Thanks Nandakumar.
I took a series of shots at different Tv settings of this train crossing the bridge.
This was taken at 1/1000sec which was to fast, hence the dark shadows under the bridge.
The next shots taken at slower speeds, brought out more detail under the bridge.
But as soon as the train got an other couple metres further over the bridge the sun hit the silver panels on the train it give off massive glare.
But I have learnt for this particular shot to work I will need a slower shutter speed than 1/1000sec.
When I tried to bring back some detail under the bridge it introduced to much noise.
