Photography
Silver, platinum, cyanotype, and dye — the chemistry of captured light.
14 eras
Daguerreotype
1839–1860The first practical photograph — a mirror that remembers. Silver-plated copper yielding ghostly, shimmering images.
Calotype / Salt Print
1841–1860Paper negatives yielding soft, warm prints. Talbot's invention — the ancestor of all modern photography.
Wet Collodion / Ambrotype
1851–1880Glass plate negatives coated with collodion — sharp, detailed, but must be exposed while still wet.
Albumen Print
1850–1900Egg white as binder — the dominant photographic print of the 19th century. Billions of eggs cracked for photography.
Cyanotype
1842–presentPrussian blue photography — iron-based process producing vivid blue images. Anna Atkins used it for the first photo-illustrated book.
Carbon Print
1855–1940Pigmented gelatin giving permanent, velvety prints. The most archival photographic process — immune to fading.
Platinum / Palladium Print
1873–presentThe most beautiful photographic prints — noble metals embedded in paper fiber. Warm greys with infinite subtlety.
Autochrome Lumière
1907–1935The first practical color photography — potato starch grains dyed red, green, blue as a pointillist color filter.
Kodachrome
1935–2010The gold standard of color transparency film. Warm, saturated, stable — 'they give us those nice bright colors' (Paul Simon).
Ektachrome
1946–presentKodak's cooler, bluer transparency film. Where Kodachrome was warm and golden, Ektachrome was crisp and clean.
Fujichrome Velvia
1990–presentThe landscape photographer's film — hyper-saturated greens and blues that made nature look more vivid than nature.
Kodak Portra
1998–presentThe portrait photographer's film — fine grain, natural flesh tones, soft pastels. Designed for skin.
Polaroid / Instant Film
1948–presentSelf-developing photographs — peel apart or integral. Unique chemical palette, imperfect, irreproducible. Each print one of a kind.
Infrared Film
1910–presentSeeing beyond visible light — foliage glows white, skies go black, skin becomes translucent. An alien world recorded on film.
