Hello Charles,

great that it works for you! Ive put a little description on my web site on http://fb42.s6.domainkunden.de/kunden/hamann/Cyanotypes/Cyano_Toning.htm. Just added some sentences about changing the color tone with weak alcalis and acids after toning. Seems like this can be a cause for the different results when toning with the same receipe on different locations.

Have a nice day
