How Corona Used a Billboard to Photograph the Sun

Quick answer: Corona’s Solargraph Series transformed a billboard into a working solargraph camera, using a modified Corona can as a pinhole device to capture the sun’s path over a 14-day period.

When the Billboard Becomes the Camera

Corona’s Solargraph Series turns outdoor advertising into something more than a message.

The billboard itself becomes a working photographic device.

A modified Corona can is installed on the structure and used as a pinhole camera to record the movement of the sun over a 14-day period.

A Simple Object With a New Purpose

The idea uses one of the brand’s most recognizable objects: the Corona can.

Instead of simply appearing in the advertising, the can becomes part of the technology behind the campaign.

This creates a direct connection between product, medium and creative execution.

Photography Powered by Time and Sunlight

The pinhole setup slowly captures the sun’s path through a long exposure.

There is no instant result.

The final image is created gradually as sunlight passes through the small aperture and leaves its trace over time.

The Reveal Becomes Part of the Experience

The campaign invites the public to return after two weeks to see what the billboard has captured.

That delayed reveal adds anticipation and gives the installation a second moment of attention.

The audience is not only shown an advertisement. They are invited to follow a process.

Why the Idea Works in OOH

The strongest part of the campaign is that the medium is not separate from the idea.

The billboard is both the advertising space and the instrument used to create the final visual.

That makes the execution feel native to outdoor rather than simply adapted to it.

What Brands Can Learn

  • The media format itself can become part of the creative idea.
  • Product objects can be reimagined as functional campaign tools.
  • Delayed reveals can create anticipation and repeat attention.
  • Simple technology can produce memorable physical experiences.
  • OOH becomes more powerful when the environment participates in the execution.

Final Reflection: Let the Medium Create the Message

Corona’s Solargraph Series is memorable because the billboard does not simply show the campaign.

It helps create it.

By turning a beer can and a billboard into a solar-powered camera, Corona makes sunlight, time and outdoor media part of the same idea.

Summary

Instead of using the billboard only as a display surface, Corona made the structure part of the creative process. The installation invites people to return after two weeks to see the long-exposure image created by sunlight itself.
