to Instagram, most however will require payment. This is one I suggest looking at ‘LR/Instagram‘ but I can’t promise anything as I don’t personally use this method.
I have found Alessandro Bergamini's China gallery to hit all the right notes in that regard. Most of his images were made in Guizhou; a province located in the southwestern part of the country, and well known for its traditional rural villages, inhabited by minority groups like the Miao and Dong. Other images in the gallery were made in Guangxi , another autonomous region bordering Vietnam, and home to the famous cormorant fishermen of Guilin. I haven't been but I read that even though the water is too polluted now for fishing to be sustainable, these fishermen are catnip for many photographers, and earn their living in that fashion.
