In my experience Arches Aquarelle does not give good Dmax with kallitpe, unless you give it an acid pre-soak.

For a look at my own working procedures for kallitype, see this article. http://www.alternativephotography.co...kallitype.html



I must say I have been underwhelmed by the Arches Aquarelle with the Kallitypes and the Saltprints.

You mention an acid presoak, and I assume that the size or paper base is alkaline. If so , would that have an impact on the cyanotypes as well.
I will try a 3% citric acid pre-soak (I have a lot made up) and see if it makes a difference.

I have read your kallitype article many times and will try the sodium citrate when I can get hold of it.

Thanks to all for the comments
