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.
Travel photography as a genre is one of the most open in terms of the subjects it covers. Many travel photographers specialise in a particular aspect of photography such as travel portraits, landscape or documentary photography as well as shooting all aspects of travel. Much of today's Travel Photography style is derived from early work in Magazines such as National Geographic magazine from photographers such as Steve McCurry. This genre of photography entails shooting a wide variety of subjects under varied available conditions, e.g. low light photography indoors, available ambient light photography for exteriors of buildings and monuments, shooting on the streets where sometimes conditions may be hostile, capturing moments which rarely recur, capturing the magic of light while shooting landscapes, etc.
Knowing how to use your camera is essential to success as a travel photographer because more often than not, it’s those spur of the moment shots that generate the goods. If you can quickly adapt to the surroundings and know what settings to change in a split-second in order to capture a moment, you’re in with a pretty good shot of becoming a professional photographer.
It was in 2006 when I traveled to the sacred city of Varanasi for the third or fourth time; this time in search of real sadhus rather than those I encountered on the ghats of the river Ganges. The more photogenically flamboyant of those would "earn" a few rupees from tourists and photographers who sought to augment their inventory of exotic portraits of these characters; perhaps paying them a tidy sum if they agreed to be photographed in a rowing boat or next to a temple.
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.
I think that there are more people wanting to learn photography than there are people that want to buy images. And for that reason, teaching has become a major source of income for a large number of photographers. In fact, some of the world’s highest earning photographers aren’t always the most talented, but the ones who can teach effectively. Lots of photographers sell books, video tutorials, and host workshops to help supplement their income.
Make use of people to give your images life and scale. If the facade of a particular building appeals to you, the picture may be that much better if you show people walking in front of it. They will give it scale and also let viewers know what sorts of people live there, how they dress, and the like. An outdoor café may be more interesting crowded with people than empty.
