Light Sensitive

To celebrate the art of handcrafted prints, Art Intersection presents Light Sensitive, our eleventh-annual, international juried exhibition of images created using traditional darkroom, historical, and alternative photographic processes and methods.

In the current takeover of imagery presented on computer screens and the overwhelming volume of digitally printed pictures, the purpose of our Light Sensitive exhibition is to celebrate, promote, and reaffirm the art of handcrafted prints that uniquely belong to the tradition of light sensitive creative processes. Each year we search for work representing creativity, passion, and display of the beauty these light sensitive processes bring.

Acceptable Processes include, but are not limited, to: silver gelatin prints, albumen, anthotype, argyrotype, athenatype, Bayard direct positive, calotype, carbon, casein, chrysotype, cyanotype, dusting-on process, gum bichromate, gumoil, Herschel’s breath printing, photopolymer gravure, Ivorytype, kallitype, mordançage, platinum/palladium, printing-out-paper, solarplate intaglio, van dyke brown, wet plate collodion, whey process, Ziatype, combinations of any of these processes, and all photographically based image-making techniques that incorporate traditional studio-based mediums such as printmaking, ceramics, or painting.

He received his B.A. Degree in Visual Arts from the University of California at San Diego, an M.A. from Stanford University, and his M.F.A. from the University of New Mexico and served as a Professor of Photography for over 35 years, and Chair of the Department of Art and Art History at San Jose State University.

Tri-Color Gum Printing with Diana H. Bloomfield

We have a full class of students.
Please call or email to be placed on a wait-list.
480.361.1118 – info@artintersection.com

In this intensive two-day workshop, we will learn how to print in the 19th century photographic process of gum bichromate. Using color separation negatives, we’ll learn how to make multilayered, tri-color gum bichromate prints on watercolor paper.

After mixing an emulsion of watercolor pigment, potassium dichromate, and gum arabic, this mixture is brushed on watercolor paper, dried, and by placing a negative on top it is exposed to UV light.

We then ‘develop’ the prints in plain tap water. Layers are built by repeated coatings and careful registration of negatives until a full, rich image is achieved.

We will also explore one-coat, gum over cyanotype, made using black and white negatives.

No prior experience with this type of printing is necessary, so join us for two days of fun and experimentation with this interpretive, intuitive, and infinitely creative photographic printing process. Once you experience the joy of gum printing, you will never be the same!

The making of digital negatives will be shown, but for the workshop itself, please send four color image files (300 dpi at 10” on the long side), and one black and white image file if you would like, at least one week prior to the workshop.

Please complete the WORKSHOP SIGN UP FORM attached below before payment!

Thank you to our sponsor Hahnemühle.

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.

Tri-Color Gum Bichromate – Round 2

Our first Tri-Color Gum Bichromate workshop with Diana Bloomfield last September was such a hit, we decided to do it all again! This past Saturday and Sunday Diana led nine students through this labor-intensive and difficult process. The workshop included many first-time gum printers, and despite the tricky nature of the process, all produced fantastic prints! As we gathered around to look at everyone’s completed work at the end of the two days, one thing was apparent: there is nothing like the magic of gum printing, and no one better to teach it than Diana Bloomfield!

We are grateful for all of our students, but we especially would like to extend a big THANK YOU to our four class participants who travelled from far, far away to take this workshop with us – Cary from Alaska, Timothy from Michigan, and Scott and Kelly from Pennsylvania. We’re so glad you could join us!

Karen coats her paper with a mixture of watercolor pigment suspended in potassium dichromate and gum arabic. The potassium dichromate hardens the gum arabic upon exposure to UV light; the parts of the coating blocked by the negative remain soft and wash away in water.
