Tent vs bag

A changing tent is essentially a film changing bag with a support structure. As opposed to a bag, a tent provides a roomier interior that allows delicate tasks to be performed without fabric plied against your hands. The more spacious interior heats up slower, reducing hand sweating improves comfort.

On the other hand, a typical film changing bag is about a quarter or a third of the price of a comparably sized tent. A tent is also bulkier and heavier to transport, so it might not be ideal for a backpacking setup. To counter this, some tents’ poles can be removed, effectively turning them into changing bags, albeit still at a higher cost. On the other hand, you can put a support like an open sided cardboard box inside a changing bag to simulate a tent. It all comes down to what works for you, your workflow and budget.

Tent vs box

A film changing tent can be seen as a packable, portable film changing box. In a way, the tent provides the benefits of the box with the portability of the bag. Basically, if you have a tent, you probably won’t need a box as well, unless you need one for a specific purpose.

A changing box can be more suitable for wet processes, like wet plate photography or developing, as any spills can be more easily cleaned. If you are going the DIY route, a changing box is the easiest one of the three options to construct. Furthermore, a box can easily be customized to suit a specific process. For example if you are working with orthochromatic materials, you can install a red safelight filter as a viewing window through which to monitor the process.

Film changing tent storage and maintenance

Because working in the tent for prolonged periods can cause perspiration on your arms, humidity can build up in the tent. This can be further exacerbated if you perform any developing or other wet processes inside the tent. Excess humidity can lead to fabric deterioration or mold. Harrison tents have a known issue with the silver outer fabric of the tents deteriorating from prolonged exposure to high humidity.

To ensure long-term performance, it’s important to store the tent properly when not in use. Make sure to wipe up any spills or moisture spots after use. Harrison recommend storing the tent loose (unrolled) in a cardboard box or paper bag. Do not store in a damp area or one that experiences wide temperature fluctuations.
