Taking Pictures With the Sun!

Mr. Brown and Squeaks return from a nature walk and explore the art of cyanotypes, a historical photographic process. Mr. Brown explains how to create a cyanotype using special paper, sunlight, and water, and delves into the science behind the process, highlighting the chemical reaction that forms Prussian blue. The video also covers the history of cyanotypes, mentioning Sir John Herschel and Anna Atkins, and provides a practical demonstration of making cyanotype art.
