# A photo of a photo is how family history travels now

> Most old family photographs don't arrive as a scan. They arrive as a phone photo of a screen, complete with moiré and a window reflection — and that's fine.

A photograph of a photograph. The picture inside the picture is faded and propped a little crooked on
the monitor it's leaning against. A fine web of interference lines ripples across all of it, a window
is reflected somewhere in the top corner, and a sliver of black screen bezel runs along one edge.

This, statistically, is how the photo actually got to you.

## Why does the picture look like it's shimmering?

Because two grids are overlapping and slightly out of step with each other. A monitor displays an
image as a fine grid of pixels; a phone camera captures it as a different, unrelated grid of its own.
Photograph one grid through the other at a small mismatch in scale or angle and the two interfere,
producing a third, larger rippling pattern that doesn't exist on the screen or in the camera on its
own — it only exists in the meeting between them. That's moiré, and it shows up any time you point a
camera at a screen.

## Why is there a reflection sitting in the corner?

Because a monitor is glass, and glass photographs whatever light happens to be behind whoever's taking
the picture. A kitchen window is in the reflection because the laptop was open on a kitchen table when
somebody leaned over it with their phone. It's not a flaw introduced by the process — it's a fairly
precise record of the room the rephotographing happened in.

## Should you track down a cleaner scan instead?

If one exists, it's usually worth using. A proper scan removes both the moiré and the reflection, and
there's no argument for artefacts over a clean source when a clean source is actually sitting in a
drawer somewhere. Most of the time, though, nobody has one — the original went missing decades ago, or
it lives in a relative's house three states away, and this phone photo of a screen is the only copy
that's ever made it into a group chat. Printing it as it actually arrived, moiré and all, is the honest
option when a scan isn't coming.

### Isn't printing the artefacts just settling for a worse photo?

Not really — the ripple and the reflection are evidence of exactly how the photo reached you, not
damage to apologise for. A photograph that circulated through six phones and a shared album link has a
distribution history the same way an old print has a wallet crease, and printing it plainly is closer
to the truth than sourcing a suspiciously clean copy would be.

## Does the resolution actually hold up at that point?

Often, yes, though it's worth checking rather than assuming. A photo taken of a screen carries less
detail than a direct scan of the original print would, but for a chest-sized print that's frequently
still enough — the question of exactly how much resolution a given size needs is answered properly in
[the piece on images that are genuinely too small to print](/stories/ai-image-too-small-to-print).

## Is there anything to clear before printing it?

Not if it's your own family's photograph, rephotographed by you or somebody in your family off your own
screen. Nothing about the method of capture changes who the underlying picture belongs to. If you're
working out how to actually get that phone photo into a usable file for a print, that part is covered
separately in
[the piece on supplying a usable image](/stories/pet-photo-on-a-shirt).

## Does this only apply to old family photographs?

No — it applies to anything whose only surviving copy is itself a photo of a screen, which by now
covers a lot more than old prints. A text message screenshot, a video call still, a photo somebody
already reposted from somewhere else: the moiré and the reflected window are simply what a picture
looks like once it's been through a phone camera one extra time. It's becoming the ordinary condition
of a photograph, not an exception to how photographs normally look.

## Does it print well?

Yes, treated the right way. The moiré itself is fine, irregular texture and will fill in at print size
if left as-is, so it works better simplified into a deliberate, slightly exaggerated ripple rather than
reproduced pixel for pixel. The window reflection is close to a flat bright shape already, which
survives fabric well, and the sliver of screen bezel makes a genuine, natural edge to crop against
rather than an arbitrary box around the artwork.

Off-white, pale grey and a warm cream all let the photograph's own colours carry the print. Two or
three inks is usually enough — the underlying photograph reduced to its own tones, the moiré and the
reflection picked out as separate flat layers on top.

## How do I get one made?

Describe the photo at [JustOG](/) — how strong the moiré is, where the reflection sits, how faded the
photograph inside it looks. Pick a direction, drag the crop frame, see it composited on the real
garment, and it's made to order and shipped.

Designs other people have published are in the [shop](/shop).

Somewhere there's a slightly better photo of this same photo, and nobody's found it yet.
