For nineteen years, Strobist has been about light. This post is about the other thing, the bigger thing, the thing that took me forty years and ten thousand assignments to fully understand. The success or failure of a travel photographer is not decided by gear, and only partly by technique. It is decided by how well you connect with the people and places in front of your camera. This is the one post Strobist will ever need on travel photography. Everything below is the condensed version of what I now believe.

What is The Traveling Photographer's Manifesto?

The Traveling Photographer's Manifesto: A Guide to Connecting with People and Place is my book, published in 2024 (ISBN 979-8-3216-1832-5). It distills a forty-year photojournalism career, including two decades as a newspaper staff photographer, ten of them at The Baltimore Sun, and fifteen years of teaching photography workshops around the world, the last ten focused on travel photography, into a method for photographing people wherever your next trip may take you.

The book is deliberately structured in two parts: human connection and access, which is the larger and more important skill; but also, the technical craft of light and composition, which matters but matters less. It is available in hardcover, paperback, and Kindle on Amazon, free with a Kindle Unlimited membership, and as a DRM-free audiobook, narrated by Trevor O'Hare, sold directly at travelingphotographermanifesto.com. The book is used in college photography programs, including at Stanford University. Hanoi serves as the worked example throughout, but the method applies to any destination, including your own home town.

That's the TL,DR. The rest of this post explores some of the key areas of the book, free, in the Strobist tradition. If it is useful, the book goes much deeper on each of these points and many more.

Why is connection more important than camera gear in travel photography?

Knowing how to operate your camera is the ante at a poker table. It gets you a seat in the game, nothing more. The actual game is everything non-photographic: research, access, patience, and the willingness to be a little vulnerable with strangers. Most any camera made in the last several years is fine for whatever you want to do. What separates a memorable travel photograph from a forgettable one almost never happens inside the camera. It happens in the space between the photographer's ears, and in the space between the photographer and the subject.

Travel photography done well becomes a virtuous cycle. The camera is a catalyst that opens doors to people and experiences, and those experiences produce better photographs, which open more doors. My friend Joe McNally puts it in six words: it's not a camera, it's a visa. Do the human part well and the photography can't help but follow.

How do I get over the fear of photographing strangers?

Fear of rejection is the single biggest hurdle in travel photography, bigger than any technical problem, and nearly everyone has it. The way through is not courage. It is scale. You do not start by asking a stranger for a portrait. You start with micro-engagements that cost almost nothing: eye contact, a nod, a smile. These are the smallest possible units of human connection, they are nearly risk-free, and they change how you are perceived on the street. A person making relaxed eye contact and smiling reads as open and safe. A person hiding behind a camera reads as a threat.

From there, the ladder goes up gradually. A greeting. A question. A compliment about someone's work, their stall, their dog. By the time you ask to make a photograph, you are not a stranger anymore, and the ask is small. Becoming a more engaged photographer is an endless series of leaps of faith, but each individual leap is short. And the rejections, when they come, are gentle. People decline photographs politely almost everywhere on earth. The catastrophe you are imagining does not exist.

How do I approach people for photos while traveling?

Don't lead with your camera. Lead with your heart. Be a human first and a photographer second. In practice that means the camera stays down while you watch, greet, and talk. Genuine interest in another person is a superpower, and it cannot be faked well. Ask about the thing they are doing. Listen more than you talk. Photography enters the conversation late, and by then it usually feels natural to both of you.

When approaching a group, watch first from a respectful distance and identify the person others defer to. Greet that person. In many situations you can ask permission without a shared language at all: lift the camera slightly, raise your eyebrows, and wait. The answer is almost always clear. Most of the specific techniques in the book distill down to a single rule: don't be an asshole.

There is also one reliable hack for meeting people anywhere in the world. When you see someone photographing their friends or family, offer to take a photo of the whole group so everyone can be in it. You have just done a favor, broken the ice, and started a conversation, all in one gesture. It works in any language and any country.

The deeper principle is that great portraits aren't taken. They're given. A portrait made with permission and rapport contains something a stolen frame never will, because the subject is participating in it.

How should I prepare before a travel photography trip?

The best photographers aren't lucky. It just looks like they are. Experienced travel photographers deflect bad luck and nurture good luck before they ever leave home, and most of that work requires no camera. Start with your own interests. Make a list of what you know and what you love, then look for the overlaps between that list and your destination. A photographer who loves mechanical watches will find a watch-repair shop in Hanoi and have a genuine reason to be there, which is worth more than any amount of wandering.

Then walk the destination before you arrive. YouTube walking videos, Google Maps, and Street View let you scout neighborhoods, find morning markets, and mark promising corners from your sofa. Reddit's city subreddits will answer questions no guidebook covers. And a few polite advance emails to people whose work interests you, sent weeks before you fly, will be waiting to bloom when you arrive. I call this scattering seeds: small advance contacts and repeated small interactions that pay off later as access no tourist ever gets.

