In Morsum one finds a cliff on the northern shore at the border to the Hindenburgdamm, shaped some 120.000 years ago, which is a national geotope. It is a soil structure formed by northern European glaciers with red (limonite), yellowish and white(kaolin) sands. These sands itself had been deposited 7 – 11 million years ago. More detailed information can be found in a Wiki (English oder German).
The image is an HDR of 5 exposures, intentionally overexposed and combined manually and one processed with software (HDR Efex Pro 2). Doing so no traces of a technically generated HDR image are recognizable. The resulting HighKey image looks natural. I adopted this way of processing HDR images from Harold Davis.
