Painting with Developer

As I mentioned a few days ago, I am currently looking into the production of ferric oxalate, not because I am dissatisfied with Bostick&Sullivan's product, but merely out of a thirst for knowledge.
I do not know the recipe of B&S, presumably it is iron(III)-nitrate and oxalic acid.
In my first attempt I followed the recipe of Pizzighelli and Hübl (ferric hydrate and oxalic acid). An interesting alternative, but time-consuming.
In the second attempt, it was iron(III)-nitrate and oxalic acid. The time required is similar, but with fewer steps.
The substance is not clearly defined, which makes it difficult to determine the exact content of oxalate solutions. The prevailing opinion is that the solution for the platinum process should contain 27% iron(III)-oxalate, for the Kallitypy 20%.
For practical purposes, the determination method using the specific gravity is sufficiently accurate, although any free oxalic acid present cannot be determined.
For the Kallitype, a specific gravity of 1.13 results in a solution of about 20%; for the comparison of the mode of action, the three oxalate solutions were brought to exactly this value. The measurement of the pH value showed clear deviations between the (acidic) solutions, which indicates different contents of free oxalic acid.

To obtain comparable densities, different exposure times were necessary.
From left to right:
B&S 3 minutes, P&H 2:30 minutes, Ox (iron nitrate) 2:15 minutes.
Wie schon vor einigen Tagen erwähnt, beschäftige ich mich momentan mit der Herstellung von Eisen(III)-Oxalat, nicht weil ich mit dem Produkt von Bostick&Sullivan unzufrieden wäre, sondern lediglich aus Wissensdrang.
Die Rezeptur von B&S ist mir nicht bekannt, vermutlich handelt es sich um Eisen(III)-Nitrat und Oxalsäure.
Bei meinem ersten Versuch bin ich nach der Rezeptur von Pizzighelli und Hübl (Eisen(III)-Hydrat und Oxalsäure) vorgegangen. Eine interessante Alternative, doch der Zeitaufwand ist hoch.
Beim zweiten Versuch waren es Eisen(III)-Nitrat und Oxalsäure. Der zeitliche Aufwand ist ähnlich hoch, allerdings bei weniger Arbeitsschritten.
Die Substanz ist nicht klar definiert, was es schwierig macht, den exakten Gehalt von Oxalat-Lösungen zu bestimmen. Nach vorherrschender Auffassung sollte die Lösung für den Platinprozeß 27% Eisen(III)-Oxalat enthalten, für die Kallitypie 20%.
Für die Praxis ist die Bestimmungsmethode über das spezifische Gewicht hinreichend genau, wobei allerdings ein eventuell vorhandener Anteil an freier Oxalsäure nicht festgestellt werden kann.
Für die Kallitype ergibt sich bei einem spezifischen Gewicht von 1.13 eine etwa 20% Lösung, für den Vergleich der Wirkungsweise wurden die drei Oxalatlösungen auf exakt diesen Wert gebracht. Die Messung des pH-Wertes zeigte deutliche Abweichungen zwischen den (sauren) Lösungen, was auf unterschiedlichen Gehalt an freier Oxalsäure hindeutet.

Much has already been said and written about Little C. See the previous post for a little sample.
The style of the building complex can partly be traced back to the inherent cynicism of the project developers that created a project that uses the morphology of ultimately very problematic urban districts/housing complexes like The Projects (New York) -and the long ago demolished Kowloon (Hong Kong) quarter.
This is for now the last of the Little C mini-series.

From Wikipedia: Arctium is a genus of biennial plants commonly known as burdock, family Asteraceae. Native to Europe and Asia, several species have been widely introduced worldwide. Burdock's clinging properties, in addition to providing an excellent mechanism for seed dispersal, led to the invention of the hook and loop fastener. (That's Velcro to you and me!)
Arctium species generally flower from July through October. Burdock flowers provide essential pollen and nectar for honeybees around August, when clover is on the wane and before the goldenrod starts to bloom.
*** So as these have yet to turn into their summer green a monochrome treatment seemed appropriate. ***

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.

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.

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.

I really like my new purchase. It's built like a tank (weighs like one too), built in bellows for macro shots, interchangable lens system, multi-exposure and looks so darn cool.
About the shot - Double exposure and processed in LightRoom. Shoot on Lucky 100 film.
This is also self-developed with Ilford developer and fixer.

Every time I come to San Francisco, there is some kind of smart-ass billboard along the highway ... "ask your developer," it says.
Ask her what? Whether Twilio is better than some other provider? Whether the cloud is here to stay? Who comes up with these crazy signs?
Fortunately, it doesn't matter very much ... by the time I come back again, this billboard will have been replaced by something else just as mysterious.

************************
In early November 2015, I flew from New York to San Francisco to take a weekend street-photography workshop under the tutelage of Eric Kim. As you might expect, I took gazillions of photos; but not all of them were specifically associated with the workshop itself. On the way out to San Francisco, I took a bunch of pictures with my iPhone; and during the weekend, I took a number of photos that had little or nothing to do with street-photography per se.
I’ll upload the photos in dribs and drabs during the next several days, and let you decide which ones are sufficiently interesting to warrant a second look…
I've tested 9 programs for the purpose of processing challenging nightscapes and for preparing images for time-lapses.

The ingredients required for making enough Caffenol-C for the development of ten 120 films
The developer mixture described below seems to work with both black and white films (gives, obviously, black and white negs) and for colour films films that normally require a C-41 process (which results in a copper-toned negative. Note that Caffenol-C does not work for old colour films that require a C-22 process...

========================================
CAFFENOL-C
Standard receipe, taken from various sources on the net.
INGREDIENTS:
Instant Coffee (not decaf)
Washing Soda (Sodium carbonate, Na2CO3)
Ascorbic Acid Powder (Vitamin C)
Dishwashing liquid
FORMULA
12oz water
3 1/2 teaspoons washing soda (Sodium carbonate, Na2CO3)
1/2 teaspoon ascorbic acid
PREMIXED INGREDIENTS
Premix solutions can be set up. But do not premix the whole developer as it (reputedly) has a short shelf-life. For ease, create premix solutions of required strength for each of three developer ingredients so that in the end all that needs to be done is to mix equal amounts of each of the three premixes
Strength for premixes:
Instant Coffee: 10 teaspoons / 12 oz
Washing Soda: 7 teaspoons / 12 oz
Ascorbic acid:1 teaspoons / 12 oz
when ready to develop, mix required quantity in three even parts.
Small Patterson Tank
120mm roll film requires 550 ml (20 oz)--ie 3 x 7 oz for the development of a roll of 120 film (which gives 21 oz, but makes life easier).
