Diana Bloomfield Teaches Tri-Color Gum Bichromate Workshop

This past weekend of September 12 and 13 Art Intersection was bursting with color! Tri-color gum bichromate, that is. We had the great pleasure of hosting a two-day, immersive workshop in the process taught by Diana Bloomfield, a master gum printer especially known for her tri-color technique. Ten participants learned about this fascinating 19th-century process that includes mixing together gum arabic, potassium dichromate, and watercolor pigments, then hand-coating that mixture on paper, exposing their paper under a digital negative in UV light, and washing out the print in water to “develop” it.

Diana Bloomfield explains her technique for mixing the gum emulsion on Day 1.

Workshop participants look on as Diana coats a sheet of paper with the light-sensitive gum mixture she’s made.

Any color watercolor pigment can be used, but this tri-color process involves making three separate coating and exposure runs with cyan, magenta, and yellow pigments individually to get a full-color final print.

Armed with coffee, the participants listen as Diana explains the basics of color balancing for a natural-looking print at the start of Day 2. If a print does not initially look correct, more passes with various colors can be made to balance it.

In order for the image to remain sharp, the negative being used must be placed in exactly the same spot for every layer. Michael Puff carefully registers his negative to exactly match the previous layers he’s created.

Chris Palmer rinses out his print after exposing it to UV light. During the exposure, the areas of the gum emulsion blocked by the dark areas of the negative wash away in the water, creating highlights. Those underneath the light areas of the negative solidify and adhere to the paper, creating shadows.

BK Skaggs, Shari Trennert, and Maylee Noah rinse their prints while others hang to dry. These prints show the first pass with the cyan layer.

At the end of the workshop, all the participants show the results of their hard work by putting their favorite prints up on the critique board. Diana gives the class constructive feedback on their printing.

Teen Photography Camps, Summer 2015


What a great summer for photography! In June and July high school students escaped the heat and came to Art Intersection to learn the basics of photography, expand their skills, and build portfolios. Each week teens from all over the valley worked with Art Intersection staff and volunteers to create finished works of art.

During the Exploring Photography camp, teens were introduced to the foundational elements of photography. Students experienced a hands-on approach to learning several different methods of image capture and printing using both digital and analog photographic practices.




The Advanced Photography students explored a wide variety of specialized techniques such as large format photography, gelatin silver print toning, stop-motion animation, and lumen printing. By the end of the week these teens were armed with an arsenal of new media to expand their photographic repertoire.

Pinhole Photography at the Arizona Railway Museum

On Sunday, April 26, the Arizona Railway Museum open the gates for pinhole photographers to make images for worldwide pinhole day. About 10 photographers took advantage of the cool weather and access to many of the train cars on exhibit at the museum.

Images were captured on a variety of media, from 35mm to 4×5 to 5×7 film, digital, and paper negatives. Another great Arizona day to make unique pinhole images. Be sure to visit the Worldwide Pinhole Photography website and the Art Intersection Gallery for more information and to visit their galleries of images.

Local Photographer Travels to Romania

Local Photographer Travels to Romania,
Lives Daily Life of Peasant Ancestors

For 25 years, local photographer Emily Matyas captured the Mexican spirit and heritage on film while living in Sonora, Mexico. In October, she decided it was time to catalogue her own heritage, a journey that would take her to the distant peasant villages of Romania.

For Tempe photographer Emily Matyas, her deceased father’s Romanian heritage was always a mystery, a missing piece in the puzzle of her sense of self. In Oct. 2013, she decided it was time to fill in the blanks.

With friend and fellow photographer Kathleen Laraia McLaughlin, an adjunct professor at Loyola Marymount University in Los Angeles, Emily made her way to the Romanian village of Sarbi, where she would spend 10 days taking self-portraits as she lived the life of her peasant ancestors — wearing the traditional garb, helping with the exhausting chores, and interacting with the locals.

“I decided to photograph myself as if I were my grandmother, as if I had lived there all my life,” Emily said. “You can hear all the stories you want about your relatives, but when you actually go and experience their lives, it is a totally different level of understanding.”

Though Emily admits she often felt like a fish out of water living in a village of outhouses, haystacks and ancient customs, she said the trip helped her understand her identity more fully.

“This experience had to do with belonging,” said Matyas. “I had to find out where I belonged and this trip made me feel complete. If people have questions about their heritage or identity, then these photos may represent a way to find what they are looking for.”

People will have the chance to view Emily’s photographs, along with seven other up-and-coming photographers, during “Home Bound,” an art exhibition Jan. 17 to Feb. 28 at Gilbert’s Art Intersection (207 North Gilbert Road, Suite 201, Gilbert).

“The exhibition looks at the main differences of perspective on what we think of as home,” said “Home Bound” Curator Carol Panaro-Smith. “The work is full of beauty, but also makes us think about our home, experience and heritage.”

Other photographers featured will include LA-based artist Kristin Bedford, whose images of the “Father Divine” religious sect were recently featured in the New York Times, and Daniel Coburn, a Kansas-based photographer whose first book “The Hereditary Estate” is due for release April 14.

“People are bound to home, for better or for worse,” said Matyas. “I would hope that the viewers can take away different meanings of home that support and guide them in their lives.”

Tintype Workshop and Open Studio with David Emitt Adams

Mid-ninteenth century tintype photography is experiencing a resurgence as photographers look for a unique aesthetic for portraiture and still life images.

David Emitt Adams led the weekend of tintype creativity starting with a free lecture on Friday evening, the all-day workshop on Saturday, and  an open studio on Sunday.

Two stations with 4×5 cameras were setup, one for still life props and the other for portraits.

Keith shared his expertise with the class and showed the process he uses to make palladium and platinum prints. You may remember Keith’s work on exhibit in the North Gallery along with Dick Arentz this past January and February during the Art Intersection Platinum/Palladium exhibition.
