Historical contribution
What Archer contributed
Frederick Scott Archer’s wet-collodion process, published in 1851, combined glass-negative detail with reproducibility. It required portable darkrooms because the plate had to remain wet. Gelatin dry plates in the 1870s removed that immediate processing constraint and enabled faster shutters, factory-made plates and greater amateur participation.
Why it mattered
Preserves detailed selected visual traces for later inspection and reproduction.
