Equipment Booking

I have booked us some equipment. We are taking it out next Monday at 4. We have organised where to meet and have made sure we have the paperwork we need to make sure the shoot runs smoothly. As it is getting dark early these days we are going to film a short scene as the sun goes down (I think the lighting will look great) and then once it's dark, we will film the bits we need to indoors. I'm a bit nervous but think that once we get going it will give us a good idea of what ele we need to do...
