One Bag, Two Roles: A Travel System for Consulting and Film Photography
There is a specific kind of travel that does not fit the usual one-bag advice. It is not pure business travel — you are not just a laptop and three shirts. And it is not pure photography travel — you are not free to build the trip around the camera. It is both at once: arrive credible for a client engagement, and carry a film camera through whatever city the meetings happen in, on the same back, in the same bag, for the same week.
This is the system I have converged on, and — more usefully than a packing list — the constraints that shaped it, because the constraints are what transfer.
The constraint that defines everything
A consulting day and a photography walk want opposite things from a bag. Consulting wants you to look composed, organised, unremarkable in a professional setting — nothing that reads as “tourist.” Photography wants quick access, willingness to get the bag dirty, and the freedom to not care how it looks on the street. One bag has to satisfy both without compromising either to the point of failure.
The resolving principle: the bag must read professional when closed and function photographic when open. Externally restrained, neutral, nothing that screams camera bag or tech-tourist. Internally organised so the camera comes out in a second and the work setup deploys cleanly. The whole system follows from refusing to pick a side on this.
A second constraint, downstream of the first: 30–35 litres, carry-on, one bag, no exceptions. The discipline of a hard volume ceiling is what forces every other decision to be deliberate. The moment you allow a second bag, the system collapses into “bring what might be useful,” and the dual-role clarity is gone.
The aesthetic is a function, not a vanity
A note that sounds like style but is actually function: an all-black, minimal, unbranded kit is not just preference — in this dual-role context it is the thing that lets one bag pass in both worlds. Black and unmarked reads as professional in a client setting and disappears on the street (a flashy bag attracts attention you do not want while carrying a camera in an unfamiliar city). The restraint is doing security and credibility work simultaneously. Form following two functions at once.
This is the through-line with how I think about everything else — the visual language at johlem.com, the minimalism in the tooling. Restraint is not decoration; it is what makes a single thing serve multiple roles without announcing any of them.
The structure of the kit
Rather than a brand list (which dates instantly), the structure — the categories and the reasoning, which is what actually transfers:
The work layer. The minimum that makes you credible and functional for the engagement: the laptop, the one set of cables that matters, whatever documents must be physical, and one outfit that reads professional and survives being the only one. The discipline here is one — one charger, one adapter, one professional outfit that can repeat. Redundancy is the enemy of the volume ceiling.
The camera layer. A film body and the discipline of one system — for me a rangefinder and a single focal length, because the constraint of one lens is creatively clarifying and physically minimal. Film stock for the trip, chosen before leaving because you cannot reliably resupply. The camera layer is deliberately small: the dual-role only works because the photography kit refuses to sprawl. One body, one lens, the film, nothing else.
The shared layer. Everything that serves both roles: the clothing that works for a meeting and a long walk, the toiletries, the universal items. This is where the volume is recovered — items that pull double duty are how 30–35L holds two roles. The more an item serves both purposes, the more it earns its place.
The packing logic: minimise the role-specific layers (work, camera) to their irreducible cores, and maximise the shared layer’s double duty. That ratio is the whole trick.
What the dual role teaches
The interesting part is not the gear; it is what the constraint forces you to learn:
One of everything is almost always enough. The instinct to pack redundancy — a backup charger, a second lens, an alternate outfit — is what kills one-bag travel. The dual-role version is even stricter, because two roles double the temptation to bring backups. The discipline of one per function is what makes the whole thing fit, and it turns out to be sufficient far more often than fear suggests.
Constraints clarify rather than limit. One lens makes you a better photographer for the week, not a worse one — you stop choosing and start seeing. One professional outfit makes packing trivial and your appearance consistent. The volume ceiling makes every decision deliberate. The constraint is the feature.
A system beats a list. A packing list is brittle — it breaks the moment the trip is slightly different. A system — minimise role-specific layers, maximise shared double-duty, hard volume ceiling, professional-closed/functional-open — adapts to any version of the dual-role trip. Learn the system and you never need the list.
The takeaway
The consulting-plus-film-photography trip seems to demand two bags because the roles seem incompatible. They are not — they are reconcilable by a single principle (professional closed, functional open), a hard volume ceiling that forces deliberation, and a packing ratio that shrinks the role-specific layers to their cores while maximising shared double-duty.
The broader lesson, which is really why I find this worth writing about: the same restraint that makes one bag serve two roles is the restraint that makes good tooling, good design, and good security architecture. One thing, deliberately minimal, serving multiple purposes without announcing any of them. The bag is just where the principle is easiest to see.
