THESE impressive images include some of the first photographs of nature, taken from Unearthed: Photography鈥檚 Roots, an exhibition tracing the history of photography from the 1840s to the 21st century through depictions of plants and botany. The exhibition is showing at Dulwich Picture Gallery, London, until 30 August.

The image听above shows a vase of poppies, taken by Richard Learoyd in 2019 using an ancient device called a camera obscura. This is created by making a tiny hole in one wall of a small, dark room, which acts as a lens and projects an image of whatever is outside onto the wall opposite the hole.

The above image shows a species of brown algae called Dictyota dichotoma, or forkweed. It is a cyanotype, a photographic print in which paper coated with iron compounds creates a rich blue image when exposed to light, and it was taken by Victorian botanist and photographer Anna Atkins. She produced more than 400 images of algae between 1843 and 1853, and is thought to have been the first person to illustrate a book with photographic images.

Charles Jones鈥檚 shot above of a stack of broccoli was achieved using gelatin silver printing, a technique developed in the 19th century. Jones used the same method to capture the image of a bean pod below.

Below it is a shot of some peas by artist Gyula Holics, who also used gelatin silver printing.
