Cyanotype Photography
Cyanotype Photography
Cyanotype photography was one of the first ever photographic
methods. It was first used in the 1840’s by a lady named Anna Atkins, who famously
recorded images of plants. The method works when a special sun-sensitive
chemical is added to paper. When that chemical comes into contact with
sunlight, it turns dark blue. Any objects put on top of the paper are blocking
out the light, so that part of the paper will remain white. The chemical
reaction stops taking place once the paper comes into contact with water and
the chemicals are washed away.
Instructions:
1.
Select some FLAT objects that you wish
to print and see the outline of. For example- weeds, leaves, keys, string,
lace, shell, buttons, cut-outs, paperclips,
and photo negatives.
2.
Remove a piece of paper from the packet.
Place it inside a clear plastic sleeve. Place the objects on top of the
sunprint paper .
3.
QUICKLY expose the paper and objects in
the sun for about 2 minutes until the paper turns light blue.
4.
Now QUICKLY hide the paper from any more
exposure of light and soak in a container of tap water for about 1 minute.
And here are the results - well done year 8!
