cb is doing exactly what photographers have done for a century. He's the director, dp, camera operator, gaffer, focus puller, editor and colorist. That's the way still photographers have worked.
And that's the opposite of what practically all cinema, and most motion photography has been for a century. Motion is a collaborative medium due to its complexity.
Again, I'm not saying it can't be done by just one man, especially if one is not planning to shoot an Oscar-worthy feature. What I'm saying is that too many still photographers think they can just pick up a 5DII with $10k worth of gear, and shoot a short film worth watching without a script, storyboards, a story, or even a plot, are mistaken. Motion and especially cinematography has its own language, which is
very different from stills.
For a pro learning and using motion is a huge investment - and a risk. From the comments by Christopher's client it sounds like at least one is enthusiastic - but does that exuberance turn into dollars, and yield higher ROI than other investments in his business? That's something that has to be carefully gauged by each photographer.
