Translating Bacteria Prints to Cyanotypes

Very excited about learning this old fashioned photographic process - using the sun to make contact prints from a "negative".

I've selected some of the bacterial prints, which are typically small on 2, 4 or 6 inch circles... and enlarged these onto transparency material using a photocopier. Then... waiting for a strong sunny day to printed these onto paper i've sensitized. The one above happens to be very dark... others come out much lighter, depending on the strength of the sun and length of exposure time.
