Digital or physical disposable cameras for your event?

Both promise the same thing: photographs from the guests' side of the room, taken by people nobody hired to take them. The crooked ones, the ones from under the table, the ones from the end of the night after the photographer has packed up.

So the real question is not which is better. It is which way of going wrong you would rather live with.

What you are actually choosing between

Physical: a single-use camera on each table, 27 exposures, developed afterwards.

Digital: your guests' own phones, with an app that gives each of them a limited roll and keeps the photos hidden until a set time.

Done properly, both keep the two things that make disposables fun: you cannot take a hundred photos of the same moment, and you cannot look at them straight away.

Who ends up taking the photos

With physical cameras, the photographer is whoever happens to be sitting nearest one. Cameras drift between tables. Some tables never touch theirs; others hand it to a nine-year-old who uses the whole roll in ten minutes. You get a lot of one corner of the room and nothing from the rest.

With an app, every guest already has a camera in their pocket, and each one gets their own roll. The host decides how big that roll is, from a handful of shots to more than you would ever use. Coverage spreads across the room because the cameras do.

What can go wrong

Physical. A lost camera is a lost roll, and nobody notices until the cameras are collected. The flash reaches a couple of metres, so a dim reception produces a lot of dark frames. And every problem shows up a week later at the lab, when it is too late to fix.

Digital. Phones run flat. Some guests will not scan a QR code, however nicely you ask. And venues in barns, cellars and fields often have no signal. That last one matters less than people expect: in the Posy app, a photo taken with no signal is kept on the phone and sent as soon as the connection comes back. There is more on that in what happens when the venue has no signal.

The guests who will not join are the real weakness of any app. Nothing technical fixes that.

The wait

Physical cameras come with a built-in wait, but it is an awkward one. Someone collects the cameras, takes them to a lab, and a week or two later one person sees everything first and has to share the scans with everyone else.

With an app, the host picks the reveal time. The next morning is a popular choice. The whole album opens for everyone at once, at the full resolution of the phones that took it, and each guest can save what they want. The wait is still there. It just ends at the same moment for everyone.

The look

This is where physical cameras win outright. Film grain, harsh flash and that washed-out colour are why people want disposables in the first place, and they come from real film.

An app can only approximate it. In Posy, the host picks one look (Original, Vintage or black and white) and it is applied to every guest's photo, so the album reads as one roll rather than forty different phones. That is a good approximation. It is not film.

The waste

A single-use camera is a plastic body and a battery that each get used once. A phone your guests already carry adds nothing. It is not the main reason to choose either way, but it is worth knowing.

So which?

Choose physical cameras if the object is the point: you want something on the table to hold and pass around, your guests are the kind who will not scan anything, or there are only a few tables.

Choose an app if you want photos from every guest rather than every table, you want them at full resolution, and you want everyone to get the album rather than one person with a box of prints.

Or do both. A few physical cameras on the top tables for the object, and an app for the coverage. Plenty of couples land there, and it costs far less than a camera for every table. The sums are in what disposable cameras actually cost at a wedding.

Questions people ask

Do guests have to download an app? No. They scan a QR code. On an iPhone it opens instantly without installing anything, and on other phones it opens in the browser, where they can start shooting straight away.

Can I get the disposable camera look without film? Close to it. Pick the Vintage or black-and-white look when you create the event, and every photo in the album gets it. It will not fool someone who shoots film, but the album will look like one roll.

What if a guest's phone dies halfway through? Anything already taken stays on the phone, and in the Posy app it uploads once the phone is back on and connected.
