There are methods to make models comfortable. Some are already ready to act the part, while others need some handholding. In advance of the photo shoot, I provide models the story lines (or script) I want them to narrate. This is crucial, since with it in mind, they can act the role. The other method is to encourage them as they pose...not so much as how or where they are to stand, but reminding them of adopting certain poses following the script as in "show me how Meili wishes she had never met the gweilo"...or "show me how Hua is scared of seeing her aging lover...".
Another place to capture expressions are the subways; either on the platforms or in the cars themselves. My favorite images are the one of a young woman avidly watching a movie on her smartphone, while wearing a single hair roller to tame her fringe....and of the young girl who appears to be viewing a smart phone screen on an ad on a subway platform while her mother is busy texting on her real phone.
That's a terrible route. You should be able to fly to Heathrow and then it's only 12 hours to Cape Town. We don't spend 36 hours in the air. Hawaii to Atlanta is 9 hours and then 18 hours on one flight to Joburg. The best time I've ever had is 34 hours door to door total travel time from Kona to Joburg but it's not fun. I've met people on the Atlanta flight that do it every month. They normally work for some charity or in Oil & Gas. With that many miles they get business or first so that makes it a lot easier but I'm sure it still takes its toll. I enjoyed looking at your work. I need to spend more time on the road.
As with all types of photography, smart business sense is key. There are many ways to make a living with travel photography, and much of it extends well beyond your photo gear into social media marketing, content development, negotiation and sales. But the first step is to get out into the world and shoot. Start with anyplace you've been dreaming of traveling, and go! Plan ahead, do some research, and don't shoot like a tourist. Can't afford to travel? Search for opportunities in your nearest city to begin building your portfolio.
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.
Lyn's last tip is to have your own website. "Show off your work on Instagram and Facebook, but do ensure you have a good, easy to use website too. It should have some of your best work (with lots of keywords!), any specialities, and awards/competitions you have won, and your contact details. It's too easy to get carried away, add thousands of images, and forget the basics. Keep it simple."
