Thanks for the comments guys. I'm thinking I'm going to get it printed out for the parents, apparently they've never been able to get a shot of him smiling.
Here is some EXIF info:
50mm
f - 1.8
1/160 sec
ISO 800
The colour one is pretty good, the blurred background has some nice soft colours in it, but I thought I'd try it as a black & white and I like the way it has turned out. I'll post the colour version shortly
No flash either, just available light in a community hall.
