Sometimes low light can be your friend

In this shot, taken in a road tunnel in Switzerland, the low light level has lead to motion blur as we drove along generating an interesting sense of motion as a result.

This is one of those cases that reminds me that the camera would be better if it had direct control over shutter speed for those times when that would allow this sort of creative effect to be done deliberately, rather than (as in this shot) – essentially by accident!
