Photo technique: "Color-key"

Submitted by Jürgen Tenckhoff on Mon, 07/20/2020 - 17:09

In color-key shots, an object of the photo composition is highlighted by making it appear in the original color, while the rest of the image is only shown in shades of gray or black and white. There are several ways to achieve this effect. You can work very precisely with the clipping tools and the layering technology of the photo editing programs Photoshop (Adobe) and Gimp (OpenSource). There are many tutorials that explain the sometimes very complex work steps involved in these programs.


Photo technique: "High Dynamic Range (HDR)"

Submitted by Jürgen Tenckhoff on Sat, 07/11/2020 - 12:15

The HDR display technology is primarily intended to compensate for the restricted dynamic ranges of digital sensors. If subjects have very bright and at the same time very dark areas, the details in the (overexposed) bright and (underexposed) dark areas disappear with a single shot. Just think of the window flooded with daylight, which - when properly lit - makes the surrounding objects disappear in the dark. With HDR technology, multiple shots of a subject with different exposure values ​​are now taken and then offset by software so that the structures are retained in all areas.


Long exposure on the Rio Nava

The Rio Nava flows through the pilgrimage site Santuario de Nossa Senhora da Abadia, whose tributaries with their moss-covered stones offer beautiful motifs for long-term exposures. But some manual work was also necessary here, as autumn had already left many traces in the form of withered leaves and fall wood. It was worth it to expose the beautiful mosses, who were certainly happy about this photo project.

Long exposure at the "Ponte do Nava"

An impressive way of the cross leads from the former camelite monastery and today's pousada Mosteiro Amares to the pilgrimage site of Santuario de Nossa Senhora da Abadia. The beautiful pilgrim cities between mountains also show the origins of the Cistercian monastery in Portugal. Fed by many tributaries, the "Rio Nava" rises here and the swirling waters with their moss-covered stones, the waterfalls or a round bridge, the Ponte do Rio Nava, offer very beautiful motifs for long exposure.

Long exposure: Breitach gorge

Submitted by Jürgen Tenckhoff on Sun, 04/19/2020 - 14:51
After the glacial melt at the end of the Würm ice age, the Breitach cut itself some 150 meters deep into the rock over the past 10,000 years, creating the deepest rock canyon in Central Europe: the Breitach gorge. It runs 2.5 km between the exit of the Kleinwalser valley at Tiefenbach, a district of the municipality of Oberstdorf in Germany, and the Walserschanz in Austria.
