The slide projector and the family evening spent looking backwards

Everything below about the family slide show comes from what actually happens rather than from what is supposed to.

The format forced an audience

A transparency is nearly useless held up to a lamp and requires a projector, a screen and a darkened room to be seen properly. That made viewing photographs a scheduled group activity rather than a solitary one, which is a complete inversion of current practice.

The equipment cost meant one household member typically owned and operated it, giving them narrative control. A technical requirement produced a social form, and when the requirement vanished the form went with it.

Order and pace were fixed

Slides sat in a carousel or magazine in a decided sequence, advanced one at a time by the operator with commentary. That is a presentation rather than a browse, with an arc, a pace and someone responsible for both.

Look closer and scrolling through images individually removes sequence, commentary and the presence of an audience simultaneously. The much-mocked tedium of the slide evening was a consequence of somebody having genuinely composed something.

The joke about it is older than most people assume

Being trapped watching a neighbour's holiday slides was a stock comic situation for decades, which tells you the practice was widespread and widely resented. The resentment came from the loss of control: you could not skip, leave or look at your phone.

That absence of an exit is exactly what made it a shared experience rather than parallel individual ones. Every format with a captive audience gets satirised, and every satire is evidence of prevalence.

The material is deteriorating now

Colour transparency film fades over decades, at rates that depend heavily on the process used, storage temperature and humidity. Household storage in lofts and garages is close to the worst case for both temperature and moisture. Mould, vinegar syndrome in some film bases, and dye fading are all common in surviving collections.

Anyone with boxes of family slides has a time-limited digitisation problem rather than an indefinite one.

Scanning is achievable and tedious

Flatbed scanners with transparency units, dedicated film scanners and camera-based copying setups all work, at very different speeds and costs. Bulk services exist and vary considerably in quality, particularly in how they handle dust, colour and resolution.

The decision most people face is between doing it slowly themselves and paying for a result they cannot fully inspect. Either is better than the default, which is doing nothing until the dyes have gone.

The record here is thinner than it should be, and much of it was never written down.

The presentation format survived in an office

The word slide, the carousel metaphor and the idea of advancing through a fixed sequence moved directly into presentation software. The tedium migrated with remarkable fidelity, which suggests the problem was never the technology.

What did not migrate was the domestic setting, the darkness and the fact that everyone was in the same room. A format designed for family holidays now structures most of the world's corporate communication.

The takeaway

Looking at photographs used to require a dark room and other people. Now it requires neither, and the pictures are looked at alone.

The loss is small and cumulative, which is why it goes unremarked.
