Natural view perception for phone cameras

Your camera captures the view. Sjona restores how you saw it.

Wide-angle photos make distant objects smaller than you saw them. Sjona brings them back to the size you saw and keeps the whole wide view. From one photo, on the phone.

Sjón (Icelandic) — sight, vision. Sjón er sögu ríkari — seeing is believing.

Move across the photo to compare. The distant ridge comes back to the size it looked on the spot; the rocks at the photographer’s feet keep their shape.
The problem

Wide photos shrink what we saw.

The eye sees sharply across about 40–60°, the field of a ~50 mm “normal” lens. Phones shoot wider, at 13–24 mm, to fit the whole scene, and distant objects shrink.

Barrel distortion is a separate defect, and manufacturers already correct it. This is the geometry of a wide view: a full-frame camera with a wide lens shrinks the mountain exactly like a phone.

Photographers step back and zoom in, so near and far keep their proportions. Often there is no room to step back, and no camera fixes it afterwards.

In their own words

People have noticed it for years.

Photography forums, blogs, Reddit and a newspaper describe the same thing, long before anyone gave the problem a name.

“How can something so massive… look so tiny and unimpressive in a photo?”

“Why do photographs of beautiful scenery never do it justice?”

“What ends up on my camera or phone isn’t the spectacular sight I witnessed with my two eyes.”

“I personally do not think pics do any ranges justice.”

“Some of my photos fail to show the true depth of the features.”

“Why does the moon look smaller on photos than it does in real life?”

How we see

The brain scales distant objects up. A flat photo loses that.

  1. A photo is physically correct. It records light from one point. The distant mountain really takes up a small part of the frame.
  2. In the real scene we judge sizes. The eye moves from object to object, and the brain assembles the picture piece by piece, scaling the distant mountain up. This is size constancy.
  3. A flat photo loses that cue. On a screen everything is at the same distance, so the mountain is seen at its pixel size: tiny.

Sjona applies the brain’s correction to the photo: distant objects at the size we saw, the wide view kept.

Results

Real phone photos, processed by Sjona.

Each pair shows the original phone photo and the same photo processed by Sjona. The mountain photos on this page were taken by Andrey, our technical co-founder, on his trips.

The cathedral is as large as it looked. Sjona brings the whole scene closer, the background the most; the person grows a little too. Enlarging has a cost: the frame edges stretch sideways.

The mountains are as high as they looked. A tourist camp below a mountain range. In the original the peaks look like hills. Sjona keeps the geometry of the frame almost unchanged and brings the mountains closer. The numbered markers point to the same spots in both photos.
The next frontier

Phone cameras compete on light and colour. Depth is next.

Each step so far works with light, colour or pixels. No camera today, phone or professional, restores how near and far relate in the frame.

  1. 2010

    HDR

    Several exposures merged for light and shadow

  2. 2016

    Portrait mode

    Depth is estimated and used to blur the background

  3. 2018

    Night mode

    Multi-frame noise reduction in low light

  4. 2024

    Generative edit

    AI moves, resizes and removes objects

  5. Next

    Depth and perspective

    Depth rebuilds how near and far relate, as the eye saw it

First mass-market launches: HDR (iPhone, 2010) · Portrait mode (iPhone 7 Plus, 2016) · Night Sight (Pixel 3, 2018) · Generative Edit (Galaxy S24, 2024).

Status and roadmap

Working alpha today. Public launch in 2027.

Sjona already runs as a working alpha app: one photo in, the corrected photo out, on the phone, with no cloud.

  1. 01

    Consumer app

    Public launch on iOS and Android in 2027. Real usage on thousands of real scenes proves demand.

  2. 02

    Phone-maker prototype

    A version calibrated for flagship phone cameras, ready for phone makers.

  3. 03

    In the native camera

    Sjona as a native Camera or Gallery feature, under a licence, a development contract or a deeper partnership.

For phone makers

A camera feature reaches every owner of the phone by default. We are looking for a first phone-maker partner to bring Sjona into the native camera.
