I'm looking to buy a camera for my son to use for stop-motion animation. He has been using an old web cam, but he wants to step up in quality now. What features, eg. live view, resolution, etc, should I be looking for? I've looked at the Hue cameras but I'm not sure these will give the better results we're looking for. Of course, there's a budget, as he is just a teenager – I'd guess we wouldn't want to spend over about £100 at this stage.
