Hmmmm.. I would bet this is where I probably have gone wrong in the past. How do I know which is which? Shirts, credentials?
Basically, yes. VIP badge holders are allowed digital cameras... but they aren't allowed to shoot video. There are a few people in the past who have been with bands (and some of the bands on the same label or management), and they've videoed "their bands". I followed up on a few cases, but not only were they not filming other bands, they weren't even interested in watching them. So there are exceptions.
To be clear, someone else doing something, allowed or not, does not waive the policy for anyone else. If you haven't been granted explicit permission, then you're not allowed to bring in a digital camera or record anything.
Sorry if there's confusion on who is allowed and who is not - I know exactly where you're coming from. It'd be nice for all those special cases to wear a big yellow shirt or something, but that's probably not fair to them.
