I send the film cartridge to Pro8MM in California. They transfer the film to miniDV for me.
I guess it's not really noticeable on the internet but on television you can really see the difference between the sharp dv shots and the grainy film shots.
The low light issue is a major concern. As you noticed everything was outside in the daylight. We did shoot some stuff inside the church (which was the last shot in the montage) and at the reception, but I didn't feel it was good enough quality to end up in the finished product. I would have had to crank up a 150 watt light to shoot inside of the reception venue and there ain't no way I'm doing that. I try to shoot with as little light as possible.
To purchase and process 4 reels of film it costs $200.
How do you handle the film in post? Audio [<- Correction: I meant "analog"] inputs via your dv cams perhaps?
Also, can you really tell a difference once it's converted to dv?
What about low-light issues for movie cameras? Is it easy/expensive to get film processing?
