Tintype / Wet Plate

Description

The wet-plate collodion process was invented in 1851 and was the dominant photographic process from roughly 1855 to 1880, before gelatin dry plates replaced it. The tintype is its cheap, durable variant — collodion poured onto a thin sheet of japanned iron rather than glass, exposed wet, and developed within ten minutes before the plate dried. It is the look of Civil War portraits, frontier daguerreotype-era studios, and turn-of-the-century carnival photography. Visual rules: extremely shallow depth of field from large-format optics with no f-stops above f/8 in practice; long exposures (1–30 seconds), so subjects must hold still or blur; collodion's blue-sensitive emulsion renders skin tones dark, blue eyes nearly white, and red lips black; pinholes, comet streaks, and chemical irregularities at plate edges; dense black backgrounds from the japanned iron base; a slightly silver-blue or warm cream tonal cast depending on the developer formula. Modern revival photographers use traditional plate chemistry, not digital filters. Use it for historical period portraits, Civil War / frontier reenactment, gothic-tinged formal portraiture, occult and tarot imagery, traditional craft branding, and any image that should feel like a singular physical object rather than a reproduction. Models will produce "vintage sepia photo" if asked vaguely. Specify "wet-plate collodion tintype, blue-sensitive emulsion rendering skin darkly and blue eyes pale, long exposure with subject held still, shallow depth from large-format lens, chemical irregularities at plate edges, japanned iron base, 1860s formal portrait."
