Re: filmscanners: Pixels per inch vs DPI
As many people probably realize, in a typical rear curtain/focal plane
film cameras (as most 35mm SLRs are), any shutter speed beyond the
maximum flash synch shutter speed exposes the film via a moving slit
opening between the shutter curtains.
If, at some later date, digital sensors can be made to respond and
sample quickly enough, and the data stream could also be rapid enough,
then perhaps a moving/sweeping sensor, similar to those used in some
film scanners could be incorporated into a camera, so rather than having
to use a sensor "panel" which has to cover the full dimensions of the
area being captured, a simpler and denser populated tri-color line
sensor would be adequate, or perhaps several of these sensors could each
capture one portion of the image and then stitching it together.
