[London Lite]

Not living in the London area anymore I don't see ITV News London very often, but when I have seen it I did find the background image slightly distorted, like the image had been made too big. I am guessing the reason for this is when the camera footage was originally captured it was for a far smaller rear projection screen from their old studio. However now in the days of HD it does not look great, but i suppose ITV don't have a camera mounted on the building anymore which could capture the image.

No, they replaced it with recorded footage from before they left the South Bank.
