If you really want to capture a snapshot of your highschool you wont be able to do it in one take. You will need to film random bits throughout the schhol, day, week etc to really capture what you need to refect you point.
Observing the world through a lens gives you a totally different perspective, a vantage point
I would suggest you film as much as you can...watch it all, then incorporate what you wish to convey into these images with your editing. Your walkthrough dialogue will be much more poiniant (sp?) if the images compliment the words.

have fun void. Sounds like you have a great idea and it would be interesting to see the finished product.



btw, I like scarletts angle as well. It kinda forces the viewer to reflect and think, to challenge themselves.
peace.
