Platinum printing dates back to the late 19th and early 20th centuries, when it was embraced by master photographers like Alfred Stieglitz, Edward Steichen, Paul Strand, and Irving Penn. Because it occurs in such small concentrations deep within the Earth’s crust, extracting platinum is both complex and resource-intensive. This contact-printing process results in deep, velvety blacks and a smooth transition between tones, creating an almost three-dimensional quality in images. This causes the platinum to precipitate out of the solution as a solid salt, ammonium hexachloroplatinate. This typically involves solvent extraction, precipitation, and ion exchange to produce high-purity platinum metal ready for commercial use.
