Anna Atkins was a botanist and photographer whose familiarity with collecting plant specimens and making scientific illustrations led her to use John Herschel’s cyanotype process for the self-published Photographs of British Algae: Cyanotype Impressions beginning in 1843. She placed algae, ferns, and flowering plants directly on sensitized paper, recording outlines and translucent structures as white forms against Prussian blue. Her integration of fascicles, replacement plates, Latin names, and handwritten text into the photographic process makes the project an important early case in which botanical classification, camera-less photography, the photobook, and women’s participation in science intersect.
Atkins was trying to share the minute and intricate forms of algae without the errors introduced by hand drawing while working from William Harvey’s unillustrated taxonomic manual. Through the scientific network of her father, John George Children, she learned of John Herschel’s cyanotype process. By pressing the specimen itself against sensitized paper, she could obtain its outline and translucent structures as traces made by the plant.By using the specimen itself as the matrix and organizing the resulting images into a book that could be classified, corrected, and revised by replacement, she incorporated photography directly into the processes of botanical record keeping and publication.

Atkins’s work was closely tied to nineteenth-century British botany, specimen collecting, and scientific illustration. Her father, John George Children, was a natural scientist associated with the British Museum, and Atkins grew up familiar with collecting botanical specimens and producing scientific illustrations. The Natural History Museum explains that while women had limited access to professional scientific institutions at the time, botany was a comparatively accessible field, and that through her father Atkins encountered the new photographic processes of Talbot and John Herschel*1.
In the 1843 preface to Photographs of British Algae, Atkins explains that the difficulty of accurately drawing minute algae and confervae led her to adopt Herschel’s cyanotype process to obtain impressions of the plants themselves*2. The preface held by the British Library even notes that thicker specimens could prevent the glass from pressing closely enough against the paper, making a complete impression impossible in some cases*4. The same collection preserves the dedication to her father, the preface, plates, and correction instructions as separate sheets, making the book’s editorial process visible*8. Choosing cyanotype was a practical decision that addressed the inaccuracies of copying minute forms by hand by fixing an impression of the actual specimen on paper.
Cyanotype
Herschel’s cyanotype process, announced in 1842, uses paper coated with iron salts; after exposure to light and washing in water, the exposed areas turn Prussian blue. MoMA notes that Atkins was using the process to reproduce botanical specimens by the following year*5. Compared with contemporary silver-based photographic processes, its lower material cost and relatively simple processing also suited a project requiring many individual sheets*2. According to the Natural History Museum, the specimen was placed directly on dry sensitized paper, exposed for roughly ten to forty minutes, and washed in water. The resulting image preserves the outline where the specimen blocked the light and tonal variations in translucent areas as a contact trace close to actual size*1.
Photographs of British Algae
Photographs of British Algae: Cyanotype Impressions was distributed in parts from 1843 to 1853, and The Met identifies it as one of the earliest books illustrated with photographs*3. Atkins used specimens she collected herself as well as material received from other botanists, and followed the nomenclature of William Harvey’s Manual of British Algae*3. NYPL records show that, in addition to the botanical plates, title pages, tables of contents, and handwritten lettering were also reproduced in cyanotype; the project ultimately expanded to twelve parts in three volumes*6. Title pages, contents, Latin names, and plates were all made through the same cyanotype process, bringing the structure of the book itself into photographic production.
Fascicles, Replacement, and Correction
Surviving copies of British Algae differ in their selection and binding of individual sheets. NYPL explains that during the private distribution of the work from 1843 to 1853, Atkins added or replaced plates when better specimens became available*6. Atkins’s own correction instructions in the British Library specify plants to be moved to later volumes, the substitution of better impressions of the same species, and the withdrawal of misidentified plates*9. By comparing specimen quality, taxonomic names, and clarity of impression and updating sheets accordingly, the photographs functioned as illustrations revised along with botanical knowledge.
Specimen Placement and Composition
Direct contact printing preserves outlines with considerable precision, but it does not determine the composition automatically. NYPL notes that Atkins individually arranged, exposed, and processed more than four hundred specimens, treating scientific information and visual composition at the same time*10. As the V&A explains of camera-less photography, an object leaves a life-size trace on the sensitive surface, while the choice of what to place and where remains the maker’s decision*11.Pteris Rotundifolia (Jamaica) shows the plant’s finely divided leaves as white forms against blue, combining identifying information with the rhythm of negative space in a single sheet. MoMA describes Atkins as a figure who printed and published her own research photographically*12.
Sheets and Classification
A single cyanotype can be exhibited as an independent work, but it was originally part of a classified sequence. NYPL’s Ulva latissima belongs to the third volume, issued in September 1853, and its catalogue record links the Latin name, volume, place of publication, and Atkins’s self-publication*13. The Met likewise treats its copy of 154 sheets as a single album work, making the individual botanical images inseparable from the book’s larger indexical structure*3. The Rijksmuseum’s Lyngbya majuscula is also catalogued as a sheet from Photographs of British Algae, showing that each individual plant image belonged to the taxonomic structure of the book*23.
