By "multiple simultaneous images", do you mean using multiple imaging devices?
(Time-multiplexing a single imager wouldn't be "simultaneous".)  If so, then,
how does one get them at the same location (or close enough not to matter, like
a pixel or two)?

There are certainly many image processing algorithms that can be applied in the
digital realm (from simple things like gamma correction, lightening, darkening,
etc.) that require a darkroom to do photographically, to the very complex (like
sharpening, edge enhancement, etc.) which are difficult, if not impossible to do
photographically.

I just wish they'd get the resolution up and the prices down faster. :-)
