The River Foss is an improved river in North Yorkshire, England, and a tributary of the River Ouse. It rises at Oulston reservoir at Yearsley and runs south through the Vale of York to York itself, which stands on the confluence between the Ouse and the Foss. Improvement works were promoted by Acts of Parliament in 1793 and 1801 which sought to make the Foss navigable as far as Sheriff Hutton. It is navigable for just over a mile from Monks Bridge (over the A1036 road) to Blue Bridge in the centre of York where it joins the Ouse.

high dynamic range imaging (HDRI) is a set of techniques that allow a far greater dynamic range of exposures (i.e. a large difference between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to the deepest shadows [wikipedia}
