English: Demonstration of capabilities of Twibright Registrator. On a hazy day in Zurich, horizon was photographed 1004 times and registered with Twbright Registrator, a free software for image registration and related tasks. The output was then processed with a special algorithm shipped with Twibright Registrator, which tries to calibrate white and black points locally, adapting to varying degrees of haze throughout the picture. In the result, the distant Alps can be seen, although they are tens of kilometers into the haze.
