Ladybower x2.5 vertical exaggeration

04 Aug 2007 1 241
I'm always interested in viewing landscapes in different ways and occasionally I experiment with exaggerating the vertical scale of my photos. I'm not sure of the validity of this as a photography technique or an art-form, but I do quite like the effect it produces and quite often this enhances geological and geomorphological features, and so is useful as a teaching aid. This is a view of Ladybower Reservoir taken from Bamford Edge in the Peak District. Here, the River Derwent has cut down through the Namurian ('Millstone Grit') succession - mainly Kinderscout Grit and the Shale Grit (an unfortunate name). The hillsides plunge straight down into the water, clearly showing how these are drowned valleys. Less obvious in a normal view, but brought out by this exaggerated scale is the relative flatness of the tops of the hills, above the 'V'-shaped notch of the valleys. This indicates a much earlier uplifted erosion surface (probably Tertiary age) on which the proto-Derwent and other rivers became established. The stepped topography of the hillsides is due to the presence of alternating hard sandstones and softer shales.

Overdale and Bradwell x3 vertical exaggeration

This view is from Bamford Edge in the Peak District looking to the south west. On the left, the Namurian ('Millstone Grit') succession of Abney Moor, Shatton and Overdale contrasts with the older Dinantian (Carboniferous Limestone) landform to the right. Bradwell village nestles in the valley in between. The easterly (left) dip of the rocks is well seen, as is the stepped topography of Shatton and Abney Moor due to the presence of alternating hard sandstones and softer shales.