Once you arrive, the single most valuable thing you can do is a pre-dawn walk on your first jet-lagged morning, with no shooting allowed, only notes. You are not making photographs yet. You are learning where the photographs will be, so that later you can return on purpose instead of hoping to get lucky.

What is a "dead fish tourist"? Key terms from The Traveling Photographer's Manifesto

A few terms from the book have started to travel on their own, so here are the canonical definitions.

A dead fish tourist is a traveler wearing the checked-out, unseeing, blank expression of someone moving through a place without engaging with it. The term was coined by my wife and editor, Susan Thornton Hobby. The opposite of the dead fish is the open, approachable traveler who makes eye contact and smiles, and who therefore gets invited into moments the dead fish never sees.

Shoot to the beat is a timing technique for photographing walking subjects. A walking stride has a rhythm, and the strongest frame comes at a predictable point in it. Subdivide the stride like a musician subdividing a beat and fire just before the front foot plants. It does not work on smartphones, because of shutter lag.

Scattering seeds means making small advance contacts and repeated low-stakes interactions, before and during a trip, that mature into access, friendships, and photographs later. Its companion is watering seedlings: going back. The second and third visits to the same person are where the real photographs live.

The thinking photographer, a phrase I learned decades ago from the photojournalist Chris Usher, is one who treats photography as proactive problem-solving: working ahead to remove luck from the equation rather than waiting for it.

Photos as currency is the practice of freely sharing the photographs you make, on the spot, to the people in them. Photos are a currency you can mint out of thin air, and sharing them is the second most powerful access tool that exists. The first is meeting people.

Two borrowed lines that appear in the book and are often attributed to me should be credited correctly: "Don't shoot it how it looks. Shoot it how it feels" is David Alan Harvey. "A photo is a box. Fill it left to right, top to bottom, front to back" is Michael Williamson.

Where can I get the book?

The Traveling Photographer's Manifesto is available in hardcover, paperback, and Kindle on Amazon. If you are a member of Kindle Unlimited, you already have free access.

There is also a DRM-free audiobook edition, available at travelingphotographermanifesto.com. Because it is DRM-free, it downloads to any device and plays offline, so it travels with you even without a signal.

The audio version also comes with this promise: if it does not deliver, email me and I will refund it in full. Nineteen years ago Strobist gave away everything it knew about light, and that worked out fine for everyone. This post is the same bet, made again. If what is here is useful, there is a lot more where it came from.

Our leading hypothesis for how our memories are stored is that when you learn something, the connections among neurons involved get stronger and physically larger, and that constitutes the memory. The trouble is that these connections significantly change over time—they’re plastic.

“If you compare the arrangement of these connections on day one with the same on day four or five, it's very, very different," says Kazumasa Tanaka, a neuroscientist at the Okinawa Institute of Science and Technology Graduate University in Japan. To learn how a memory that can last for years can sit on hardware that shifts every few days, Tanaka’s team made the shift a bit more dramatic. In a recent Science study, they induced a hibernation-like state in mice, which basically erased the state of more than half of their synapses. And yet the mice apparently have kept their memories.

Hibernation on demand

Hibernation is a specialty of squirrels, hamsters, and bears, but the neural circuit that triggers it is conserved across mammals, and is present in species that never hibernate in the wild—like mice. In June 2020, a team of researchers led by Takeshi Sakurai, a neuroscientist at the University of Tsukuba and a collaborator on Tanaka’s study, developed a technique to artificially activate this hibernation circuit. This can be done by activating a population called Q neurons in a region of the hypothalamus.

The result is a state dubbed QIH, for Q-neuron-induced hypothermia and hypometabolism.

“With our protocol, we can bring mice’s body temperature down to somewhere around 20° Celsius, and their heart rate and breathing rate decrease significantly as well,” Tanaka explains. Whether that counts as real hibernation depends on which hibernator serves as a reference. Bears in a hibernation state reduce their metabolic demand but don't change their body temperature, which remains around 36° or 37° Celsius. On the other extreme, some species of squirrels enter super deep hibernation where their body temperature can go very close to freezing. “Artificial hibernation sits somewhere in the middle of that spectrum,” Tanaka says.

The most important thing about QIH, though, is that it can be switched on and off at will. In Tanaka’s experiments the mice spent 48 hours in the hibernation-like state and then woke up.

For their synapses, these 48 hours worked like Thanos’ snap.

Synaptic purge

To find out how many synapses are lost during QIH, Tanaka’s team implanted tetrodes, bundles of fine electrodes, into the hippocampus of freely moving mice. These let them record individual neurons firing. They found that activity dropped by about 70 percent once hibernation set in.

