Not really a cyanotype

 I fiddled with a photo of a dead hydrangea head in order to produce a resemblance to the real thing which was  an early form of photography. 
'The object is  placed on paper which has been treated with ferric ammonium citrate and potassium ferrocyanide, after which  is then exposed to sunlight and then washed in water, turning the  uncovered areas of the paper  dark blue.'

The process was also known as sun-printing and because it was used to reproduce architectural and engineering drawings it led to the term blueprint.

March 16th was the anniversary of the birth of Anna Atkins (1799-1871) an English botanist who became interested in  cyanotype prints and  used them to produce what was probably the first book with photographic illustrations, on algae, in 1841.  

There's a whole lot of Anna Atkin's beautiful images here plus a couple more of my imitations as extras.

There can't be many words  with two letters 'y'?
