Thanks Neil,
Just used the photomerge in CS3 seems to get better results.
I used to use Canons Photostitch but it always seemed to require a lot of fine fixing afterwards. With CS3 it appears to sort out the blending giving it a much more even lighting
Mike, It was a fog bank coming in from the north sea. And I dont think it would be fair to start removing from what was actually there. The unfortunate thing is, these spotlights at the foot of the rail bridge catch everything.........
