I shot a music video for a friend last week. We had no time, but decided to do "just something". We went outside in the dark with my 60D and the nifty fifty and came back an hour later with our footage. We hadn't planned anything. It's was just a collection of random shots. I edited the video in Final Cut Pro X in 4-5 hours and that was it! It's not perfect, but considering we only had that one hour, I'm happy.
I love how Canon has enabled us to work fast. Just go out there and get the shots.