Ferns and Flowering Plants
After British Algae, Atkins extended cyanotype to ferns and flowering plants. Discussing her larger botanical images from around 1852–54, the V&A argues that while she retained Latin nomenclature, she gave increasing compositional attention to more familiar plants, shifting the emphasis from scientific record toward a more interpretive photograph*14. The conversion to a monochrome blue palette replaces the plant’s natural color, while organizing veins, stems, and overlapping petals into white and blue tonal relationships that make form easier to compare. In the Rijksmuseum’s Lycopodium Ceylon, a cyanotype from around 1854 records delicate stems and leaves as a contact image close to actual size, showing the same method applied to plant forms beyond algae*24.
Collaboration with Anne Dixon
Works from the 1850s begin to carry a joint attribution with Atkins’s childhood friend Anne Dixon. The Getty’s Uvena Novae Villiae, a large cyanotype from around 1854, is catalogued as a collaboration between Atkins and Dixon*15. The Getty notes that the two women produced numerous cyanotypes together for albums using both British and foreign plants*16. Atkins’s publications depended on networks of botanists exchanging specimens, her father’s scientific environment, Herschel’s process, and collaboration with Dixon. Within those networks, her role as editor becomes clear in the selection, sequencing, naming, and distribution of specimens.
Self-Publishing
At the center of Atkins’s work was small-scale self-publication for a circle of botanical colleagues. NYPL catalogues the place of publication as Halstead Place in Sevenoaks, Kent, and identifies Anna Atkins herself as the publisher*7. The Getty begins its exhibition on photobooks by historical women photographers with Atkins precisely because she was photographer, printer, editor, and distributor at once*17. In this self-publishing process, collecting specimens, sensitizing paper, exposure, washing, editing sheets, and distribution formed a continuous chain of production. The book opens with a dedication to her father, John George Children*26. Access through her father’s scientific network to the experiments of Herschel and Talbot, together with Atkins’s own experience collecting specimens and making illustrations, provided the conditions for the publication.
Scientific Record and Visual Form
Atkins’s sheets combine morphological record for taxonomy with compositional decisions about how a specimen occupies the page. Recent Getty research considers her cyanotypes through both Victorian scientific culture and aesthetic experiment, while also reassessing them against a period when women had limited access to professional institutions*18. The Met, while noting that artistic expression was not her primary purpose, explicitly recognizes the visual judgment with which she arranged specimens into elegant compositions*3. Taxonomic legibility and pictorial composition coexist on the same sheet.
Accuracy of Form
Because cyanotype records contours through direct contact, it is strong as a record of form, while replacing a plant’s natural color with Prussian blue. The V&A describes this tension as an image that is faithful to morphology as a contact print but non-naturalistic in color*14. The Getty’s account of Victorian plant collecting also shows that gathering and classifying algae and ferns was connected to social culture, placing Atkins’s sheets within a world broader than formal scientific research alone*19. Cyanotype replaced natural color with blue while preserving outline and morphology as comparable information.
Reassessment in Photographic History
Atkins’s work remained outside the center of photographic history for many years, but reassessment grew as surviving books and individual sheets entered museum and library collections. The Met presents sheets from British Algae around 1853 as independent photographs while also treating the book as a landmark in photographic history*20. MoMA places Atkins within the history of camera-less photography, connecting cyanotype to later experimental uses of the medium*21. NYPL’s Blue Prints exhibition reconsidered her work on a large scale through its application to botanical science, its publication history, and photographic production by a woman*22. The Rijksmuseum’s copy of the exhibition catalogue Sun Gardens follows Atkins from the algae book through botanical works made with Anne Dixon, placing her work within the expanding intersections of botany, photographic process, and collaboration*25.
Contact, Classification, and Editing
Atkins’s photographic process included placing a specimen on paper, exposing it to light, fixing the image through washing, adding a Latin name, distributing fascicles, and replacing incorrect sheets. The camera-less contact image preserved the specimen’s outline directly, while editing and distribution connected the image to taxonomic knowledge. In British Algae, the need to record plant morphology and the method of making and sharing a book were united in a single cyanotype process.
- William Henry Fox Talbot — A contemporary inventor who developed images on sensitized paper and the reproducibility of the paper negative-positive process. Atkins was familiar with Talbot's "photogenic drawing."
- Louis Daguerre — The daguerreotype produced a unique image on a silvered plate, offering a material contrast to Atkins's direct contact of specimens with paper.
- Julia Margaret Cameron — A woman photographer who established a distinctive authorship through portraiture in the 1860s, providing a different institutional position for women in early photography from Atkins's basis in science and publishing.
A foundational study of the bibliography, surviving copies, and production process of British Algae. Useful for understanding the work as a publication beyond the familiar view of it as a group of “blue plant photographs.”
