Thermalcities.com looks at the world of thermal imagery on behalf of ordinary people. Set up originally to show how London looked through the lens of a thermal imaging camera, it is now being very slowly revised. The aim now is to show much more about the technology for people who do not wear a uniform. This will include more imagery from others, of the world around us. There will also be much more experimental stuff: ranging from monitor backgrounds based on the thermal images to news on experiments with the technology by scientists and artists.
Thanks to the loan of a thermal imaging camera from  FLIR Systems, Thermalcities has a large pool of decent original thermal images of to present. Thanks also to people associated with: Canary Wharf; Centre Point; London Zoo and Tower Hamlets Town Hall for allowing access to take the pictures. Finally, special thanks are due to The British National Space Centre; Horton Levi Ltd; Hot Mapping Limited and an increasing number of other contributors who have kindly allowed their work to be reproduced on this site, as cited on the relevant pages.

London's Tower Bridge and City Hall, as captured by a thermal imaging camera on a cold, sunny winter day. The Sun's heat is reflected and radiated by the buildings, whilst the cloudless sky is a cold, dark blue.

This picture, purely of detected heat,  comprises several thermal images,  knitted together, to provide a broad field of view.

To the right is a single thermal image of St. Paul's Cathedral, reinterpreted in four different heat-colour spectrums, each of which reveals something slightly different about the heat that can be discerned. This kind of exploration, with buildings, machines, people and images is explored much further throughout the site.

Below is a small sample of the basic 'artistic' and 'curio' thermal images captured during the several days that FLIR Systems were kind enough to lend a camera for.

Another composite, same bridge and time as above, of people gathering for the Millennium Wheel fireworks display at midnight



Another composite of the Millennium Wheel; Thames and Parliament . This was taken on 27 December looking west, using a temperature spectrum that captured the buildings' silhouettes against the fractal patterns of the clouds.
