When it comes to a non-continous
spectrum, even the response of
different color films is different. The difference from a CCD to a film
isn't that much different as from one color film to an other. Especially
if you compare so different things as negative film and slide film or
E6 / C41 to the now extinct Kodachrome...
Film and CCDs (or CMOS sensors, basicly a light sensitive DRAM) use the
same principle of spliting up the color space into read, green and
blue. If there is a narrow spectral line inbetween (e.g. sodium lamps
for street lighting) booth will get the same problems.
Ahh, I forgot video camera tubes. They are bitten by the same problem...
