Problems I have faced ... Before the music video shoot!!

I haven't even officially started filming my music video yet and have already come across some problems.

We are very lucky to have five Cameras, although my class of nine needs to share it with the AS media class (as they're needing the camera's to shoot for their magazines). The issues I have faced is sorting out to book the camera on specific days ... however they've already either been booked out by the other class or a pupil from my class. Also as we only have one white back drop and set of lights these also need to be shared between my media class and the AS media class, this is very tricky and complicated as the classes have different teachers, so it is first come first serve.
