www.derelictlondon.com – an extraordinary collection of images by photographer Paul Talling showing the “hidden underbelly” of London.

Shown here at Salisbury Cathedral, this group of figures carved by artist Robert Koenig are ending a journey taken by his mother in 1942 from Poland to the German Nazi slave labour camps and on to the UK where she settled. More of my cathedral shots here.

Rising 170 metres (557 feet) above Portsmouth harbour, the elegant and sculptural Spinnaker Tower was inspired by the shape of a sail. Building costs totalled just over 35 million pounds. In the first shot below, the black rectangle at the top is the largest glass floor in Europe. More of my Portsmouth photos here.

A photographer’s blog with no images, only words describing the photographs he did not take. Missed opportunities with no camera, or occasions where he was not brave enough to click the shutter. Vivid and often poignant, www.unphotographable.com.

Added some shots taken at the wartime codebreaking establishment Bletchley Park to my main gallery here.

Looking like something captured by an endoscope, it’s actually just half a lemon (with a bit of processing in Paint Shop Pro).
