Pasadena Heritage invites the public to step back into the Victorian era for a hands-on exploration of the “blueprints of nature.” This immersive heritage workshop celebrates the groundbreaking work of Anna Atkins (1799–1871), the English botanist and photographer who transformed scientific documentation through art and innovation. Atkins produced the first book illustrated entirely with photographs, Photographs of British Algae: Cyanotype Impressions (1843), using a revolutionary cameraless printing process that continues to captivate audiences today.

What Participants Will Experience

The History
Guests will discover how Atkins used the cyanotype process—developed in 1842 by her family friend Sir John Herschel—to carefully document delicate botanical specimens such as ferns and algae. Her work beautifully bridged science, art, and early photography.

The Science
The workshop explores the chemistry behind the iconic “sun print.” Paper treated with iron salts reacts to ultraviolet light, producing the rich Prussian blue tones that define cyanotypes. This elegant process reveals the powerful intersection of natural light and scientific discovery.

The Craft
Participants will create their own botanical cyanotype using locally gathered plant materials. By arranging specimens on light-sensitive paper and harnessing the power of sunlight, each guest will produce an archival-quality print to take home—experiencing the timeless practice of preserving nature through handmade heritage, just as Atkins did nearly two centuries ago.

Ideal for artists, nature lovers, history enthusiasts, and anyone curious about early photography, this workshop offers a thoughtful opportunity to slow down, observe closely, and create something beautiful rooted in the past.
