The original cyanometer was invented by the Genevan physicist and Alpine explorer Horace-Bénédict de Saussure (* 17 February 1740 in Conches; † 22 January 1799) in 1789. It is an instrument for measuring 'blueness', specifically the colour intensity of blue sky. With the measurement it is possible to draw conclusions from the constitution of the atmosphere: the bluer the sky the less the water vapor. Saussures cyanometer consisted out of 53 parts of a circular ring ranging from white over different grades of blue to black (Saussure used Prussian blue). Saussure used his cyanometer for measurements in Geneva, Chamonix und on the Mont Blanc. Alexander von Humboldt used a cyanometer on his expedition to America (1799 - 1804). You can use our Cyanometer in three modes: The modern scale uses distinct grades of blue starting with clear white up to black. The Saussure scale shall give an idea about the colors from Saussures original cyanometer. With the user defined scale own scans of blue skies can be added to an own colored circular ring - an own cyanometer. Each scan is saved inside the app containing information about date, time and locality. So it is possible to compare scans of blue skies from different locations.

Works, but is very basic. Being an interactive computer program it would be obvious to give the approximate humidity of the atmosphere due to the Mie scattering compared to the time of day. This would make this a much more useful tool for photographers looking to use polarizers and painters wanting to mix paint and for amateur metrologists comparing to measurements.

It would be needed that the saved image is not on my photos but in the app itself or at least automatically create an album on photos of “my skies”. Also would be needed that the saved image includes the ring and labels which is visible as such when accessing “my skies” instead of the default sky picture, otherwise the data that is stored makes not much sense without the reference sky image.

I love this app. Since reading about Humboldt’s Cyanometer in “The Invention of Nature” I’ve been a bit obsessed with the idea of measuring the blueness of the sky. I understand the blueness can be a measure of water content, but there is something also poetic and uniting about the cyanometer: we all share the same sky, yet it is for each of us a different sky. Use this app and your sky will never be simply blue again.
