Near-infrared photo of a wooden fence at Farndon Fields, in Market Harborough, England. At the bottom of the fence is a discarded Pedestrian Walkway sign.
The photo was taken using a fisheye lens with a Lee 182 light red lighting gel on a camera sensitive to infrared light. Colours were then adjusted when processing the image. It is impossible to have a true colour infrared photo since our eyes cannot see infrared light.
