Four Corners Protocol
Transparency. Authenticity. Credibility. Authorship.
A protocol for the 200th year of photography.

The Crisis
Nobody believes photographs anymore.
Images are manipulated, simulated by AI, stripped of context, and circulated without attribution. "The camera never lies" is dead. The head of Instagram cameras said his grandchildren won't believe any photograph of him actually happened. The Washington Post dissolved its entire photo staff. We are drowning in images and starving for truth.
The question is no longer "Is this photo real?" — it's "Who made this, why, and can I trust them?"
Three Ideas for Ensuring Photographic Credibility
1
Treat journalistic photography as a quotation from appearances
The frame acts like quotation marks. What's inside cannot be modified without signaling the change.
2
Treat the photographer as an author
Depend on the integrity of the person, not the camera. The same way we trust a writer.
3
Allow for more context
A photo is taken in a fractional second, but the story is infinitely deeper. Give the reader a way in.
The Paradigm Shift
Today
People are viewers of images — passive consumers with no way to evaluate what they're seeing.
With Four Corners
Four Corners turns viewers into readers of images — active participants who can explore the depth behind every photograph.
The expectation transforms: I want the data layer. I want to explore what I'm looking at. And when it's not there, that's the outlier.
What Is Four Corners?
Four Corners is an open protocol — not a platform — for embedding contextual metadata directly with images.
Each image has four interactive corners, each holding a different layer of meaning. Click a corner, and the image opens up.

The protocol can be adopted by any platform — Flickr, Instagram, AP, Reuters — without requiring a centralized system. We build the standard. Platforms integrate it.
The Four Corners
Upper Left — Related Imagery
Photos from before and after. Video of the same event. Behind the scenes. Images from the same location or of the same person. The single photograph becomes part of a larger visual narrative.
Upper Right — Links
Link to the photographer's website. Links to the accompanying story or video. Historical information. Other contextualizing resources. The more people link to your work here, the more credible it becomes.
Lower Left — Backstory
The photographer's contextualization. The subject's point of view. A witness or journalist's account. Related audio. The human story behind the fractional second.
Lower Right — Authorship
Caption and credit. Copyright or Creative Commons. The photographer's code of ethics. Link to agency or organization code of ethics. Website, bio, and contact.
Authorship First, Not Forensics First
Four Corners is fundamentally different from approaches like C2PA (the Content Authenticity Initiative).
C2PA Approach
C2PA tracks every technical change made to an image on a cryptographic ledger — what Photoshop filter was applied, what crop was made. It asks the computer to vouch for the image.
Four Corners Approach
Four Corners asks the human to vouch for the image. Who are you? What did you witness? What's your code of ethics? What else should I know?
GPS coordinates, camera data, and timestamps can bolster authorship — but they are always secondary to the human layer. This is not an FBI tool. It's an authorship tool.
The NF Standard — Nonfiction Photography
If we can label certain photographs as NF (Nonfiction) — meaning an actual, largely unretouched photo that is not deceptively staged — we solve multiple problems at once.
Actual
The scene really happened in front of the camera.
Largely Unretouched
Standard processing is fine; substantive manipulation is not.
Not Deceptively Staged
The photographer didn't fabricate the scene to mislead.
Other images can be labeled however the creator chooses. NF is specifically for images that witness in a credible way. One clear standard. Opt-in. No spectrum to police.
Codes of Ethics — Choose Your Own
The protocol includes a library of codes of ethics that photographers can adopt — or they can write their own.
Photojournalist
My photographs respect the visible facts of the situations I depict. I do not add or subtract elements.
Citizen Journalist
I do not stage events or manipulate situations for the camera.
Fine Art Photographer
I may alter my images in pursuit of my own artistic vision.
Associated Press
I abide by AP's ethics code.
UNICEF
I do not show the faces of children who are HIV-positive or who have been child soldiers.
Wildlife Photographer
All my photographs depict animals in the wild unless otherwise specified.
Or make your own.
Who Is This For?
Three paths into the protocol — three different relationships to the image.
The Citizen
The person in Minneapolis with a phone. Documenting what matters in real time. No press pass, no institutional backing, no credibility infrastructure — just a camera and a conscience.
Their images may be the difference between accountability and impunity. Four Corners gives them a fast, lightweight way to establish context and build trust. Voice input. Minimal fields. Maximum impact.

As others link to and endorse their work through the protocol, their credibility grows organically — no license required.
The Non-Fiction Photographer
The professional who commits to the NF standard. Photojournalists, documentary photographers, independent visual reporters — anyone who signs a code of ethics and stakes their reputation on what's inside the frame.
Four Corners gives them the infrastructure that institutions used to provide. Authorship, provenance, ethical accountability — portable across any platform, not dependent on a single employer.
When the Washington Post fires its photographers, the protocol travels with the photographer.
The Archivist
Institutions preserving decades of visual history. News archives digitizing film. Libraries contextualizing collections. Open-source intelligence researchers triangulating evidence.
For the archivist, the four corners are a way to preserve and enrich context that would otherwise be lost — who took this, when, why, what else was happening. The protocol becomes a preservation standard, not just a publishing standard.
Every image in an archive is a witness. Four Corners makes sure the testimony survives.
How It Works — The Generator
The generator is the heart of the protocol — where photographers create their four corners metadata.
Citizen Journalist
Gets a fast, voice-driven flow.
Non-Fiction Photographer
Gets a robust editorial workspace.
Archivist
Gets batch tools and provenance fields.

But every path produces the same interoperable metadata. One protocol. Many entry points.
What the Reader Sees
When a reader encounters a Four Corners image, the four corners are indicated by subtle markers at each corner of the photograph.
1
Click a corner
The image opens up.
2
Context unfolds
Related photographs appear. The backstory unfolds. Links to deeper context emerge.
3
Identity revealed
The photographer's identity, ethics, and intent become visible.
The image transforms from a flat surface into an explorable experience. Not intimidating — inviting. Not forensic — human.
Credibility That Grows
The upper right corner — Links — becomes a credibility signal over time.
When professionals link their work to a citizen journalist's image, that endorsement is visible. When 74 people connect their own reporting to yours, the protocol reflects it.
Institutions can badge their members — ICP alumni, Missouri graduates, AP staff — creating networks of accountability. If a member acts in bad faith, the badge can be revoked.
The Core Principle
Credibility is not granted by a single authority. It emerges from the network.
The Opportunity
AI-generated imagery is flooding every platform. Trust in visual media is at an all-time low. Major newsrooms are collapsing. Citizen journalists are producing the most consequential images of our time with no infrastructure to support them.
Four Corners is that protocol.
A Protocol, Not a Platform
Four Corners is designed to be adopted, not owned.
Management overhead is near zero. The goal is a credible, transparent standard for visual media that any organization can implement. Open source where it makes sense. Licensable where it needs to be.
Writing with Light sets the standard. The world adopts it.
