The image of Sapphire Kiu; a Hong Kong-based model (above), was made in early December 2018 on the famous (or infamous, depending on your point of view) Temple street, and will be part of a forthcoming audio slideshow (aka photo film) titled "The Songstress of Temple Street". It will tell the story of Qin Yi, a famous Shanghai singer in the 1930s, who "returns" to Hong Kong where she started her career. Some of the images were made in Temple's Street Canton Singing House and the Tin Hau Temple.
In 2014, I worked with a major car brand, a rental car company, and a couple tourism boards. So far, in 2015, I haven’t worked with anyone, though it’s mostly because I’ve been off doing my own thing. There’s a balance here between going where you want and where the money is. Unfortunately for the weight of my wallet, I’ve always just gone where I want and only take on clients like this if it’s convenient.
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.
The Yuen Po street Bird Garden in Hong Kong was built in the late 1990's after the former "Bird Street" at Hong Lok Street was demolished. It was built to preserve the spirit and popularity of the bird stalls that once were in Mongkok. The Chinese have traditionally liked to keep birds as pets, and this tradition is maintained in this small garden. Men (I've not seen a woman there except those selling birds, birdseed and live crickets) walk around; whistling at the caged birds, from delicate canaries to colorful parrots, admiring their plumage and a few walking their pets in cages.
Tip from a pro: To work with the big brands, you need to market yourself in a way that will appeal to these types of clients. The kind of architectural or food photography a hotel chain needs is very different from what a tour company that specializes in extreme travel. Don’t try to work in all genres and styles. That’s a good path to becoming an inadequate photographer. Focus only on the genre and style you love and put all of your heart and effort into it.
When you are photographing buildings, statues, or other monuments, think about what they represent before you shoot. For example: There's a large statue of Vulcan outside Birmingham, Alabama. You could make a perfectly nice image of him standing on his hill on a sunny day, but such a picture would not say a lot about who Vulcan is. A photograph on a stormy evening, with perhaps lightning in the background, would. Cannons on a historic battlefield might look better in fog than in bright sunlight. Get the idea of the subject, then think of the weather, light, angle, etc. that best communicates it.
