I had set up and planned this unusual reverse photograph

of the 0H72 12.07 Derby to Wembley light engine move and sat and waited for it for half an hour. However, as can be seen, despite all my planning, it did not work as I had failed to notice that the camera's memory card was full. I managed two 'burst' photographs before the shutter stopped firing with a bleep from the camera! I have included the image of 37884 'Cepheus' as a reminder to always check all the camera's settings prior to pressing the shutter; all others out there to take note too!
