Ancient Light: From Cyanotypes to Tintypes
What keeps us coming back to the oldest photographic processes in a world obsessed with speed?
In the 1840s, photography was still alchemy. Every image was a physical reaction — light colliding with chemistry on a surface you could hold in your hands.
Processes like cyanotypes, tintypes, and gum bichromates weren’t just tools, they were rituals. Each step demanded patience, skill, and a willingness to surrender to chance.
Cyanotypes
Invented by Sir John Herschel in 1842, cyanotypes were initially used for copying engineering drawings — hence “blueprints.” Artists quickly embraced the process for its striking Prussian-blue tones, created by coating paper or fabric with iron salts and exposing it to UV light. The simplicity is deceptive: variations in sunlight, humidity, and even the brush strokes used to apply the chemicals all affect the final print.
Tintypes
Popular from the mid-19th century, tintypes involved creating a direct positive on a thin sheet of iron coated with a dark lacquer or enamel. Portable darkrooms meant tintype photographers could work on street corners, producing portraits within minutes. They were the Instagram pop-up studios of their day — except your “filter” was a lens cap and a steady hand with collodion.
Gum Bichromates
This process, favoured by Pictorialists at the turn of the 20th century, uses gum arabic, pigment, and potassium bichromate brushed onto paper. It’s labour-intensive and painterly, often requiring multiple layers and exposures to achieve a single print. Gum bichromates blur the line between photograph and fine art — every print is unique.
Why They Endure
In a digital age, revisiting these processes isn’t nostalgia for nostalgia’s sake. It’s about control through limitation. Ancient processes slow you down, demand commitment, and produce results you cannot fully predict or replicate. You work with the medium, not over it.
The Experience
Handling coated paper, watching an image emerge in sunlight or a developer tray, knowing it’s a one-off creation — these are sensations pixels can’t deliver. Each print is a physical artefact with texture, weight, and a sense of permanence.
💬 If you could spend a week mastering one ancient photographic process:
Which would you choose — cyanotype, tintype, gum bichromate, or something else?
What subject or theme would you explore with it?
Where would you want that work to be seen — gallery wall, portfolio, or personal archive?
