What is VQS? The Visual Quality Score, explained.

VQS is the Visual Quality Score, an objective, versioned standard for real-estate photography published by Standard Vision Lab. Every image is scored from 0 to 100 across the full set of measured checks, and each check and each image is marked PASS (90 and above), FLAG (70 to 89) or FAIL (69 and below). A certifiable set earns a live, verifiable badge automatically, with no panel and no opinion involved.

The standard exists so that image quality in property marketing can be measured rather than argued. This guide covers what VQS measures, how the scoring works, what happens at set level, and what the badge on a photographer's website actually guarantees. A longer walkthrough lives on the plain-English guide.

What VQS measures

Every image in a shoot runs through every measured check. The checks sit in six categories, with set-level consistency measured on top:

• EXP, exposure. Bright exposure, dark exposure and crushed shadows.
• WBL, white balance. Overall white balance, tint, and the white balance of window views.
• COL, colour. Colour cast, contrast, undersaturation, and the saturation of grass, greens and wood.
• GEO, geometry. Vertical and horizontal geometry.
• ART, artefacts. Noise, clipped windows, dark windows, window artefacts, ghosting and artificial texture in the blacks.
• SEM, semantic checks. Faults a buyer would notice, including camera reflections and visible cables.

Each check returns a measured value scored against published thresholds. Nothing in the score is a judgement call. The standard itself is versioned, and changes are published on the releases page, so a score always states which version of VQS it was measured against.

How the 0 to 100 score works

Every image receives a score from 0 to 100. Every check, and every image, carries one of three statuses:

• PASS: 90 and above.
• FLAG: 70 to 89.
• FAIL: 69 and below.

The runner that produces these numbers is deterministic. The same image produces the same score every time, byte-identical. That matters when a score is questioned: rerun the image and the answer does not change.

The set score is governed by the worst photo

A listing is only as good as its worst photo, and the SET score is built on that principle. The lowest-scoring image governs the set, and set-level gates apply on top. This means a set can FAIL despite a high composite. In one worked example, all 19 images passed individually, the mean was 98 and the lowest image scored 93, yet two soft frames tripped the focus gate. The set failed and no badge was issued.

The full logic is visible image by image in the sample report. Every measured value for every image is shown, not just the summary.

Why an objective standard exists

Real-estate photography has not had a shared definition of good. Briefs are written in adjectives, work is delivered to taste, and disputes come down to whose eye carries more weight. VQS replaces that with measurement. A number computed the same way for everyone can be written into a brief, checked on delivery and verified by a third party. Measured, not opined.

For photographers, the standard turns quality into something you can prove rather than assert. For agency marketing managers, it turns a vague expectation into an acceptance criterion.

Who certifies, and how

Certification is automatic and comes from Standard Vision Lab's canonical runner. There is no panel and no reviewer. A run works like this:

1. Submit a set of 12 to 20 original JPEGs from a daytime shoot. Twilight and dusk shoots arrive with v2 of the standard.
2. Every image is fingerprinted with SHA-256. Duplicates within the set, or against earlier runs, are removed automatically, so every run measures fresh work.
3. The runner measures every check on every image and computes the composite.
4. A certifiable composite earns its tier badge automatically, and the full annotated report becomes a permanent part of the certification record.

You can run a shoot through the demo to see the process end to end.

What the badge means

The tier is set by the composite score:

• Platinum: 100.
• Certified: 90 to 99.
• Provisional: 70 to 89.
• No mark below 70, and a failing set never certifies regardless of its composite.

The badge is a live embeddable widget served by SVL, added with one line of HTML. Anyone can click through to the public verification register and see the tier, the composite, the covered files and the dates. The mark expires 12 months after the last certified run, and an expired, suspended or revoked mark visibly says so wherever it is embedded. A badge cannot quietly go stale.

Every certificate also opens the full annotated report: every image, every measured value.

What certification costs

There are two ways in:

• US$9.99 per month. One measurement run included each month. The mark stays live while you are subscribed, with a recertification run required at least every 12 months.
• US$129 single run. The badge is valid for 12 months.

Reports are permanent parts of the certification record either way.

Where to start

Read the plain-English guide, look at the sample report, then run a shoot. If you are checking a badge someone else is displaying, the register is public.
