a little fact that may help:
when motion pictures/films were first being made, they were

I don't often have anything new or original to contribute to the discussion

Okay, so I ran out and got a #80 drill bit to try. Are you all putting
these in your drill?
Thanks!

Another thing occurs to me. The camera analogy is also limited by the fact
that camera shutters open and close, while light streams into the human eye
continuously. The operative 'shutter speed would have to be the duration of
exposure to the rod or cone required to trigger nerve conduction. I
Here is some information I have. How it applies I'm not sure. The eye is
only the aperture, lens and sensing apparatus. Because the eye is attached
to the brain it would make more sense to use a digital camera as a model
rather than film camera. The mind can read an image and give a response in

If the human eye/mind could be translated to camera variables..
then wouldn't it be sad to be laying on ones death bed, and start to reflect
