Been silently observing and taking in info from the forum for a few weeks now. Am going skiing in France in a couple of weeks and am looking for some tips on action shots. I half understand issues about white ballance with regards to snow and the like, but would like a somewhat clarified explanation regarding this. I'm taking a 550d with a 50mm 1.8 prime and a 55-250 canon. This will be taken out on a limited basis due to the fact I'm going for the skiing mainly. On the other hand, I will be taking a Sony DSC TX5 p+s which is waterproof and buffoon proof to an extent, and has some good manual capabilities.
