Here are the promised Cyanotypes. Two trees found on our walk throught the city.
The first one still need some work. Another version with a better coating is drying currently…
This time I didn't scan these two but used my camera. It's a bit easier to get decent colours, but esp. on the second one you see, that even lightning is a problem (using indirect flash). Further you have some distortion because the censor wasn't parallel to the Cyanotype, but that's very easy to correct using hugin (a stitching program).
As usual these (will) have been posted to flickr as well.
great work!! very inspiring to a cyanotype beginner such as myself...i am a screenprinterin byron bay australia & am keen to get going with is process...screenprinting is great fun but making & storing screen can be a bit tiresome..i ahve been looking for a quicker way of working with the images i am producing - & i have found it!.....a couple of questions: will brown ferric ammonium citrate give a brown-toned print?....is it possible to print a cyanotype on glass?...i do glass etching also (see my ebay store,:www.stores.ebay.com.au/adlington-art... no website/blog as yet), & can see great potential in blue glass prints - perhpas if the glass is sandblasted first, then sprayed with matt varnish to give the chemical someting to grip on might work??....am looking forwards to seeing more of your images...

Thanks a lot!
The only difference of brown ferric ammonium citrate is the iron content. It won't give brown prints but it is reported, that the brown version is less sensitive to light.
For printing on glass I'd try to coat the glass with a seizing agent like arrow root starch first. It might be a problem that the arrow root starch coat washes of as well on processing...
