Got my camera stuff and started experimenting. I haven't built a rig yet, so this is for demonstration purposes only at this point. I have lots of settings I can play with (aperature, brightness of back light, shutter speed, lens used, etc.).
Here is a comparison of the scanner method vs. the camera method. In my opinion, the camera method is much sharper (one of the things that bugged me about the scanner method). I didn't clean the dust off the frame and you can see how sharp it is. Keep in mind the objects in the frame are in motion so they look blurry.
Note, I have already photoshop'd these to adjust levels, etc. The camera version needed less adjustments.
The camera version was done with some playing around with different camera settings. I haven't gotten it perfect yet.

The potential here is huge because I could fly through the scanning process once I get the camera settings where I want them and build a stable environment to advance the frames.
