How does an expert go about studying an old photograph to determine when it was made, where it was taken, who’s in it, and what process was used to make it? This week on Getty Voices, Miriam Katz shares her fascinating work as a cataloguer—aka photograph sleuth—in the Getty’s Department of Photographs, revealing what her job is all about and sharing tools and tricks to help you become a photograph sleuth, too.

Back in college I took some aptitude and vocational tests to determine an ideal career. One of the results was detective. “Ha!,” I thought to myself. “That’s totally at odds with my art history major.”

Fast-forward 20+ years, and I spend as much of my time looking through a magnifying glass as a classic detective does—solving the mysteries of the Getty’s Department of Photographs.

As primary cataloguer for the department, I’m responsible for making sure our database is accurate and complete, a ready reference for people who want to access our collection. My goal is to capture as much information as possible about each photograph and record it in our database. At a minimum, I try to determine the photographer, medium, subject or title, date, and location. Sometimes the process is straightforward, and sometimes it is a bit more challenging. Sometimes a photograph is signed, titled and dated, but frequently it is not.

I follow leads in dozens of directions. I learn something new every day. One day I might be researching Broadway shows of the ‘20s, hoping to recognize an actress, and the next day I might be looking through churches in Florence to identify a particular tomb. Recently I’ve been learning about Britain’s royal family in preparation for an exhibition about Queen Victoria we will be presenting in 2014.

The Getty’s photography collection spans the history of the medium, from Talbot’s photogenic drawings of the 1830s to large digital works made by living artists. We have an amazing number of 19th- and early 20th-century photographs by little-known photographers. I channel my inner sleuth to consult fashion books, the history of automobiles, architectural studies, and more obscure literature to pinpoint the fashion, cars, and buildings that will help me date an image.

The photographs themselves can be mysteries. “Photograph” is a broad term. The Getty’s collection includes daguerreotypes, salted paper prints, calotypes, albumen silver prints, platinum prints, gelatin silver prints, collotypes, carbon prints, carbro prints, chromogenic prints, inkjet prints, and more. Ten years ago I would have divided photographs into two categories: black and white or color. Now I examine each print to determine the chemical processes used to create the image. Like a detective, I look for clues. How thin is the paper? How large is the print? How glossy is it? Has the image deteriorated? Through a magnifying glass, can I see the paper fibers? Can I see individual drops of ink? When I’m not certain what I’m looking at, the photograph conservators in my department will examine it with a microscope or other tools.

A friend recently thanked me for inspiring him to pursue a museum career. He said that I always made my work sound fun and exciting. I hope that over the course of this week I can convey that enthusiasm to you also, as well as share some of my tips, tools, and resources that I use to sleuth photographs.
