It's fair to say that these pix are not exactly the sharpest I've taken.
However, as you will see, some of the backgrounds are quite sharp despite the poor light:
Mark's and Robin's fuzziness is mainly due to the fact that they move about a lot - and I can't blame them for that!
I've included the pix because you can get a real sense of motion by downloading them and
running them one after the other in, for example, Windows pix and fax viewer.
