Over the past few months we’ve been asking you to help select everything from the photos in each chapter of the Unsplash Book, to the title and cover design.

And while we’ve had a guiding hand in each of these decisions, we felt that to make this a truly open source book, we needed to leave a portion of the pages entirely open to the people in the Unsplash community.

That’s why we’ve partnered with the team at Over—an awesome app that lets you create custom designs on your smartphone—to allow every single person in the Unsplash community the chance to have their work featured in the Unsplash Book.

Here’s how it works:

  1. Download Over from the App Store (we’ve got a limited number of promo codes for free downloads available on a first-come basis, so email us for yours).

  2. Choose a photo from the Unsplash collection in the Over app

  3. Create a design using your favorite quote about creativity (here are some great examples). Try to choose a short quote so it plays well over an image (example “Everyone is creative.”).

  4. Share your finished design on Twitter or Instagram using the hashtag #unsplashbook

One winner will be picked by the Over and Unsplash teams and announced on December 4th.

The winning design will be printed in the Unsplash Book and the designer will receive a part of the book’s profit split, a free copy of the book (value: $70), a package of goods, and get a shout out from the Over and Unsplash social accounts.

We believe that sharing your creativity is one of the greatest gifts any of us can give and can’t wait to see what you come up with.
