International photography challenge

12 by 12 was a year-long series of monthly photo challenges set by renowned photographers. Each brief invited group members to respond creatively and share their interpretations on social media.


I started 12 by 12 to push my own creativity and build a photographic community. I led on strategy, branding, design, marketing, copywriting and community management. Bringing together and guiding a team to deliver the project. Thousands of images were submitted, and the work was featured by the BBC and the Royal Photographic Society.

Behind the challenges


The project aimed to stretch members creatively, encouraging experimentation in both approach and aesthetics. Community was a core element of 12 by 12, and the group’s support played a big role in keeping momentum and motivation throughout the year.


Photo challenges are nothing new, but what set this project apart were the thought-provoking briefs, designed to push members beyond their comfort zones. The team and I worked hard to ensure challenge-setters came from a wide range of countries and photographic disciplines.


The project offered an insight into how respected photographers approach their work, as the challenges often reflected their personal practice. To build on this, I held interviews with challenge-setters, driven by questions from the group.

Member reflections

member's Book


12 by 12 was the final instalment in a three-year series of photo-challenge projects that attracted some of the world’s most respected contemporary photographers, including Edward Burtynsky, Carolyn Drake, Nadav Kander, Steve McCurry, Terry O’Neill, Martin Parr and Alec Soth.


At the end of each year, the team and I curated a shortlist of standout member submissions. I designed and edited a book to showcase a small selection of the 3,500+ images submitted, capturing the diversity of styles, formats and approaches that emerged throughout the project. A percentage of profits from the book went to the charity PhotoVoice.

Challenge setters


Over the course of three years the project featured briefs from some of the world’s most respected contemporary photographers.


At the outset, we couldn’t have imagined attracting such a high calibre of international contributors, or that the standard of responses would be so consistently inspiring.

Take a route you’re familiar with but have never photographed along and photograph someone or something every 100 or so steps.
Vanessa Winship

Find a place where you live where history made its mark. Allow yourself to breathe, feel, contemplate and react with a photograph.
Laura El-Tantawy

Build something with the intention of photographing it. After you have photographed it disassemble whatever it is that you created.
Dan Winters

Photograph the interior of a building without going inside. Choose a place you’ve never been in before.

We have tested and tasted too much, lover – through a chink too wide there comes in no wonder.
Eamonn Doyle

Take a photograph that will embarrass you and make your audience uncomfortable.
Erik Kessels

Take what you believe will be the final series of photographs before you die.
Nick Brandt

Photograph something that you have had in your mind for years and you just can’t let go.

Don’t see photographs as an end result, rather as a source.
Anouk Kruithof

Try to tell the truth by taking photographs that lie about it.
