What a painter can and cannot read out of the photograph you send

Room Text, at the Entrance

The Corkboard

Pinned lowest on the corkboard, at knee height where nobody crouches to look, is a photograph with its filename printed along the border in a typeface no camera has ever produced: IMG-20260714-WA0007.

Somebody has folded the corner back once, the way you dog-ear a page you don't intend to return to.

The face is a good face. It has travelled badly.

I come here before the painters do, when the room still smells of whatever they use on the linoleum and the radiator ticks the way old radiators tick — protesting the cold rather than addressing it. The board runs the length of one wall. Four rows, red-headed map pins. I walk it left to right the way you'd walk a hang.

A wedding photograph, glossy, catching the strip light. A dog mid-shake, ears in two places at once, water frozen off the coat by a fast shutter — that one will paint, I think, and move on. A child on a swing shot from the mother's full standing height: the crown of the head enormous, the chin a rumour. A studio headshot with the flat shadowless light of an office corridor, every pore legible and every plane of the face erased in the same gesture, which is the trick flash performs and never gets blamed for.

Then the WhatsApp one again, because the board loops and I've walked the whole thing without meaning to.

Fifty-Three Billion a Day

Somewhere around one and a half billion photographs were taken while I was in that room. Not there — worldwide.

Current estimates put 2026 at 1.95 trillion photographs: about 5.3 billion a day, 61,800 every second, ninety-four per cent of them from phones, against an accumulated stock of some fourteen trillion images already in existence.

Almost none of them will ever be printed. A handful, per household, per generation, become the photograph — the one that gets forwarded, and pinned to a board like this, and painted.

Is My Phone Good Enough for This?

Nearly always. The object in your pocket outperforms the object it's about to become.

Twelve megapixels is 4,032 pixels one way and 3,024 the other, and a painted face at any size a studio sells needs a fraction of that — arriving intact at the face itself, not at the frame around it.

The camera was never the problem. What happened to the file on the way here usually was.

The number, from an unglamorous place

ISO/IEC 19794-5, the biometric standard behind passport and border-control photographs, sets the minimum inter-eye distance at 90 pixels, preferring 120 — the point below which a machine can no longer reliably tell one face from another.

A painter needs considerably more than a border guard's algorithm, because a painter is rendering the specific rather than matching against a database.

But the standard is useful as a floor under the floor: if your photograph can't clear a passport gate, it certainly can't clear a canvas.

What Sixteen Per Cent Looks Like

I go back to the low one, the folded corner, and crouch to look properly. Knees, complaining.

Held at arm's length it reads as a face — unremarkable, forgivable. Closer, the failure acquires a texture: soft rectangular blocks where a cheek should carry gradient, laid down not by the camera but by a piece of software somewhere between a phone and a friend, deciding that a hundred kilobytes was plenty.

Eight-by-eight blocks. The signature of a JPEG re-encoded past its own tolerance — and once you've seen it in one photograph you see it in every photograph, the way you can't unsee a repointed wall.

What left the sensor as twelve million points of information arrived here as roughly two.

Sixteen per cent of a face. And everyone involved believed they had sent a photograph.

Why does the app I use for everything do this?

Because it was built to move a conversation, not preserve an archive.

It takes the long edge down to around 1,600 pixels and re-compresses what remains at something like sixty to seventy-five per cent quality — cheerfully, without asking.

Sent as a document instead, the same file arrives untouched, the way a hand-carried letter arrives unfranked.

Instagram is worse and more honest about it: what you can pull back down is 1,080 pixels wide, about seven per cent of the original, which is sufficient for a screen and nothing else.

A School Photograph

There was a school photograph once. Mine.

Against a mottled blue backdrop meant to suggest sky, suggesting instead a bruise at the yellow stage. The photographer stood on a box. I was seven, or eight — near enough that the arithmetic doesn't matter — and for years afterward that was the face I understood myself to have: foreshortened, chin-first, the eyes migrated upward under a forehead the lens had decided to enlarge.

It took a later photograph, taken by someone standing at a normal distance with nothing under them, to establish that the forehead had been lying.

So I have a certain patience with the selfies on this board.

Held at arm's length, twelve inches, the nose arriving about a third larger than the nose actually is. There's a citation for it now — Paskhover at Rutgers and Fried at Stanford, in JAMA Facial Plastic Surgery, 2018, modelling the thing properly: at twelve inches the nasal base photographs some 30% wider and the tip about 7% wider than the same nose at five feet.

