An artist's archive of photographic images printed on stones that have been gathered, exposed in the darkroom, and returned to their home environments in rivers, on beaches, in parks and quarries, and on concrete city sidewalks. Petrographs juxtapose the brief span of our "snapshot" memories with the expanse of geological time, and reveal not only how place shapes us, but how everything we do imprints, for better or worse, on the environment.

Petrographs

Marguerite, Sandwich Beach Installation I, 2006
“Petrographs” are photographic images printed on stone.
Photography has been called the process of “drawing a man’s shadow to stone.” Petrographs make the metaphor literal. By casting and briefly fixing our shadows on the bedrock, they juxtapose the short span of our mortal memories with the expanse of geological time.
The photograph above was taken on a stormy day at Sandwich Beach on Cape Cod, in April, 2006. Earlier that year I’d collected large pebbles from the beach—a place thick with memories for me—and then coated the rocks with photo emulsion and printed them in a darkroom. This is an image of my friend Marguerite, from 1988. I then returned Marguerite’s petrograph, along with many others, to the beach where I’d found them, and let the sea have its way with them.
A storm blew in and waves tossed some of the petrographs ashore, coating them in sand, and took others out to sea, never to be seen again. Still others, like the rock depicting Marguerite, were burrowed into the wet sand and scoured by rushing pebbles. The image above and those below, depicting the same rock seconds earlier and later, were not computer generated in Photoshop: they are the result of the environment absorbing, changing, and ultimately erasing my memories.
My name really is Pamela Petro. I was lucky when it came to naming my medium.


There are several individuals I'd like to acknowledge without whom this art installation would not be happening: Jackie Coe, Northampton's Elementary School Art director; Meredith Brown, Director of Marketing and Events for the Lathrop Retirement Communities; Kerry Buckley, Executive Director of Historic Northampton; and Bob Reckman, Ned Huntley, and members of Northampton's Department of Public Works Board. You all have my appreciation and deep respect. Thank you.

In September 2007 I gave 60 fourth-graders at the Jackson Street School in Northampton, Massachusetts black and white disposable cameras. I also gave cameras to participating residents of the Lathrop Retirement Community, just around the corner from the elementary school. Both young and old photographers had one mission: to record their lives in Northampton—the people, animals, foods, flowers, clothes, and landscapes that they love.
They did a stupendous job. Photographs poured in of city streets, local farms, cats, dogs, rabbits—one gerbil—friends, parents, children, brothers, sisters, dolls, the Red Sox, Spider Man, and my favorite, a waffle iron.
With the help of faculty, staff, and students from Hampshire and Smith Colleges and the University of Massachusetts--especially Dan Wessman, at UMass--from mid October through early-to-mid November I printed the children’s and seniors’ pictures directly on the sidewalks of Northampton, for the whole city to see. The images, or petrographs, were printed directly on concrete—a process that required a generator, a slide projector, a hairdryer, luck, and lots of Liquid Light—and were about two feet by a foot-and-a-half in size.
Exposed to sun, rain, and foot traffic, they only lasted a short time (like the perspectives of the young and old) before they disappeared entirely. The photographs that follow were taken from a day to a week after the sidewalk petrographs were printed. They are in 11 x 14 format and larger, and are currently on display at Jackson Street Elementary School.

This petrograph was printed on a walkway between the Hotel Northampton and Gothic Street, in downtown Northampton. The image is in the Howe's Brothers Collection at Historic Northampton; it shows Annie Starks receiving meat from her butcher, James Hill, at her home in Florence. It was taken between 1886-1902. Below is a digital image shot immediately after the petrograph was printed.

