Here's another example of getting in amongst the action instead of backing off. I always try to get in close for the confetti throwing - it gives the viewer a much better feeling of "being there".
In this particular shot I like the arms coming in from the left hand side and the brightly coloured petals that are right up close to the lens. And obviously Ruth's reaction is fantastic.
The only problem with getting this close is that I end up shaking bits of confetti out of my camera bag for the rest of the day!
