River Manifold at Ilam

In drier weather part of ithe Manifold runs underground but this section, near Ilam Hall, flows all year. This shot was taken with a Canon compact camera which had its infrared blocking filter replaced with one with a roll-off around 720 nm. The colours have been modified by inverting the A and B colour components.
