Taken the other day at Vauxhall while walking to meet my wife for lunch. Wanted to get some movement in the photo. Chose a red london bus because of the colour, to make it contrast against the blue sign. Also to show it was not going to stop on the "Red Route".
Tried various shutter speeds, some too slow and some too fast. Settled on this:
ISO 250 1/30 sec @ F22.
Levels, contrast and saturation tweaked. USM applied.
