Struggling with (new) cyanotype toning

[koraks]

I’m personally most intrigued by the deep brick red as found in the complex toner. [...]

[edit] example posted is from @fgorga’s article and not my own work.

Being in the lucky possession of one of @fgorga's actual prints, I can say that the brick-red/brown hue in real life is even more vivid than how it appears here on my monitor. It's quite compelling, really. I've only tried cuprotypes once and ended up with a much weaker/flat result, btw. I understand there are generally speaking two approaches to the process: @fgorga's approach as documented e.g. here on the forum but also here https://www.alternativephotography.com/cuprotype-process/
And then there's the process as described in the 1970s by Patterson's and that was reproduced some 20 years ago by @Cor : https://web.archive.org/web/20070923010637/http://silverghost.stanford.edu/copper/index.html

Well.. there are at least three. Each has its merits and limitations. Here is a versatile process by Jim Patterson:

CUPROTYPE

CUPROTYPE: a photographic print of reddish brown Copper II Ferrocyanide (Hatchett’s Brown) pigment on paper.

There're some supposedly new but yet unpublished processes whose results I've seen only on Facebook. Fortunately, these new processes are appearing in a new book on Cuprotype written by Vincenzo Caniparoli.

I had time to try a couple more yesterday. Super excited for this option going forward.

Very nice prints. What are we looking at? Tannin toned cyanotypes?

What paper are you using?

Ah I think context is upthread a couple posts. These are all bleached back in sodium carbonate until it just starts to hit the blacks (10-15min), then toned back with tannic acid for 50-60min.

Yes, there was talk about cuprotypes, but that didn't seem right.

I think they are beautiful. The tone is useful for many subjects.

So easy to get distracted
