One of my favourite toner combinations for silver gelatine prints is thiourea (MT3 Vario) followed by selenium (MT1). With the new MT17 selenium toner, similar results are now possible with Kallitypes.

It used to be a pub. The Sun Inn offered everything the traveller needed including accommodation and a beer garden behind the building. These days, pubs are being converted into residential homes and developers make sure that the yard behind is turned into accommodation too, rental or other.

Catecholentwickler haben den Nachteil, daß sie als giftig eingestuft sind und als Warnhinweis auf der Flasche ein Totenkopf-Piktogram aufweisen müssen. Auch das Hydrochinon der Lithentwickler ist als gesundheitsschädlich eingestuft. Bei Konzentraten besteht für Anwender allerdings nur eine Gefahr, wenn man das Zeug schluckt oder darin badet. Es macht also eigentlich keinen Sinn, das Catechol aus dem Zweitentwickler nach Lith zu verbannen. Ein Austausch gegen eine ungefährliche Substanz ist möglich, aber nicht ökonomisch. Der Ersatzstoff ist erheblich teurer, im Grunde also eine nutzlose Spielerei. Ein erster Versuch zeigt auch eine etwas kontrastreichere Wirkung, was sich aber noch ändern ließe.

Catechol developers have the disadvantage that they are classified as toxic and must have a skull and crossbones pictogram on the bottle as a warning. The hydroquinone in lith developers is also classified as harmful to health. With concentrates, however, users are only at risk if they swallow the product or bathe in it. It therefore makes no sense to ban catechol from the second developer after lith. Replacing it with a harmless substance is possible, but not economical. The substitute substance is considerably more expensive, so it is basically a useless gimmick. A first attempt also shows a somewhat higher-contrast effect, but this could still be changed.

Before I give the credits to the developer let me first apologize to those who have followed me up to this point. my activity in the last 6 months has been minimal due to a horrible laptop. the other day I fixed that in buying myself a new computer, so I'm hoping that I'll be able to take more ambitious photography than ever. my inactivity got me unfollowed by countless members, and banned from multiple groups, so you can imagine I wont be doing that again :)
This lovely landscape was on my list for some time, I had seen it briefly on my old computer but there was no hope of capturing it before. not quite the WL I was looking for, but all my choice WL's are saved on my other computer. (side not if anyone knows how to convert a WL to file and transfer it, paint me interested and in turn, my windlights would be up for grabs to anyone interested.) I'll certainly have to be back or to one of their many other, equally beautiful sims when I get my WL's sorted.

The sodium acetate developer produces the coolest image tone in Kallitype.
One or the other user may well have doubts about this. If the results are not as cool as expected, this is not due to the developer but to the workflow. A really cool tone is only maintained if the print does not come into contact with tap water before fixing. If the print is rinsed with tap water after the developer or the clearing bath, the image tone will be significantly warmer. It is not a question of which shade is perceived as more pleasant, but rather an advantage to know how to control the colourfulness.
For toning before fixing (platinum, palladium, gold), a rinse cycle is advisable in order not to change the property of the toner by introduced acid. For all tonings after fixing, a cooler initial print has the advantage of a higher maximum blackening. This is not decisive for successful toning, but differences in hue and saturation become apparent.

A coworker and I went to see the Valley of Fire State Park for an afternoon. The park is a 1h drive north-east of Las Vegas, Nevada. He is our star developer, who is very productive, and comes up with creative ideas. I took this shot with his Xiaomi Redmi 5 mobile phone.
I processed a photographic and a paintery HDR photo from a single mobile phone exposure, merged them selectively, and carefully adjusted the color balance and curves. I welcome and appreciate constructive feedback.

Here you can see how early car manufacturers used lead (instead of Bondo) to fill in roof joints. Notice how sanding (file) marks are still present in the lead. More importantly, just how thick the early paint jobs had to be to cover these scratches up.

Beginners in the technique of Kallitype often ask which developer they should choose.
Only a comparison of colour and tonal values with identical exposure time. To achieve the same level of blackness with the acetate developer, the exposure time would have to be slightly longer.
