“Photography historians are each different in how they approach studying the life of the medium: some are interested in its technical history, asking what camera improvements, and limitations, meant for the people who became photographers,” Gabrielle Moser told Bored Panda.

Gabrielle is a writer, book author, independent curator, and Assistant Professor of Aesthetics and Art Education at York University. She was happy to share some insights into the wondrous world of historical photography and what photography historians do to bring them back to life.

“What could you literally photograph—because of film speed, exposure times, and the ability or inability to print multiple copies of an image—and what did that mean for the kinds of images that were made?” These are the inquiries photography historians are looking for the answers to.

“For instance,” Gabrielle continued, “war photography was incredibly difficult until the early 1900s since shutter speeds were so slow and exposure times were so long that any movement, like armed battle, wouldn’t be captured by the camera. That didn’t mean that photographers didn’t make images of wars, but that they had to be inventive, using staging, re-enactment, or capturing the aftermath of battle, as Roger Fenton, Mathew Brady, and Timothy O’Sullivan were all very skilled at.”

The professor explained that many important photography historians have also traced where these images circulated, who would have seen them, and in what context: “did they have captions? Were they shown in newspapers, or in more spectacular settings like lantern slide presentations, or through a stereoscope which produced a 3D effect for the viewer? Were they used by the government for the purposes of surveillance, or by activists to make claims for social change?”

“Other photography historians are curious about how photography was used as a fine art form and about how artists like Julia Margaret Cameron, F. Holland Day, and Berenice Abbott adapted the medium to make photographs that were taken as seriously as paintings and sculptures from the same period.”

More recently, there has been an interest among photography historians in the social life of photographs. “It focuses less on the artists who made the images and more on the people who are in them. These historians ask how photographs might be used to claim rights, like citizenship, or to protest social and political injustices,” the professor explained and named some important figures who used images for social justice: “Photographers like Lewis Hine, Raja Deen Dayal, James van der Zee, and later Roy DeCarava, Susan Meiselas, and Zanele Muholi.”

When asked how photography historians determine the date, context, and the participants of the particular photograph if there are no apparent indications, Gabrielle said that most photography historians rely on their technical knowledge of photography to date images that are “orphaned" from their captions.

“We examine the photographic print—its dimensions, the quality of the image, its wear and tear—to determine what kind of camera or printing technique was used. Daguerreotypes produce a mirrored surface, a high level of detail and contrast, but could only be made at very small scales, for instance, while salt prints could be much larger, and printed on paper, but sacrificed a level of detail.”

Turns out that “early Kodak cameras were the first widely available and cheap mass-produced cameras in North America, introduced in 1888,” Gabrielle said and added that they have particular prints that produce a circular image.

“Determining the context in which an image from the past circulated can be much trickier. Historians often have to look to archives of illustrated newspapers to see if photographs were reproduced there, and often with photographs made for press agencies, like Magnum or Black Star, stamps and captions are included on the back to indicate where the image was seen.”

However, in the case of private or domestic images, “like portraits, family photo albums, passport photographs, or class photographs,” the professor said that we might not ever know everything we want to know about who is in the photographs, or what context in which they were made. Having said that, she added that “we can use our imaginative capacities to speculate and make educated guesses.”

According to Gabrielle, as digital photography has become accessible to almost everyone through smart phones, we have begun to value historical photographic processes, “especially ones that have been made obsolete, more highly. Especially the processes that resulted in one-of-a-kind images, like photograms, daguerreotypes, cyanotypes, and Polaroids, because they seem unique and irreproducible.”

“In many ways, the more we know about the history of photography, the more we seem to find parallels between now and the past. We might worry that there are 'too many images' in the world through platforms like Instagram, TikTok, or even in the millions of photographs uploaded to Flickr and Facebook each day, but if we look back at some of the earliest cartoons and caricatures about the invention of photography in France in 1839, we see the same panic surrounded the first viable and publicly available photographic method, too,” Gabrielle concluded.
