A SHORT HISTORY
The Pannotype was an
inexpensive (and therefore attractive) process first introduced by Wulff and
Co. in 1853 as an alternative to the fragile glass and paper supports of the
time. Used only for portraits, the process resulted in a direct positive collodion
silver photograph on a support of waxed textile fabric. These images were
mainly transferred onto black oilcloth and patent leather, as the word
pannotype stems from the Latin ‘pannos’ (meaning ‘cloth’). Common formats include Carte-de-visite
and cabinet cards.
THE PROCESS
The George Eastman House
explains how this process was executed:
“These direct
positive collodion images were made on glass and transferred onto a
secondary support material by placing the glass plate bearing the image in an
acidified water bath that caused the collodion film to shrink. The secondary
support was then placed in the water and the two were taken out of the bath
with the image in contact with the surface of the secondary support. The back
of the support was then pressed against the glass with a squeegee and the
plate. The back of the plate was then gently heated until the image and support
fell from the glass.”
The transfer of the collodion
(ambrotype image-carrying) layer onto a waxed textile reduced all danger of
breakage and therefore made it possible to keep the photograph in an
album/portfolio/locket/etc.
PRESERVATION AND
IDENTIFICATION
Once dry, the image adheres
strongly to fabric and resists even vigorous rubbing. This does not apply to
long-term preservation however, and pannotypes are an extremely rare find
today. Unfortunately, pannotypes are rarely found in good condition. Deterioration
will often reflect the following:
- Reduced contrast
- Collodion often cracked
- Brittle/fragile textile support
When caring for a pannotype, one should:
- Put into a protective mat if not framed
- Do not expose to intense light
- Like other direct positive collodion images, supply in a sealed package
Here is an example of a pannotype that was
transferred onto leather:
