E-Projects: Tintypes In Motion
Sept 2, 2010
By Holly Stuart Hughes
Photographer Antonio Martinez created the stop-motion video as an experiment in fusing old and new, analogue and digital photographic techniques. He used Photoshop and Final Cut Pro editing software to blend his tintype images, created with a dry-plate technique developed in the 19th century. Both the video and the tintype images that make up the sequence have been exhibited at Los Manos Gallery in Chicago and were recently on view at Blue Sky Gallery in Portland, Oregon.
Martinez began creating tintypes while he was in graduate school at the East Carolina University in Greenville, North Carolina, after he attended a workshop in vintage processes with photographer and printer Scott McMahon. "There was something just magical and alluring about the modern tintype process when presented by Scott," he recalls. Rather than using the classic wet-plate collodion process, McMahon suggested a dry-plate technique. "The dry-plate process involves coating anodized aluminum with a silver gelatin emulsion, which is then air-dried," Martinez says. Using this method, he can prepare batches of sheets—as many as 300 at a time—by coating them with silver emulsion. "When they're dry in the morning, I can use them anytime."
With a traditional wet-plate process, he says, "I would have to coat, expose and process in a short, limited amount of time. The dry-plate process could be used with any positive image, whether it was from a silver print, enlarged digital positive, or even a color slide enlarged to the size of the metal." Martinez, who shoots 35mm Tri-X, enlarges his negatives to 4 x 5 to create a transparent positive, then contact-prints the positives on the sensitized aluminum plates and develops them using a developer he purchases online. "For a grad student on a budget and working primarily with the 35mm camera format, the modern tintype process was the answer in making a unique photographic art object."
He enjoys what he calls "the finicky process" of printing tintypes, but what first sparked his interest was when he heard that tintypes were once considered "the poor man's daguerreotype." Martinez, who was raised in Oklahoma, says he strives to make images "that celebrate the middle-class condition." He attended and photographed his first circus in 2006, attracted by "a collectively shared activity and experience that the community valued." Since then he has photographed many other arena spectacles conducted in small towns: body-building competitions, rodeos, bull riding contests and, most recently, amateur cage-fights. By printing these images as tintypes, Martinez gives the images both a mysterious allure and a timeless quality.
Honing his tintype technique has required trial and error. "I experimented with different developer recipes, emulsion brands, sources of positives and substrate surfaces and sizes," he says. He now orders ready-made developer online through Rockloid Colloid Corporation, located in Piermont, New York, and uses Kodafixer to fix the emulsions. Martinez also varnishes his tintypes, which he says deepens the blacks and brightens highlights.
