#7 Today I found myself struggling with a quick construction to capture the reflecting light on the surface of the lake. Under windy and wavy conditions, instead of catching reflections, the cyanotype formed a chromatographic pattern by tipping the water. (cyanotype on cotton 150x200cm) notes: indigo. a value of concentration.                 [...]

#6 Using the station’s UV Spectrophotometer, UV-120-02, Shimadzu I regard the absorbance spectrum of the cyanotype dye. I compare the absorbance value of the dye unexposed and exposed (30min) with no significant results. I assume the chosen duration was too short to state a difference in the absorption rate of the dye. The absorption spectrum [...]

#4 While walking on the trail to the tree country cairn, I stumbled upon a fence marking the boarder between Norway and Finland.  I did not make it to the three-borders-point after. The next day I asked Oula A. Valkeapää about the fence. He explained that it was established after the Napoleon Wars (1809). Later [...]

#2 Sir John Herschel, known for his achievements in astronomy and chemistry, discovered the chemical reaction of the cyanotype in 1842 (1). Initially Herschel explored the cyanotype process in its ability to measure the ultraviolet part of the spectrum. Later this sensitivity to UV-light was employed for scientific instruments, as for example for the Jordan [...]
