Bromoil Tranfer Print


Assignment 1 - Historic Photographic Processes

Bromoil transfer prints
Windmill : Robert Demarchy 1907

Key Elements that distinguish the Process
The process revolves around the old adage: Oil repels water!

The Bromoil process belongs to the oil print family of photo processing, along with oil and mediobrome.

The primary difference between the oil process and bromoil process is that the oil prints uses an enlarged negative to start with, as the gelatin used in silver positive was too slow to permit an enlarger to be used, so negatives had the same size as the positives.  By using the Bromoil process, one creates a smaller negative in an enlarger to produce the silver bromide positive.

The Bromoil print process –essentially an "oil print on Bromoil paper"
1.Photographers take a silver gelatin-sized print and soak it in a bleaching bichromate solution so that only a faint trace of the image can be seen.  The bleached print is called a “matrix”, as the gelatin hardens selectively where the light hits the paper.

2.Once dried, the Matrix is soaked in water, dried and the gelatin swells- except in the areas where it hardened. Then oil-based lithographic ink is applied to the surface to rebuild the image and sticks to areas of hardened gelatin. The water-swollen areas repel the ink. The silver based image is replaced with an ink image, which is a far more permanent image. The bromolist uses their artistic control to create this image by their brush strokes.

The bromoil transfer print takes the bromoil print and places it against artist paper and then pulls it through an etching or bromoil press. This leaves a layer of pigment on the paper, which takes on the texture of the transfer paper. It is possible to make several copies of the “one of a kind” bromoil print using this method.

 Heinrich Kuhn The Reaper 1924
Inventor/s
•The Bromoil process had its’ roots with the development of the oil print. In 1839 Scottish photographer Mungo Poton used a potassium bichromate process (which was much cheaper than silver) to create an image, This was a very yellow image that didn’t catch on. In 1855, A.L. Poitevin  spread oil-based ink on a silver print with a roller. This process was further developed by G.E.H Rawlins, who introduced spreading ink selectively on a print with a brush in 1904.

•The British photographer C. Welbourne Piper is credited with inventing the bromoil process in 1907. He worked with EJ Wall, who had worked on a theory about this but had never explored creating this process. 
                                   
Fred Judge invented bromoil transfer print in1909, which allowed photographers to make several transfers from the original bromoil print.

Important photographers of Bromoil transfer prints:

•Principal European photographers employing this process:
Robert Demachy and Heinrich Kuhn.

•Principal British G.L. Hawkins and Sam Weller .
Weller established the Bromoil Circle of Great Britain in 1931, which still exists today.

Typical way Bromoil transfer prints are used:
The bromoil print was most popular during the photographic period called the Pictorial Period in Britain and Europe in the early 1900s. Pictorialism is considered the first art movement in photography and was fading by 1910. Alfred Stieglitz is credited with moving photography in a more realism period with the formation of the “Photo-Secession Group” in America. Pictorialism emphasized an imaginative and impressionistic approach to photography, rather than realistic imaging. Major topics focused on portraitures, still life’s, and landscapes. The Bromoil transfer print is still used today by “Art” photographers and one can purchase Bromoil kits. See David W. Lewis recent bromoil photography:http://www.bromoil.com/Site-Files/Site-Pages/Galleries-1

How to Identify and Date examples
Identification: (characteristics taken from Institute of Photographic Technology-http://www.iptaustralia.com/page16/page37/page38/page40/page40.html)

•Pattern:
Irregular stipple pattern –the grain will vary in coarseness because of brush used
Edge definition
 Lack a sharp focus –edges have a “soft” appearance, not crisp
Image:
On the top of the print, not buried in the emulsion
Support Paper
Bromoil print: pigment image on gelatin paper base
Bromoil transfer print: image on art paper
Plate mark:
Present because a press is used to transfer the image
•Can be printed in black and white or in a 4 color method, but the oil base typically creates a yellow hue.
•Photos resemble a painting, drawing or engraving.

Dating:
Most photos date from the 1907-1930s. Because the process is always unique to the photographer, it is difficult to date modern from older prints. The paper age will help determine the photo’s modernity.

Preservation Concerns
The Bromodial transfer print is as permanent as the paper support and pigments used in the process. If good paper was used and the print stored properly it should last a very long time.

For bromoil prints that weren’t transferd to art paper, poor rinsing of the chrome salts can lead to discoloration under influence over time. Apparently washing all the bromate stain off is essential for the process to be correct.

The irregular thickness of the gelatin layer can, in unfavorable conditions, lead to stresses in the pictorial layer.
