I’m posting this ahead of time to give you the chance to get involved with World Cyanotype Day 2016 on Saturday 24th September.
According to Wikipedia;
Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints. The process uses two chemicals: ammonium iron(III) citrate and potassium ferricyanide.
It’s possible to make cyanotypes at home using some chemicals that are fairly easy to get hold of. Here are a couple of links to articles on how to make a cyanotype;
Have a look for the chemicals on eBay as a starter. Also on eBay (or Amazon) you might find Sunography paper which is paper already impregnated with chemicals and sensitive to light, you just need to select the subject for the print and away you go – I’ve bought some ready to try!
You can also make cyanotype prints from existing photographs by inverting them, printing them onto a transparent sheet and putting that sheet on top of the light sensitive paper.
Of course, you can always cheat in Photoshop;
Why not have a go – I’d love to see what people come up with – I’ll post my efforts in a couple of weeks.
