I'd say go for the talk. It lasts longer and you might be able to take some photos at the start of the talk.
Thanks, think I'll go to the talk then :)
Excitement level rising...
I really can't decide between the talk and the photoshoot... I can't afford both... as much as I'd like to.
Argh... can anyone who's been to these things before suggest which would be best?
Thanks :)
