Adverts running for a new series ....

Reminded me of a question, What an earth is the camera effect they use on that series which makes most people's face, and especially jamies appear in such soft focus ?

Its really weird, don't think I've seen same effect on anything else, or not used to that degree anyway

Apparently Salma Hayek's in one of these. I can't think of any other reason to bother watching it.
