Double
- Multiple Exposure photograms
While many photograms are made simply with one exposure
onto the sensitive paper, a much more abstract and layered
effect can be obtained by exposing the objects once, rearranging
them and then exposing them again.
Tonal variation somewhat like posteraization
can be produced by using one exposure for a time much less
than the other exposure.
Different
light sources and directions of light can be used for the
two or more exposures.
The
adjacent image is a section of a photogram that has
been made with a double exposure. Laying the objects
on the paper exposing it and then laying a different
set of objects on the paper to obtain the final image.
The section at the bottom of the image is an over
lay of a snuff horn and a piece of carved ivory used
to back a set of playing cards. The long area that
takes up the rest of the image is a combination of
a glass bottle with the word AUCKLAND embossed on
it, a feather and a pestle.
For
many of my projects I have used double exposure photograms
to reference the idea of layers.

to Coda a project on landscape and implements
with black & white photograms. After the photogram
has been made the G Clamp has been laid on the paper
and the rest of the paper exposed to light creating
a cut out of the clamp with the photogram texture.

Evidence
from the Religion of Technology a project exploring
technology as a religion with colour negative paper
photograms.
With double exposure
colour photograms the colour filtration can be dramatically
altered between exposures giving some objects a
predominantly yellow cast and others a predominantly
magenta cast. |