Fleeting Fossils Scrapbook: Images and Notes
The first picture is a test image I made with my assistant, Suzanne Carlson, a student from Hampshire College. The second shows Suzanne watering the print after it’s been developed and fixed.
16 October 2007: The launch of the Fleeting Fossils outdoor exhibition! We attempted to make two sidewalk petrograph prints, and had a 50% success rate. The first image, in front of Iris Photo & Digital (164 Main St.), was taken by a fourth grader at Jackson Street School, and came out respectably well. It was our first attempt, and Suzanne and I--along with Jon Coe, who's joined the petrograph team, and a small crowd of onlookers--cheered.
This is a test print that Suzanne and I made for the Department of Public Works, on 9 October. The image, of a baby and young girl in front of 38 Fruit Street, in Northampton, is from the Howes Brothers Archives of Historic Northampton, taken c. 1900.
This smiling couple was taken by Stan, a resident at the Lathrop Retirement Community.
This picture was taken by Varn, a resident at Lathrop. We over-developed the print, but the image--three well-dressed ladies at the Lathrop Community Center--is quite legible.
28 October 2007: Another good night of printing. Renowned calligrapher Tom Ferguson and I made two prints across the street from the previous set, at the foot of Main Street just before the railroad bridge (between the Toasted Owl and Thai Garden).
This picture of a gentleman in a lawn chair was taken by Phyllis, a Lathrop resident.
This petrograph, of three women participating in an inter-generational dance troupe, was taken by Ev, also a resident of the Lahtrop Retirement Community.
29 October 2008: Last night Suzanne, Jon Coe, and I made 2 prints in front of the Smith Art Museum, on the Elm Street sidewalk. The first one, just below, came out splendidly. The second image was stippled--perhaps we didn't dry the emulsion long enough, or the cold prevented it from drying--and obscured the subject's face. My apologies to Hunter, who took the picture!
These are Hunter's images. On the left is his snapshot; on the right is the petrograph that didn't quite work out...Sorry, Hunter!
30 October 2007: Another excellent night of printing, this time on Pearl Street, opposite East Side Grill and directly in front of the New York Shop Exchange. The digital picture of Ella's M's image is in the gallery above.
7 November 2007: I guess I was getting too cocky...Last night I tried to print alone on Masonic Street, but was too close to the corner of Center. Once again the first print was completely fogged by sweeping headlights--so much so that I didn't attempt the second. So much for learning from lessons. Hopefully Suzanne and I will redeem the mistake on the 8th!
The evening was saved, however, by a passerby. He stopped to see what I was doing, but I told him the print hadn't come out. "Oh," he said, "there're some other people printing on the sidewalks here in town. You should talk to them. Their prints are really cool." I looked at him and thought, "How many people do you think are out in 35 degree weather, making petrographs on the sidewalks of Northampton?" But I didn't say that. I just thanked him for the tip.
8 November 2007: All is redeemed. Suzanne and I made two superb prints at Roundhouse Plaza, just around the corner from the Northampton bus station. It was the coldest night yet: my car thermometer read 33 degrees. This slowed the developing time dramatically, yet the cold proved to work in our favor. We had more time to control the process, adding fix selectively where needed; when the images finally appeared, the rush of magic made my heart skip beats. The digital image of Glorianne's picture is shown above.
11 November 2007: A trifecta! Despite the bitter cold, Suzanne and I printed three images in a row on the walkway between Gothic and King Streets (just off Gothic, between the courthouse buildings). The theme was transportation, with the images featuring skateboards and scooters; a car wash; and an picture from Historic Northampton of a horse and wagon, taken around the turn of the century. (The digital version of the historic image is shown above.)
In the way of things, just as we're hitting our stride as printers, the installation is coming to an end. We have only two more sessions, on 12 and 13 November. It's been a great ride, but we'll be glad to come in from the cold...
Suzanne developed our farewell image. Of the two of us, Suzanne proved to have steelier nerves when it came to developing. (The question was always 'When to fix?' Suzanne was good at waiting till the last moment, before the image became too dark; I sometimes panicked, and fixed too soon...).
Here's the petrograph printing team: Suzanne on the left, Pam on the right. I want to publically commend Suzanne: from the first test print she's been the best printing partner I could have hoped for. Smart, resourceful, problem-solving, reliable, good-natured, and intrepid. Thank you, Suzanne!

“Petrographs” are gelatin silver images printed on stone.
Upon seeing a camera for the first time, natives of northeastern Siberia called it a “three-legged device that draws a man’s shadow to stone.” Petrographs do the same. By casting and briefly fixing our shadows on the bedrock, they juxtapose the “snapshot” span of mortal remembrance with the vastness of geological time.
I grew up with rocks in the house—my father is a mineral collector—but petrographs can’t be domesticated. After harvesting rocks from rivers, beaches and quarries and printing them, I return them to their original environments where I monitor them for days and even weeks. As the petrographs settle back into their landscapes their images, exposed to the elements, weather and erode.
Some impressions vanish rapidly. Others are tenacious. In all cases—including series printed on concrete city sidewalks and on alternative “canvases,” including fungi, leaves, feathers, and pinecones—environmental installations are ephemeral. The sequence of presence and disappearance, recorded in the documentary photos I make on site, is the invisible “art” of the endeavor.
