Thingvellir

Submitted by Jürgen Tenckhoff on Wed, 01/27/2021 - 14:56

The place Þingvellir or Thingvellir has a special meaning for two reasons: One is geological. because one is here in a rift zone at the boundary between two tectonic plates. On the other hand, one of the oldest parliaments in the world met here. Since about the year 930, the traditional Althing assemblies have been held annually in Thingvellir, which have both legislative and judicial functions.

The place impresses with the high basalt rocks and its waterfalls. It is not far from the capital Reykjavík.

Lighthouses and endless expanses

The Westerheven lighthouse can only be reached on foot or by bike. It is about 1 km from the outer dike towards the lake and has become a popular photo motif thanks to its two symmetrical houses.

This post mainly shows it from the outer dike. It made sense to use different focal lengths (Nikkor 24-70 mm / f / 2.8 and Nikkor 70-200mm f / 2.8) and to create a small series of comparisons for the image size depending on the focal length

The Hallig world in North Frisia

Submitted by Jürgen Tenckhoff on Fri, 10/30/2020 - 11:59

The ten German Halligen are grouped in a circle around the island of Pellworm. These "young" islands only exist in the North Frisian Wadden Sea. Their land masses protrude a few meters from the sea and are regularly flooded by strong floods (colloquial: "Landunter"). Their residents live in houses on artificial embankments, the terps. These are high enough to withstand "normal" storm surges.

Photo technique: "Infrared + camera conversion"

Submitted by Jürgen Tenckhoff on Sun, 06/30/2013 - 20:32
To understand the peculiarities of infrared photography, i.e. a process for recording invisible light, let us first consider a few aspects that are important for recording visible light. Only a narrow range of electromagnetic waves can be detected by our (healthy) eyes. It ranges from red (750 nm) to violet (400 nm). Depending on the location, day and season, there are differences in the distribution of the individual wavelength components in the perceived light. If the reddish parts predominate, the light is perceived as warmer, and the bluish parts predominate, resulting in a cooler color mood.