The seven-year-old on the box could have told them for nothing.

The Two Lenses, Six Millimetres Apart

The phone in your hand is a 24-to-26-millimetre lens, in the terms photographers use — a wide lens, the kind you'd point at a room.

The telephoto beside it is 77, or 100, or 120 millimetres depending on the year of manufacture, which lands it squarely in the range portraitists have used since portraiture went industrial: 85 to 135 millimetres, chosen because it renders a face at roughly the proportions the eye reports at conversational distance.

Both lenses are on the same object, six millimetres apart.

And almost nobody uses the second one for a face.

Why does the painting look wrong when the photo looked sharp?

Because sharpness and distance are different quantities, and the eye conflates them.

A photograph can resolve every eyelash and still be lying about where the camera stood. A painter working faithfully from what's in front of them renders the lie with exactly the care they'd give the truth.

Nothing downstream corrects a decision made at the shutter. Not resolution. Not the elite-artist upgrade. Not an unlimited revision policy.

Sharpness this board has in quantity. Distance it does not — and the two rarely arrive in the same file, which is the whole difficulty of the room, tucked into a fact nobody asked me to state plainly:

The highest-resolution photograph on this wall is a face shot from twelve inches, and it is the one a painter should be handed last, if at all.

Three Questions Asked at the Desk

Is a phone photo good enough for an oil painting?

Yes, in almost every case. A standard 12 MP phone camera produces 4,032 × 3,024 pixels — about twice what a hand-painted portrait needs at any ordinary catalogue size, and roughly one-sixth of what a printed reproduction of the same size would need.

Two conditions attach. Send the original file, not a messaging-app copy. And shoot with the telephoto lens from four to eight feet back, not the main wide lens up close.

Why does my sharp, high-resolution selfie produce a poor likeness?

Because resolution and perspective are independent. At twelve inches the nasal base photographs roughly 30% wider and the nasal tip about 7% wider than at five feet. The painter reproduces that faithfully, because to the painter it is not an error — it is the reference.

Perspective is fixed at the moment of exposure. Cropping afterwards changes the framing, never the proportions. Step back and zoom in rather than stepping closer.

How much resolution do I actually need — and how do I check it?

Ignore megapixels and measure the face. Crop the file down to head-only, save it, and read the pixel height in any image viewer's info panel.

• Under 200 px — unusable; features are guesses.
• 200–500 px — a generalised likeness, viable up to about 12 × 16 in (30.5 × 40.6 cm).
• 500–1,000 px — reliable to about 20 × 24 in (50.8 × 61 cm).
• 1,000–2,000 px — full detail at any catalogue size.
• Over 2,000 px — no further benefit.

Wall Label: Minimums for a Hand-Painted Portrait Reference

What Each Delivery Route Leaves of a 12 MP Original

Resolution By Finished Painting Size

Deliberately not print-DPI figures. The right-hand column shows what a giclée of the same size would demand, so the gap is legible.

Past roughly 30 × 40 in (76.2 × 101.6 cm), the print requirement exceeds any consumer camera while the painting requirement stays inside a good phone file.

Large hand-painted work is the format that tolerates ordinary photographs. That is genuinely counter-intuitive and it is the single most useful thing I learned writing this.

Head to Head: Who Tells You Any of This Before You Pay

Notice the split down the middle of that table. Half these vendors won't take your photograph at all — they reproduce catalogue works, where the source file is their problem and not yours. Which is a legitimate and much simpler product, and if what you want is a Monet rather than your grandmother, it removes this entire article from your life.

And among those who do take your photo, the thing to look for isn't price. It's the approval step. A mock-up before painting, or a photograph of the finished canvas before it ships, is the only mechanism that catches a bad reference before it becomes a bad painting.

Nobody in this trade publishes a face-pixel threshold. I checked. So until somebody does, the wall label above is the check, and you have to run it yourself, before you upload.

Leaving

I straighten up. The knees have a position on the crouching.

Outside the small high window the light hasn't shifted in an hour — flat, undecided grey, less a promise of rain than its standing possibility — and on the board the folded photograph is still sixteen per cent of itself, still waiting to become somebody's grandmother in oil.
