[alt-photo] Re: paper and cyanotype

[Loris Medici]

I can imagine / empathize with your frustration! Only after days of
struggle (in 2003) I remembered reading Christopher James'
recommendation / method of exposing bone dry paper (done thoroughly,
with a hairdryer set to the max. temperature), and that saved my life
- what a relief! Post humidification still stays as a viable
(optional) method; one may get few more steps in the highlights...

Very interesting indeed (< 2 mins. exposure), that's in the park of
gum exposures! Never experienced anything like this. Unfortunately
Buxton and the other / new Herschel paper are both out of my scope...

Regards,
Loris.

But I find that at school where it is very difficult to be consistent and make students consistent, exposures were all over the board with cyanotype with Weston the fastest and FAEW blown out highlights even with I think 30 minutes. And that was after they had all developed custom curves for the papers! So I don't think it is an exaggeration to say that cyanotype requires utmost consistency to get predictable results.
