I still think that the best way to try out a new camera is by filming the same stuff of everyday because you never know how some things might happen differently.
During college I took some making-of photos for different kinds of short-films, videos, etc. Here are some examples.
My documentary assignment for university was exploring new places that I’ve never known before. Accidentally I found the snoezelen room. I was very grateful for: not only letting me filming this small room but also being long hours by the company of the people who work and frequent the snoezelen room. When you do a documentary (doesn’t matter if it’s filming, writing or taking photographs etc.) it can be unexpectedly inspiring.
