The leaf is not the ink

A cyanotype can look like a plant has printed itself. The arrangement asks more of its maker than that.

Imagine two effectively opaque leaves held flat against sensitised paper, one partly covering the other. In a drawing I could give each its own outline, even inventing the hidden edge. In this imagined cyanotype, the leaves do something less accommodating: they get in the light’s way. Real leaves can transmit light; here I am choosing the simpler case of a pair that blocks it.

The familiar white-on-blue plant print is made with light-sensitive iron chemistry. Kew describes the sequence: an object lies on treated paper, ultraviolet light exposes the uncovered areas, and a water wash completes the process. An opaque object protects the paper beneath it. The pale shape is not green pigment transferred from the leaf. The leaf is a temporary mask.

That difference changes where I would put my attention. The subject of the picture seems to be the leaf, yet the blue around it is doing much of the visible announcing. I would normally call that area the background. Here it is also the part of the sheet that was allowed to meet the light.

The V&A dates John Herschel’s cyanotype process to 1842. Its account includes plant specimens, drawings and photographic negatives among the things that can be placed over the treated paper. So a cyanotype need not be a leaf silhouette, and the process is not defined by the absence of a camera from every earlier stage. A photographic negative can bring an image made elsewhere to this particular encounter with light.

For the two leaves in our imagined composition, though, there is no earlier camera view. Their arrangement is the image-making decision. Move them apart and the blue can enter between them. Let them overlap and the protected areas join. The resulting white region may no longer tell a viewer exactly where one leaf ended and the other began. The plants have not become less distinct; the arrangement has made some of that distinction unavailable to this print.

I like this as a small objection to the phrase nature printing itself. Nature supplies the specimens, but someone has chosen the pair, their orientation, their overlap and the edges of the sheet. A direct physical process can still be composed. Removing the draughtsperson’s pencil does not remove the maker’s decisions.

Kew’s account of Anna Atkins places her botanical cyanotypes at an early meeting of photography and scientific illustration. Her Photographs of British Algae: Cyanotype Impressions began in 1843. I find the word impressions useful here. Contact sounds like a way to dispense with interpretation, but contact still has to happen in an arrangement. A specimen does not decide where the page begins.

Consider the margin. Put a stem close to the edge and it can seem to continue beyond the sheet; turn it inward and the same length can hold the composition together. Neither choice requires adding anything to the plant. The intervention is a relationship, established between something found and a boundary chosen. It is a modest kind of authorship, but not an absent one.

There is a practical generosity in keeping the specimens movable before the exposure. A small rotation can be tried without erasing a line. That suggests a different question from how faithfully I could draw the leaf: what changes if I move it? I would begin with the gap between the stems, widen it, narrow it, and decide which arrangement deserves to become fixed.

The leaves can be lifted away. The arrangement cannot be lifted out of the picture. That is the maker’s contribution I would look for first: not a signature in the corner, but the narrow blue passage they left between two stems.
