All good points, koraks.Thiourea toners are (almost without exception) indirect toners. Depth of toning depends on bleaching. Bleaching starts (rather: is initially most noticable) in the highlights. So that requirement is met.
Image tone is determined by the ratio of thiourea : sodium hydroxide in the second/toning bath. More hydroxide gives more chocolate brown tones similar to sulfide toners, less hydroxide gives more yellowish tones.
Combined toning with selenium shifts tones to more purplish; especially attractive is a deep brown toning combined (prior or after; different effects) with selenium toning.
Frankly I see no good reason to resort to sulfide toners with the availability and flexibility of thiourea toners. The latter are IMO vastly superior in all respects.
I like a light toning too. How much gets toned depends on how much you bleach. Most bleach formulas are way too strong and control is impossible. My bleach formula is:I have used other toners... From what I got back then, I remember I thought those don't give me the same tone sulfide gives... I know everything depends on paper and paper developer. In this case, I want a slight warm toning, not archival, and beginning with the highlights only. Not a big shift, and not a brown print.
Do other toners fit?
Thanks.
Well, don't eat it. But thiourea is easy to contain and doesn't fume. So the risk is manageable.Isn't Thiourea also nasty and cancerogenic?
Fomatone is amazing paper. It can be toned with everything. Even Kodak Blue toner (gold toner mix from formula) gives amazing chalky blue color. I've done combination toning and Fomatone responds with everything. It's a great paper without any toner.Hi markbau, thanks for that!
Yes, for a slight warm higlights toning, we need at least some neutrality, or that warmth just can't be seen. That's why Kenna uses MG Classic that much.
I want to try -also- what fomatone can do when it's developed for a more neutral tone than it's usual. Yet I don't know if it will go beyond the first tests...
Bob Carnie is such a great printer and such a great person and teacher!
I just wrote down those 4/4/1.25, thanks again!

That’s interesting because every warm paper I’ve tried my toning with just goes all over brown even with very short bleach times. I’ll have to get my hands on some. Is Kodak blue a bleach and redevelop? Does it start at the highlights or the shadows?Fomatone is amazing paper. It can be toned with everything.

Kodak T-26, uses Gold chloride, thiourea, and a couple other ingredients. I've found it lasts a long time, back in the day, Kodak understated, IMHO, the capacity. It's not cheap, but gold chloride solution is available on Ebay, or you can buy 1 gram ampules of the Auric chloride crystals. People should try gold toning at least to see the results.That’s interesting because every warm paper I’ve tried my toning with just goes all over brown even with very short bleach times.

Unfortunately, I don' have extensive experience with it but I successfully prepared a 2% solution and direct-toned with it for 8 minutes to warm the image tone.works similarly to toning in Viradon.@RalphLambrecht: I've been avoiding using Sulfides due to smell, toxicity and fogging scares. Black salt is a more attractive alternative if it does work. Can you give more details of your black salt based toning process?
