After a bleach containing bromide and subsequent redevelopment, the silver particles have a coarser structure, which allows selenium toning without the usual fading to unattractive yellowish colour of Kallitypes.

A later iron toning, however, does not produce a clearly recognisable split tone as with silver gelatine prints, but a continuous greenish tone due to the addition of the two colours red and cyan.

A following lead toning changes this only slightly, at least cyan is reduced, which leads to a warmer impression.

‘Espresso’ is a cultivar of Geranium maculatum native to North America.

The fire red flowers of Indian Paintbrush (Castilleja sp.) contrast with the blue hues of Lupin flowers (Lupinus polyphyllus) that are defocused in the background.

Indian Paintbrush plants are partially parasitic (hemiparasitic) on the roots of other plants such as grasses. They also have the ability to concentrate high levels of selenium in their tissues from the soil and can be toxic if the roots or shoots are consumed.

For more information see: en.wikipedia.org/wiki/Castilleja

In order to be able to use "normal" selenium toners (which contain Ammonium salts and/or Thiosulfate) for Lobotypes and Kallitypes without the usual fading and yellowing of tones, the print should be bleached (potassium ferricyanide and bromide) and redeveloped in any developer for gelatine silver prints.

 

The toning target was a split tone with subtle reddish shadows and bluish highlights.

The same toner combination as the previous image, but this time with Ilford Classic. This paper reacts considerably slower to both toners, so colour saturation is lower when bleaching is relatively short.

In the coloured development with lith and sienna (glycine), highlights and mid-tones come out reddish yellow and the shadows slightly greenish. If this shade colour is not desired, it can be toned briefly in selenium. Because polychrome prints react to selenium toner with a clear increase in density, the toner should be diluted at least 1+20 and toned for no longer than one minute. With longer toning times the hue shifts towards magenta, but in such cases it is necessary to print considerably lighter, because otherwise the differentiation of the tonal values suffers due to an enormous increase in density.

For me, the real advantage of this development method is not so much the more variable colouring, but the possibility to show the lower mid-tones brighter than usual, in addition to a narrow band of deep shadow densities.

After selenium toning, this effect recedes a little because the colour contrast also contributes to the separation of the tonal values.

 

Bei der farbigen Entwicklung mit Lith und Siena (Glycin) kommen Lichter und Mitten rötlich gelb und die Schatten leicht grünlich. Ist diese Schattenfarbe nicht erwünscht, kann kurz in Selen getont werden. Weil Polychrome Prints mit einer deutlichen Dichtezunahme auf Selentoner reagieren, sollte der Toner mindestens 1+20 verdünnt werden und nicht länger als eine Minute getont werden. Bei längeren Tonungszeiten verschiebt sich der Ton in Richtung Magenta, in solchen Fällen muß jedoch erheblich heller geprintet werden, weil sonst wegen einer enormen Dichtezunahme die Differenzierung der Tonwerte leidet.

Der wirkliche Vorteil dieses Entwicklungsverfahrens ist für mich, nicht so sehr die variablere Farbgebung, sondern die Möglichkeit neben einem schmalem Band von tiefen Schattendichten, die unteren Mitteltöne heller darzustellen als üblicherweise.

Nach einer Selentonung geht dieser Effekt ein wenig zurück, weil auch der Farbkontrast zur Trennung der Tonwerte beiträgt.

A developer tuning for subtle light tones. Pretty without toning, I think. However for completion a Selenium toning 1+10 two minutes.

Sepia toner.

The common mallow is part of the large family of Malvaceae plants that include cotton, okra and hibiscus. It is an edible plant that has been used for medicinal care as well as food. The fruits are round and have cheese-like wedges which give the common mallow its nickname, cheese plant. Mallow stems are flexible and come from a central point, often lounging on the ground. This wild edible is used as herbal medicine in a variety of ways. It is an anti-inflammatory, diuretic, demulcent, emollient, laxative and an expectorant.

 

Distinguishing Features

Common mallow is a winter or summer annual or biennial, freely branching at the base, with a prostrate growth habit. It is a low growing weed, with a deep fleshy tap root. The seeds germinate through the summer and broken stems can also root. This plant has stems that originate from a deep tap root and are low spreading with branches that reach from a few centimetres to almost 60 centimetres long.

 

Common Mallow

Flowers

The flowers are borne either singly or in clusters in the leaf axils blooming from June to late autumn. They have 5 petals and are white, pinkish or lilac flowers that measure on average, 1 to 1.5 cm across.

 

Leaves

Common mallow leaves are alternate, on long petioles, circular to kidney-shaped, toothed and shallowly 5-9 lobed, 2-6 cm wide. Short hairs present on upper and lower leaf surfaces, margins and petioles.

 

Height

This plant can grow anywhere from 10 to 60 cm in length.

 

Habitat

The common mallow likes to grow in lawns, gardens, roadsides, waste areas and cropland. It originated in Europe, Asia, and Northern Africa and is also in the Americas and Australia.

 

Edible Parts

All parts of this plant are edible. The leaves can be added to a salad, the fruit can be a substitute for capers and the flowers can be tossed into a salad. When cooked, the leaves create a mucus very similar to okra and can be used as a thickener to soups and stews. The flavour of the leaves is mild. Dried leaves can be used for tea. Mallow roots release a thick mucus when boiled in water. The thick liquid that is created can be beaten to make a meringue-like substitute for egg whites. Common mallow leaves are rich in vitamins A and C as well as calcium, magnesium, potassium, iron and selenium.
