Dunnottar Castle

Posted on by

Dunnottar Castle is a ruined medieval fortress located upon a rocky headland on the north-east coast of Scotland, about 2 miles south of Stonehaven. The current ruins date from the 15th and 16th centuries, but there is believed to have been fortification on the site since the Early Middle Ages.

The ruins of the castle are surrounded by steep cliffs that drop to the North Sea, 50 metres (160 ft) below. A narrow strip of land joins the headland to the mainland, with a steep path leading up to the gatehouse.

I made these photos over the course of a couple of hours after the eclipse in March, partly because I know the place well, partly because I was reminded of it by a photo in the local photo-club, and partly because I wanted to reshoot it at greater quality with newer processing techniques. It’s a pity the path down to the shore is so muddy – perhaps I should revisit either in winter or early spring instead.

For the record, the workflow for these is:

  • tripod, SRB ND1000 filter, multiple frames around 8s shutter-speed at source
  • RAW conversion in Photivo
  • HDR panorama in Hugin + enfuse
  • tonemapping in LuminanceHDR
  • post-processing in darktable
  • further post-processing in Gimp:
    • colour toning
    • film emulation (vintage, Ilford Pan-F or Rollei black and white film emulation)
    • wavelet sharpening
  • organization (tagging + metadata) in digiKam
  • bulk resizing with ImageMagick.

Moody Eclipse Photos

Posted on by

I was up early on the morning of March 20th to get to Stonehaven on the coast in time for the solar eclipse.

It’s funny how there was so much discussion as to what filters one should use when shooting the sun: on the one hand, a direct view of the sun’s disc requires special Baader solar filter (approx 23 stops’ filtration); however, when I arrived to see the extent of the clouds, only conventional photographic filters were needed (a mixture of ND1000 and circular polarizer 2-stop filters). And I think the results were all the more dramatic for it, too.

The first of these photos was made using a Centon 500mm mirror lens over 20 years old – from when I bought my first film SLR (a Canon EOS500n – that dates it) It even shows sunspot N 2303 pretty clearly.

The others are with the Sony 55-210mm lens at full stretch instead.

Each image is an HDR of 3 source frames bracketed +/-1EV, converted in photivo, blended in enfuse and worked in darktable.
