First know that we are total rubes. We began our business almost exactly 1 year ago today with zero training. It began as a favor for one couple done with 3 cheap camcorders... then another, and another.
We've shot seven weddings now and will keep working to get better. For now, our business motto is..."we're much better than your uncle." We shoot 3 cameras (Canon T3i/600D).
We usually deliver 2 or 3 videos. Here is the (almost) finished 9 minuter from this January up here in the frozen wasteland. For context, it was about zero degrees (Farenheit) for the outdoor shots.
The only thing I see we do that I don't see from you folks is offer a photographers backdrop as an add-on. After the dance starts (typical is a dinner followed by a 3/4 hour dance), we'll set up and shoot for 90 minutes. We then turn the pics into a stop motion, and share the photos on Facebook.
