WEEKSIX
CYANOTYPES
this week was the paris trip
due to economical reasons
the trip was inaccessable to myself
so Rosy (darkroom tutor)
was lovely enough to organise a work shop
for those like myself
south bound.
camerless images!
the 153 year of process of cyanotypes has not greatly developed
however
the medium has a lot to thank from
technological advancements.
the cyanotype was the first successful method of printing
alternatively.
the modern way of creating an image
is simply printing a digital file
as a negative
on to acetate.
then an layer of
iron salts and potassium ferricyanide
is brushed (much like painting) onto cartridge paper
and allowed to dry.
By securing the acetate negative over the top
the frame is then placed into ultra-voilet light to be exposed.
after an exposure time the images are then left to soak in cold running water
washing off the chemicals
leaving a "prussian blue" image
and then hung to dry.
