LABELS: BIKERS
Original Works by Tim Telkamp
In his portfolio Labels: Bikers, Tim Telkamp explores the dichotomy that exists between the personal labels we use to make introductions to “outsiders” individually or as a group, and contrasts that to the labels that “outsiders” might apply when seeing that group together.
TINTYPES: A COMMUNITY PORTRAIT
Selective works by Tim Telkamp and Leah Sobsey
Tintypes: A Community Portrait is a collaboration between Leah Sobsey and Tim Telkamp. In 2017, the pair were the recipients of the Click! Photography Festival PIC Grant (Programming Innovations for Click). The goal was to engage with the community and bring people together through photography. The idea was similar to that of the book mobile or the ice cream truck–essentially, people were invited to come out of their houses and onto the street to engage with each other and in the process create a large community portrait.
The project spanned a few weekends, with the artists routinely taking their mobile tintype unit out into the community. Setting up across the Triangle in downtown Durham, North Carolina one day, on another day at a Habitat for Humanity worksite, and finally, to end the project, at a residential warehouse/art-studio location. While they had hoped to entice a representative few from each location to participate, they found themselves greeted with overwhelming interest from the entire community. Portrait sessions were usually filled by noon for the whole day, with some electing to wait in line with the hope of getting a tintype made. The artists pushed their limits, wishing to accommodate everyone possible. The resulting body of work, over 80 tintypes in total, exceeded the vision of the grant as well as their expectations. A smaller selection of these tintypes were chosen for display at the Southest Museum of Photography

THE TINTYPE PROCESS: AN OVERVIEW
The traditional tintype process involves a light-sensitive collodion emulsion (containing suspended silver halide crystals) coated on a thin sheet of metal and treated with a potassium cyanide fixative for permanence.
Did you know? First formulated in 1846, collodion was, and still is, used as a medical dressing. It is made from cotton soaked in nitric and sulfuric acids that is thoroughly washed and dried, then dissolved in ether and alcohol. When allowed to dry, collodion leaves a clear, thin, tough flexible coating. In 1851, Frederick Scott Archer suggested it was a perfect vehicle to hold light sensitive chemicals on glass for making negatives. Also called "cellulose nitrate," it is similar to the base used later for making the first flexible film.
The traditional method for creating tintype photos utilizes a wet collodion process. Collodion is a syrupy solution of cellulose nitrate in ether and alcohol. In the case of tintype, the wet collodion is carefully applied to a thin iron plate–which must be tilted by degrees–allowing the photographer to coat the entire surface with the solution.
Any excess collodion is drained back into its bottle.
While the plate is still wet (before the ether and alcohol evaporate from the collodion) it must be dipped into a solution of silver nitrate in a darkroom (under red or deep amber light) where it remains for a few minutes. At this time the silver nitrate bonds with the iodides and bromides in the collodion to make light-sensitive silver halides on and just under the surface of the collodion.
While the plate is in the silver nitrate "bath," the camera is set up and focused on the subject.
The light-sensitive plate is removed from the darkroom in a light-proof holder and then attached to the camera. A "dark slide" or covering is pulled to expose the plate to the inside of the camera. Exposure is made by removing the lens cap. It can take approximately a second or two (or longer) to make the proper exposure, depending on the age of the collodion, type of lens used, and the quality of light on the subject.
After the exposure is made, the plate holder is secured, removed from the camera, and brought back to the darkroom. The plate is removed from the holder and the developer, a dilute solution of ferrous sulfate (iron), acetic acid, and alcohol are gently poured onto the collodion side of the plate and rocked. The image gradually becomes visible within a few seconds as the areas exposed by light entering the camera are converted to metallic silver. When development is complete in a minute or two, the developer is removed by thoroughly washing with clean water. The plate can now be safely taken out from the darkroom.
The developed plate is placed into a tray of sodium thiosulfate (also known as sodium hyposulphite) or potassium cyanide, to remove the unused silver halides. It is then washed well with fresh water and allowed to dry.
Once dry, it is coated with a protective varnish made from gum sandarac, alcohol, and oil of lavender. The sandarac varnish is extremely sticky until thoroughly dried.
CENTURY STUDIO NO. 7 FILM CAMERA
Capturing Modern Portraits in Classic Style
“Big Al” is a Century Studio No. 7 8x10 film camera built sometime before 1910. This is one of five working 8x10 format cameras that I use regularly for wet plate collodion and traditional film photography. Some of the “Tintypes: A Community Portrait” plates in the gallery today were made with Big Al, while others were made with a Seneca 8x10 or a Kodak 2D, all of similar vintage.
While none of these cameras were originally intended for wet plate work, I have hand made my own plate holder system and fitted it to each of these cameras.
Big Al was a gift from my dear friend and the amazing photographer, Catharine Carter of Chapel Hill, NC. She and I had made a trip to visit a mentor in West Virginia. We found Al as part of an estate sale and he came back to her studio in my truck. She used him to make 8x10 negatives for platinum/palladium, but when she retired and downsized her studio he needed a new home and she wanted Al to keep working. So here he is, still making negatives for alternative process work and now making wet plate collodion plates too.
