Fibonacci

I really like the geometry of the bishop’s weed’s inflorescence. The arrangement of the umbels in the best Fibonacci manner and the flowers of the individual umbels again completely aligned according to this universal rule. The whole thing reminds me of a galaxy and fascinates me by the fact that the small follows the same rules as the large and somehow everything is connected by it.

While working on the bishop’s weed series, I remembered a picture I took from a carline thistle during an alpine hike that year. In spring one finds the remains of last year’s inflorescences. The flowers long since blown away by the wind, but their arrangement is still perfectly recognizable: in the finest Fibonacci manner. Second motif for this project.

Cyanotype involves coating paper with a solution of green ammonium iron citrate and potassium hexacyanidoferrate and then drying it. This makes the paper photosensitive. The desired motif is then placed on the paper as a negative and the whole thing is exposed to the sun for a few minutes. Afterwards, everything is washed out with water and the motif appears in the characteristic blue tone called Berlin or Prussian Blue.