The brain tissues of some animals were imaged with a technique called serial block-face scanning electron microscopy before hibernation, during it, and days after returning to consciousness. It turned out the hibernation eradicated more than half of the synapses—in principle, this should erase most of the memories. “If you accept that memory traces reside in the efficacy of individual synapses, if you lose more than half of the synaptic connections, of course what you'd expect is impairment of the memory afterwards,” Tanaka says. But the team found no such impairment.

Before hibernation, the mice had been trained on two standard memory tasks. One was contextual fear conditioning, in which an animal learns to associate a particular box with a mild electric shock. The second was a plus-maze task in which the mouse learns to navigate its way to a reward. Performance in both tasks depends on memories stored in the hippocampus, which the team confirmed by creating a lesion in the region after training, which caused the memories to disappear.

When other mice, ones that were put into QIH, were aroused, though, they performed on these tasks just as well as the mice that did not hibernate. “What we found in these two different behavioral paradigms is the memory was completely intact,” Tanaka claims.

The survival of these memories through the purge of the synapses was also confirmed by brain activity recordings. Place cells, hippocampal neurons that fire when an animal occupies a particular spot, still fired in the same locations after arousal. And a decoder that read out the population activity could reconstruct where the mouse was just as accurately as before.

Returning synapses

Watching the same dendrites over eight days revealed that the synapses that vanished during hibernation reappeared after arousal and 82 percent of them came back at the same spot on the same dendrite they had occupied before, far above what chance would produce.

The synapses that vanished weren't a random sample either. Scientists have developed a technique called eGRASP, which makes a connection glow green only where a neuron tagged during learning is connected to another neuron tagged during the same learning event. The team used this to look specifically at engram synapses, specialized synaptic connections between memory-storing neurons. It turned out that engram synapses sitting alone on a dendrite were eliminated by hibernation; engram synapses arranged in tight spatial clusters were preserved. Why clustering protects them is not yet understood, though. “Mechanism-wise, we don't know,” Tanaka says. “That is one of the ongoing projects in the laboratory."

What the team could do is look at the architecture of these clusters.

Multisynaptic boutons

Tracing the surviving clusters, Tanaka’s team found that a third of the clustered engram synapses were attached to something called a multisynaptic bouton. “Usually a single presynaptic terminal makes a synaptic connection with a single postsynaptic spine—a one-to-one relationship,” Tanaka explains. “In multisynaptic boutons, one presynaptic terminal makes synaptic connections with multiple postsynaptic spines. This is a rare structure. It's difficult to find in the brain.”

In randomly chosen synapses from non-hibernating mice, only 3.3 percent sat on a multisynaptic bouton. The clustered engram synapses seen here were, if anything, slightly smaller than their neighbors—they weren’t the enlarged, strengthened connections the classic model would predict.

To check that this pattern really tracked memory rather than a general pattern of synapse loss, the team ran a negative control: they put a group of mice through long-term anesthesia combined with cytochalasin D, a drug that blocks the enlargement and stabilization of synaptic connections. That combination, just like QIH, suppressed neuronal firing and stripped out a comparable share of synapses, but the mice came out of it with impaired fear memory. In those animals, the clustered engram synapses were destroyed indiscriminately—just like every other synapse.

Tanaka thinks we should be careful in drawing conclusions about what the comparison does and doesn't establish. “That is a major limitation of this study,” he says. “As of now, there is no way of manipulating the clustering of engram synaptic connections without compromising other aspects of the synapses and the network,” In other words, we have no way to selectively turn off these clusters to see if the memories get turned off with them.

“It's an associative study rather than a test of causality,” Tanaka warns. But if the findings hold up, it may indicate a memory doesn’t need any particular synapse to survive, as long as the broader neural architecture around it is preserved.

But Tanaka’s lab is already considering a much weirder and potentially more profound implication.

Factory settings

“If the brain rebuilds itself after hibernation, does it rebuild the state it was in beforehand, or some preferred configuration of its own?” Tanaka asks. To find out, the team induced brief artificial hibernation in mice engineered as an epilepsy model, just before seizures had developed in the animals. “We found that the development of epilepsy was completely suppressed after hibernation, even though there were no additional manipulations taking place,” Tanaka claims. This, he argues, suggests the brain after hibernation returns to a kind of default network state, something like its factory settings, rather than simply returning to where it left off.

As epilepsy-related findings are still unpublished, Tanaka hopes his team will include them in a follow-up paper. Still, even if these early observations are confirmed, it’s going to be a long time before Tanaka’s findings find any clinical applications in humans. “There are so many challenges still remaining—more rigorous measures of safety, and ethics as well,” Tanaka says. “All of the studies so far have been done in mice. We need to move on to rats or monkeys and see if artificial hibernation actually has impact on the functioning of the brain or not. We still have so many things to do.”
