I forgot the Birmingham Snow Hill BT Tower

As I walked through the dark and spooky tunnels by Newhall Street canal locks, I found myself at the foot of the 152 metre Birmingham BT Tower which I can see from my kitchen window

the coloured lights on the dishes were added in 2003

The picture badly needed the gamma correction in IrfanView

gamma See gamma correction

A correction to the contrast of images and displays, performed by either software or hardware, and designed to correct for the fact that the intensity displayed on a cathode-ray tube is not linearly related to the input voltage.
