	Hogsmill Walk Kingston on Thames, London, Saturday 22 Jan 2011
	As well as this single image taken with a 16mm (full-frame), I also made a slightly wider version as a two-image panorama: This version of the panorama uses the Vedutismo projection, which avoids the excessive stretching of rectilinear projection while giving a result without the obvious curving of a cylindrical perspective. All straight lines through the centre of the panorama remain straight. Although used in some 18th century painting this projection was apparently forgotten until it was recently rediscovered by open-source software developers who tried succesfully to 'reverse engineer' their wide-angle Vedutismo paintings. The researchers named it the 'Panini' projection, after the artist Gian Paolo Pannini who is thought to have used it in his paintings. They made it first available at the end of 2008, but in a more general form allowing at the start of 2010 which allows variable moderation of the curvature of straight lines, particularly useful for those near the top and bottom centre of an image. The painters just painted them straight when it mattered. .
	The bridge, close to the mouth of the river is one of the oldest around, though much altered over the years You see this incredible tower from the walk, but I had to make a detour to photograph it more closely Kingston is still the country town of Surrey, despite no longer being in Surrey. The architect of this remarkable building was the Surrey County Surveyor Charles Henry Howell and it was completed in 1893
