And, I see on the video people inserting the darkslide into the camera door, opeinig the door after the darkslide is ejected? won't this fog the film?
No. There's a small piece of flexible plastic that covers the ejection slot when the door is opened. That being said, don't try to wiggle the film pack or put the darkslide in in bright sunlight, as there might be a little fog.
