A pretty picture is not enough. It needs to be high quality and it needs to be original. For magazines, you need to consider issues such as leaving space on the image for word placement, positioning your subject off-centre so it doesn’t fall down the page join, and possibly placing the subject on the right-hand side of a landscape shot for maximum impact.
Get lost. Wander down alleys. Sit in cafés and watch life pass by. Don't eat where the tourists do, but where you see locals. Just set off down a street and see where it leads. Look around the bends, over the rises. Get away from the crowd. I find that if I meander away from the tourists and tourist sites, away from what is too familiar and comfortable, it's much easier to adapt to the rhythm of a place, and to be more observant.
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.
The patrician-looking (and rather taciturn) sadhu in the top photograph did tell me that he had a family, had held a managerial position in the Indian Railway from which he earned a pension (now paid to his wife), but had decided to detach himself from temporal life and was currently studying the Vedas. These are the oldest scriptures of Hinduism. He was the embodiment of a real sadhu who had really espoused the Vairāgya, and was far different from the "sadhus" I encountered on the ghats of Varanasi (below) almost 8 years later.
In contrast with most of my peers, I seldom use Photoshop and have never used Lightroom. However, I rely on three post-processing/editing apps as my tools of choice...these are Color Efex Pro (originally of Google and now part of DxO Software, Iridient Developer (the raw image format processing software for macOS, and well known for its ability to process Fujifilm X-Trans raw files), and lastly ON1 Photo Raw ( a raw processor, photo editor and plug-in collection all in one).
Besides the travel publications like National Geographic Traveler, Conde Nast Traveler, etc., the demand for this genre exists in industries like Travel, Photo Education, etc. Many travel photographers are today leading photo-tours through companies such as Intrepid Exposures, utilising their knowledge of unique travel locations, experience of working as professional photographers and using this to help travel enthusiasts take great travel images during their trips. Many others are doubling up as educators in the field of ambient light photography. Some of them are doing assignments which intrinsically use their strengths, e.g. shooting exteriors or interiors of buildings for architects and interior designers. Photographers like Steve McCurry are often commissioned to shoot commercial advertising work using their skills from travel and documentary photography to produce powerful advertising images.
"Back when we started Wanderlust, we would invite photographers in with their portfolios. Nowadays, although we do commission some work, we increasingly use online stock libraries to find images for this website and for our magazines. On the one hand, they libraries have a wide range and make it very easy to search. On the other hand, we can find ourselves wading through pages of very average shots that don't offer anything different or fresh. And, so often we struggle to find what we need due to poor tagging by the photographers."
Above all, work the situations over. Never be satisfied with your first view of a place or the first frame you snap. It's always possible—and usually likely—that you can come up with something better. Why else would painters make sketches? Get closer, then get closer still. Try different angles, different lenses. Wait for the light, wait for the crowd, wait for a bird to land on the tree branch. Never be in a hurry to get somewhere else. Tell yourself that nothing is more important than getting the best you can get out of the situation you are in. Once you've exhausted every possibility you can think of, you can start working on the next one.
Always have your camera with you and always keep your eyes open. Serendipity plays an enormously important role in travel photography. You never know what you are going to run into, and you have to be ready. Many times you will see what could be a good photograph but decide that the light is not right, or there are no people around, or too many—something that means you will have to come back later. But sometimes you get lucky. You happen to stumble upon a scene at just the right moment. If you forgot your camera, are out of film, or your digital card is full, if you have to fumble around getting the right lens on, the moment may be gone before you can recover. This is true whether you are doing street photography or visiting a natural or man-made site. Mountains, trees, monuments, and other static subjects are, of course, not going to go anywhere, but the ray of sunshine, the soaring eagle, or the embracing couple that add the needed element to your photograph are unlikely to hang around. Think of it as hunting—whenever you leave the confines of your camp, you should be ready and able to capture whatever pops up.
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.
