Cross-bedded Permian sandstone on the beach at Corrie, Arran. These are a famous feature in geological study. The stratified lines are the remains of downslopes of wind-blown sand dunes from around 260 million years ago when the super continent was a dry desert situated on the equator.

Scale Down

This was one of the questions originally posed: 'How should D800 landscapes be sharpened and scaled down for small-size web use?' Until now we have employed the methods provided by either Juza (www.juzaphoto.com) or Philip Perold (www.philipperold.com). The rider to the question was whether the scaling from the larger D800 image required any additional steps in the incremental scaling these methods employ. Both methods use incremental scaling twice with inter-stage sharpening. Perold goes much further with luminosity masks and Find Edge moves, indeed his code runs to 49 pages and 2,165 lines. Despite this, the action was completed in 6 seconds on a D800 image. His final flourish is to enhance the saturation and add a little glow to overcome the loss of sparkle brought on by the downscaling.

We found this to provide an attractive finish to a 720 pixel image for the web and the method is certainly worth more exploration.

Getting There

One reason the Mull of Kintyre is so quiet is that the journey is very long even though the scenery is amazing. Paul Gallagher gets around this by driving to Ardrossan (to the south of Glasgow in Ayrshire) and then hopping to Arran, then to Kintyre. In total this saves about 100 miles of narrow roads but has the advantage of your arriving at your destination by boat, always a magical experience. The Calmac Hopscotch ticket is about £60 for a car and passenger, depending upon season, number of passengers, etc, so it won't break the bank!
